2 City and Urbanization

2.0. 1 settlement

Residential area? The whole country is divided into two categories: towns, villages located in counties transformed into townships, cities where township people's governments are located, rural areas and towns.

City (town)

This city is a central region with certain economy, politics and culture. The concept of urban management refers to the national administrative system, which is established in our municipalities, cities and towns. The state requires the county people's government to be located in the town.

2.0.3 Cities

China's administrative divisions are approved by the municipal agencies of the administrative regions of the country and the municipalities directly under the central government, provinces, cities and prefectures. Population size, cities are divided into big cities, medium cities and small cities.

cities and towns

In China's administrative divisions, city is the abbreviation of town. After the town is the seat of the county people's government, the town and county seat shall be established.

2.0.5 Market

City, county and city leaders (also called counties and cities), in the current administrative divisions, municipal districts include all county leaders within the administrative jurisdiction. The city implements the administrative jurisdiction of counties, cities and cities.

the satellite towns

Satellite towns in the process of urban development. The construction of satellite towns, in order to prevent excessive expansion, aims to attract the life of urban population in large and medium-sized cities, and attract the population scale of big cities that are ready to enter the urban population from other places.

Overview of urban planning

3.0. 1 urban system planning

According to the Urban Planning Law, the urban system planning and urban master planning promulgated by the Ministry of Construction should, in principle, determine the outline of the urban system structure and layout in the city (county) area. Including: analyzing the conditions and constraints of regional development, regional urban development strategy, determining the comprehensive objectives of resource development, industrial layout and ecological environment protection, predicting the level of regional urbanization, historical and cultural inheritance and scale structure of APV urban system; , the function and spatial layout of the department, to determine the development of key towns; Area is determined by principle? Layout of transportation, communication, energy, water supply, drainage and flood control facilities; Carry out the planned technical and economic policies, measures and suggestions.

city planning

From the theme of the speech, urban planning is a comprehensive discipline, involving sociology, architecture, geography, economics, engineering, environmental science, aesthetics and other disciplines. Administration and urban planning are important responsibilities and work of the government.

In 1950s, concrete continued to be used in urban development and urban planning. He said that by the early 1980s, urban planning was a comprehensive deployment of urban development planning and construction in a specific period. With the deepening of development and reform, it is generally believed that urban planning should not only be the physical environment planning in preparation, but also include the concepts of urban economic and social development, overall land use planning, spatial layout and construction projects.

Urban planning is generally divided into two stages: comprehensive planning and detailed planning.

Preparation, approval and implementation management steps of urban planning from formulation to implementation. The needs of urban planning and urban economic and social development do not meet the procedures prescribed by law, and the overall urban planning is partially adjusted or even made some major changes.

3.0.3 Urban design

Urban scale and spatial environment, urban design, urban design should consider the basic elements of basic material elements, such as buildings, roads, green spaces, natural terrain, basic material elements, and sort the urban space demand and the overall image of the city, from small and warm courtyard space to grand city square, until the image of the whole city exists in natural space.

3.0.4 Urban planning scheme

12 according to the architectural and urban planning scheme and urban planning law issued by the Ministry, it should include the following contents:

(1) A model city is a condition for the country's economic and social development, and it is the principle of urban development goals during the planning period.

(B) the status of demonstration cities in regional development. Determine the system structure and layout of cities (counties) in principle.

(c) Determine the principles of the nature of the city and the scale of land used for the overall layout of urban development, and put forward preliminary opinions within the urban planning area.

(four) to study and determine the major principles of the development and construction of urban infrastructure such as urban energy, transportation and water supply, and the important measures for the implementation of urban planning.

Urban area

The difference lies in the urban built-up areas of single-core cities and cities above cities. In the area adjacent to the built-up area, the actual development focus of basic municipal public facilities and public facilities construction has been dispersed to the blocks in the development and construction of a single core city, and municipal public facilities and public facilities areas have been basically ready. For the remaining towns of a city, several continuous areas of basic municipal public facilities and public facilities will be developed and built in the built-up area. Lianyungang City, Zibo.

3.0.7 Development Zone

According to Decree No.43 of the Ministry of Finance of People's Republic of China (PRC) and the Measures for the Administration of Development Planning of China, the central technological development zone and economic development zone established with the approval of the State Council and the people's governments of provinces, autonomous regions and municipalities directly under the Central Government, China implements specific national preferential policies in the development and construction fields of urban planning areas, bonded zones, high-tech industrial development zones and national tourist resorts.

urban infrastructure

There are two kinds of urban infrastructure: engineering infrastructure and social infrastructure. Project infrastructure generally refers to energy supply, water supply and drainage, transportation, postal services, telecommunications, environmental protection, disaster prevention and safety engineering facilities. Refers to social infrastructure such as culture, education and medical care. China generally emphasizes urban infrastructure projects.

3.0. 10 Urban Master Plan

The main tasks of urban master plan are: comprehensively study and determine the nature, scale and spatial development mode of the city, rationally allocate urban construction land, the relationship between urban infrastructure construction and long-term development and the overall arrangement of recent construction, and guide the rational development of the city. The planning period is generally 20 years.

3.0. 14 Regulatory Detailed Planning

23 "Urban Planning Law" promulgated by the Ministry of Construction, the regulatory detailed planning shall include the following contents:

(a) the planning provides for the use of land within different types of boundaries, and applies to the provisions of construction, but it does not apply to all types of land, construction or construction types where conditions permit.

(b) Clarify the distance between pedestrian entrance, parking lot and building red line and the building spacing in the direction required by control indicators such as building height, building density, plot ratio and green space.

(c) The quality, size, color and other requirements of the proposed building.

(d) Determine the red line position, control point coordinates and elevation of branches at all levels.

(five) the diameter is determined according to the land boundary of the planned production capacity and the direction of the engineering pipeline of the engineering facilities.

Formulate corresponding laws and regulations on land use and construction.

3.0. 16 urban planning and management

Urban planning management, including management, urban planning, urban planning approval management, and urban planning implementation management. Urban planning management is the organization of urban planning, soliciting and coordinating comprehensive planning in all aspects to ensure high-quality results, reports and management. The examination and approval system of urban planning documents is suitable for the management level of urban planning examination and approval. The implementation and management of urban planning, including land planning management, construction, supervision and inspection of construction projects and planning implementation management.

4 urban planning

4.2 Urban population

4.2.3 Urban population growth

According to the absolute number of urban population growth, urban population growth can be divided into three situations: net population growth, zero population growth and negative population growth.

4.2.4 Urban population growth rate

The calculation formula for the increase or decrease of urban population reflected by the index of urban population growth rate is:

Urban population growth rate = (urban population growth rate this year ÷ average absolute number of urban population) × 1000(‰)

4.2.5 Natural growth rate of urban population

The natural growth rate of urban population is the basic index reflecting the natural increase or decrease of urban population, and its calculation formula is:

The number of people born in urban areas, the natural population growth rate = (the number of deaths in that year-the number of deaths this year), and the average annual total urban population is 1000 (thousands of people).

4.2.6 Mechanical growth rate of urban population

The mechanical growth of urban population reflects the population growth caused by the change of urban population index. Due to social factors such as immigration and immigration, its calculation formula is:

Mechanical growth rate Urban population = (this year's urban population-this year's urban population) ÷ average annual total urban population 1000 (‰).

4.3 Urban land use

4.3.2 Residential land

According to the national standard "Standard for Urban Land Classification and Planning and Construction Land" (GBJ 137 90), this interpretation is applicable to the compilation of the overall urban planning. In the planning of residential quarters, you can still match the house according to the living area, that is, the residential land and supporting facilities.

4.3.3 Land for public facilities

GB GBJ 137-90 2 .0.5 stipulates that public facilities in public service areas include residential land.

4.3.4 Industrial land

Industrial land specified in GB GBJ 137-90 2 .0.5, excluding open pit land, should be classified as "water and other websites" (code E).

Roads and squares

GB GBJ 137-90 2 .0.5 stipulates that the land for roads and squares should be roads, square spaces and public parking lots.

Road use refers to the websites of main roads, secondary roads and branch roads, including the land at their intersections, excluding roads with residential land and industrial land. Primary and secondary roads and land for roads other than anti-skid, such as pedestrian streets, bicycle lanes, roads, etc.

Square land refers to public square space, excluding unit square land.

Public parking garage space refers to the land used by the public, including social parking lots and parking lots (including public transport vehicles and private cars), excluding other types of land for building parking garage websites.

4.3.8 Municipal public facilities

According to GB GBJ 137-90 4.0.5, municipal public facilities (water supply, power supply, gas and heating facilities, including water supply facilities and land, but not included in land supply, should be included in industrial land, land under the control of power plant high-voltage corridor, and on the ground according to its actual use) and transportation facilities (public transportation and freight). "Land" (land for postal services, telecommunications, postal facilities and telephone facilities), environment (rainwater, sewage treatment and garbage disposal), sanitation, land, construction and maintenance facilities, land, land funeral facilities and other municipal public facilities, such as fire control, flood control facilities and land.

Safe prisons, detention centers, labor systems and land for security departments. Excluding the Public Security Bureau and the Public Security Bureau, the land should be classified as the land for public facilities (Article 4.0.5 of GB GBJ 137-90).

4.3. 13 Urban Land Evaluation

In the evaluation of urban land, the engineering evaluation department usually evaluates the suitability of land for construction according to the buried depth of groundwater level, natural conditions of urban construction land, engineering evaluation, bearing capacity of foundation in submerged area, slope and other natural conditions. The general evaluation is divided into three levels: the suitable land for urban construction refers to the land that should be built after certain engineering measures need to be taken; Third, it is not suitable for construction sites.

4.4 Overall layout of the city

4.4. 1 urban structure

Urban structure, including population structure, social structure, industrial structure, land use structure and network structure, is relatively stable.

4.4.2 Urban layout

Urban layout refers to the physical environment of the city, such as the relationship between urban functional zoning and natural environment (mountains, rivers and lakes, green space system), as well as the spatial layout of important transportation hubs, road networks, urban land, etc.

4.4.4 Urban functional zoning

The purpose of urban functional zoning is to ensure the normal activities of the city, so that the functional areas are interrelated and avoid mutual interference. Since 1960s, urban functional zoning has made new development in theory and practice. For example, Milton Keynes Park built by 1970 in Britain did not set up an excessively concentrated industrial zone, and formed a living area including factories, administrative institutions, many houses arranged nearby, economic and cultural management institutions and efforts to balance employment and housing on the spot. The Machu Picchu Charter was signed in 1977, which emphasized in Peru that efforts should be made to build a comprehensive and multifunctional environmentalist and not to excessively pursue strict functional zoning.

central business district

The concept of Central Business District (CBD) was put forward by American Burgess in the 1920s, which means that CBD includes department stores, offices, entertainment places, public buildings and other facilities, as well as replicas of core units in cities. With the development of, in recent years, the global industrial structure has increasingly become the economic activity of a comprehensive city center, such as Wall Street in new york, Pudong New Area in Shanghai and Lujiazui area on the Bund under planning and construction. Its main functions are: urban business negotiation places, finance, trade, housing exhibitions, conferences, business management, tourism, apartments, commerce, culture and entertainment, plus modern communication networks and transportation facilities.

4.6 Urban Road Traffic

Urban road system

Urban road system, grade and location roads: traffic roads and life roads, such as roads divided according to different functions; Different levels are divided into expressways, main roads, secondary roads and anti-skid. According to different locations, there are huge and important distribution points between cities, convenient road freight, transit freight passages set on the edge of cities, and pedestrian roads in commercial pedestrian areas.

highway

According to the Code for Design of Urban Road Traffic, the design speed of expressway with motor vehicle lanes is 60? At 80km/h, the median of two-way roads between expressways should be set.

4.6.7 Urban road network density

Urban road network density km/km2. The length of the road center line in the road network shall be calculated according to the land used within the service scope of the road network. Roads refer to the main roads, secondary roads and branches of the urban road network, excluding residential areas.

4.6.8 MRT

Refers to the large passenger capacity, large capacity and theoretical research shows that the design is reasonable and effective, and the operation speed range of the bus lane is 16? The flow of 22 kilometers per hour can reach 25 million passengers per hour. You can also use this MRT bus, light rail or subway.

pedestrian street

All-day or limited time (for example, 9 am to 7 pm every day) pedestrians; Pedestrian streets and management in cities are generally divided into two situations: pedestrians are generally allowed to pass, and vehicles are prohibited from entering, but special vehicles such as delivery vehicles, sweepers and fire engines are allowed to pass. Some cities allow buses to pass through fixed lines. In the business district of the city, it is also called the commercial pedestrian street.

4.7 Urban Water Supply Project

water conservation

Measures to protect public water sources in the city include: water sources around water source protection areas (including restricted areas); Dynamic monitoring of water sources and regular analysis of water quality changes.

4.7.7 Urban water supply system

Urban water supply system is usually aimed at towns with a certain scale, and only one public water supply system can be established. Because of different water pressures and economically reasonable water quality requirements, the use of two or more completely independent or independent public water supply system networks is called "regional water supply" or "quality water supply".

4.8 Urban Drainage Works

urban sewage

Runoff polluted by urban sewage, rain and snow drench urban air pollutants and clean buildings, ground, garbage and sewage, which have the characteristics of seasonal change and complex composition.

4. 1 1 urban heating project

4. 1 1. 1 urban central heating

Urban central heating boiler room adopts centralized heat source, or a certain amount of industrial waste heat, or uses geothermal stability and regional heat source.

4. 13 urban green space system

4. 13.2 urban greening

The distribution of urban green space system generally needs unified layout. Combined with the characteristics of natural terrain, cities are connected by points (small green spaces evenly distributed) and lines (road green spaces, cities, urban sightseeing cities and villages, green belts, etc.). ) and the ground (referring to the greening of parks and scenic spots) form an overall green space.

4. 13.4 Park

Park is a major part of urban public green space system. It plays a positive role in protecting the environment, standardizing people's lives and beautifying the city. Parks can be divided into two types: city parks and nature parks. Parks here refer to urban parks, which can be divided into comprehensive parks and theme parks (such as zoos, botanical gardens and children's parks) according to different scales and functions. Usually refers to a national park in a natural park.

4. 13.5 green belt

1At the end of the 9th century and the beginning of the 20th century, ebenezer howard, an Englishman, in his book Garden City of Tomorrow, advocated gradually realizing the social zone of land ownership, building a garden city and creating a new society integrating urban and rural areas. This method is used in the green belt of garden city, but Howard cited the precedent of Adelaide, Australia, and pointed out that the parks in Adelaide surrounded the land of the city and had been built. How will it grow and develop? The whole park land was built for the development of northern Adelaide. Principle, but this is to imitate the improvement of garden city. "

1938 promulgated the "British Green Belt Act" to protect the Greater London area and surrounding counties and cities in the form of law and limit the spread of urban land.

A certain width of green belt can prevent urban expansion, protect the future development land of the city, provide recreational environment for urban residents and protect the ecological balance of the city.

4. 13.6 Special green

In the land use classification of green space cities, they belong to different land types. The article "Classification of Urban Land in Industrial Land under Factory Green Space and Standard for Planning and Construction Land" (GBJ 137 90) points out that special green space does not include institutions whose campus green space belongs to the website of colleges and universities.

4. 14 urban environmental protection

4. 12.2 Urban ecological balance

Urban ecosystem consists of four parts: abiotic substances and energy, including sunlight, temperature, air, water and mineral producers, mainly refers to green plants transforming inorganic nutrients into organic nutrients through photosynthesis, storing them in organic light energy and transforming them into chemical nutrients; 3。 Consumers, all kinds of animals including human beings; 4。 Decompose bacteria and other microorganisms, mainly. Urban ecological balance refers to the relationship among producers, consumers and decomposers in urban areas to maintain a relatively stable state.

4. 15 Protection of urban history and culture

4. 15. 1 historical and cultural city

1994, China was approved by the State Council as a famous historical and cultural city. There are 99 famous historical and cultural cities in China, among which the first batch was listed on the protection list for the first time. There are 24 cities including Beijing, Suzhou, Hangzhou, Guangzhou, Zunyi and Yan 'an, among which 38 cities including Shanghai, Wuhan, Tianjin and Harbin are on the protection list. China's historical and cultural cities are divided into national and provincial levels. To be named as a national historical and cultural city, we must first go through a provincial historical and cultural city approved by the provincial people's government.

4. 15.4 protection of historical sites

The regulation of "preservation" generally means that key cultural relics protection units shall not make any changes (including reconstruction and demolition) in accordance with relevant regulations and planning requirements. "Protection" generally refers to the protection of real history, traditional blocks, residential areas and the overall style of enterprises. "Maintenance" generally refers to important safety work, such as fire, flood, snowstorm and earthquake. Without establishing specific maintenance and repair work.

4. 16 urban disaster prevention

4. 16.3 urban flood control standard

The regulation of importance says that the important basis for formulating urban flood control standards is the importance of a city and its political and economic status in the country. Flood types can be divided into four types: river flood, tsunami, flood and debris flow. Urban flood control standards are usually divided into design standards and inspection standards. Normal operation design standards, design flood control projects and protected objects (such as towns, factories, mines, farms, etc.). When flood flow occurs, it is safe to carry out flood. Check that the standard flood flow is greater than the design flood flow, and the flood control project will not have problems such as breach, dam collapse, exchange and river flood discharge.

4. 17 vertical planning and engineering pipelines

4. 17.2 Urban Pipeline Project

The traditional pipeline synthesis of various urban engineering pipelines refers to municipal engineering, water supply, drainage, electric power, telecommunications, gas and heating engineering pipelines. Provisions, the so-called overall arrangement, will only make the city unified coordinate system and height system, the overall arrangement of various projects and the spatial location of pipelines, and avoid incoherence and confusion. Overall planning, coordination, comprehensive consideration of topography, geological conditions, the required distance between neighboring countries, the intersection of horizontal and vertical distances of engineering pipelines, urban roads, pipeline engineering and other engineering facilities, the aesthetic requirements of urban facilities safety and environment, and coordination to solve the contradiction between pipelines and their proper positions in the project and urban engineering.

5 urban planning and management

Planning approval procedure

Urban planning must adhere to the grading examination and approval system to maintain the seriousness and authority of urban planning. The Municipal People's Government approves the urban planning scheme.

"People's Republic of China (PRC) City Planning Law" stipulates that the approved urban master plan:

The overall urban planning of a municipality directly under the Central Government is approved by the State Council.

The delineation of cities where the people's governments of provinces and autonomous regions are located and other cities with a population of more than US$ 65,438+0,000 in the master plan shall be approved by the people's governments of the State Council, provinces, autonomous regions and municipalities directly under the Central Government, and the master plan of cities where county-level governments are located and towns under municipal jurisdiction shall be approved by the municipal people's government.

The overall planning of other towns shall be reported to the people's government at the county level for approval.

The Municipal People's Government and the people's government at the county level shall obtain the approval of the Standing Committee of the people's congress at the same level before submitting the withering test report of the overall urban planning to the people's government at a higher level.
