Details of greening of Weihe River in Xianyang section of Baoji

The Xianyang Weihe River Embankment Greening Project is divided into 8 project sections and 9 implementation units, namely: Wugong Section, Xingping Section, High-tech Section, Qindu Section, Xianyang Lake Section, and Urban Section , Municipal Urban Construction Bureau and Weicheng Section, Jingwei New Section. The project started in early December 2008 and was basically completed in April 2009. Replanting and replanting were carried out in the spring of 2010. Up to now, *** has invested 15.3409 million yuan to build 74.63 kilometers of green forest belt near the embankment of the Wei River, equivalent to a green area of ??7450.9 acres, and planted 563,900 trees of various types. Among them: 74.63 kilometers of protective forest belt outside the embankment, with a green area of ??4371.1 acres; 27.1 kilometers of wave-proof forest belt within the embankment, with a green area of ??2738.3 acres; 40.5 kilometers of road forest on the top of the embankment, equivalent to a green area of ??341.6 acres. Excluding the construction tasks of 15.4 kilometers and 1,155 acres in the Jingwei New Section, the city exceeded the greening area by 739.9 acres, exceeding the planned task by 9.4%.

The Weihe River (Xianyang Section) landscape planning site is located in the middle and lower reaches of the Weihe River system, in the southwest of Xianyang City, and is a natural link connecting Baoji City and Xi'an City.

The conceptual theme of the planning is "Immortal Island Dragon Vein﹒Yangcheng Greenway". "Immortal Island Dragon Vein" is intended to name the location of the Weihe River landscape. It is the most famous imperial capital in China and the location of the Dragon Vein of the descendants of Yan and Huang. At the same time, the shape of the Weihe River is like a long stretching dragon, which is consistent with the cultural image of Xianyang city. "Fairy Island" refers to the ecological and cultural characteristics of the Weihe River landscape. The islands in the middle of the water look like a fairyland shrouded in clouds and mist against the backdrop of water vapor.

In order to realize the planning vision of the Weihe River, we must first solve the problems it faces. Through the analysis of the Weihe River, it faces three major problems: city and water, water and people, water and ecology. The first major problem: flood hazards and water pollution. The Weihe River is the mother river of Xianyang, but it also suffers from water pollution. The water quality of the Weihe River is classified as "V" all year round. The direct discharge of sand mining, industrial sewage and domestic sewage into the river still exists, causing the instability of the river revetments and intensifying the pollution of the river water body. Therefore, how to manage the ecological environment of the Wei River and restore a clear river to Xianyang City is the primary issue in planning.

The second major problem: the separation between the river and the city and the lack of civilization. Xianyang prospered because of the Wei River, but the development of the city is separated from the Wei River, and the lives of urban residents are not too closely connected with the Wei River. At the same time, the civilization in the Weihe River Basin never continued, resulting in a lack of culture. How to reshape the historical glory of the Wei River and become a part of Xianyang's urban development is an important part of the planning.

The third major problem: people are separated from water. There is an existing road in the Weihe River that functions as a flood control, and a retaining wall is partially installed. This creates a large vertical height difference, blocking people's visual landscape. How to bring people closer to the water, provide people with water-friendly space, and shorten the distance between them is an important part of the planning.

In response to the above-mentioned problems, the plan proposes four major development strategies for the landscape planning of the Weihe River.

The first major strategy: sort out the shoreline texture, restore habitats, and build ecological landscape corridors;

Respect the site texture and ecological pattern. Protect wetlands and farmland to determine the ecological foundation of the earth. Maintain the natural water system form of the Weihe River. Analyze the biological protection pattern and recreational environment of the Wei River, determine the Wei River rainwater utilization, biological protection, native landscape and recreational safety patterns, use the wetland purification function of plants to restore the water quality of the Wei River and create a natural ecological green corridor landscape.

The utilization of rainwater will retain and communicate the current river channels to solve the circulation and water quality problems of the water system on the site; solve water quality problems through artificial wetlands and store floods during the flood season; solve water sources through the rainwater collection system Inadequacy and waterlogging disaster prevention issues.

The biological protection security pattern should fully retain the farmland, fish ponds and wasteland outside the central area to provide habitat for organisms;

Use linear elements such as water systems and forest belts to create a native landscape experience Corridor. Establish a continuous non-motor vehicle corridor in conjunction with the water system to ensure the accessibility of the park green space and at the same time satisfy the residents’ recreation and leisure experience.

Utilize the purification function of plants to restore the natural water quality of the Weihe River and create a green corridor landscape.

Use hygrophytes and aquatic plants to plant large areas of plants on tidal flats, wetlands and waterfront edges based on the existing river waterline, implicitly increasing the water storage space of the river and improving the quality of the river. Water space environment. And use the natural purification function of plants to control water pollution in an orderly manner. Construct artificial wetlands and urban rainwater collection systems, use wetland blisters and water resources to infiltrate into green space systems and urban rainwater pipe networks to collect road water and discharge it into the Weihe River. In accordance with the drainage system that separates rainwater and sewage, all sewage pipes and factory wastewater pipes discharged to the Weihe River will be intercepted, industrial plants along the Weihe River will be relocated, and an independent sewage treatment system will be built to strictly discharge sewage into the Weihe River. After the sewage has passed through the sewage treatment plant and met the standards, it can be discharged into the Weihe River.

The planning of the Weihe River (Xianyang Section) determines different revetment design techniques based on the surrounding environment and development positioning of the site. There are mainly three types of revetments: natural revetments, bioengineered revetments and artificial hard revetments. A diverse water experience space for viewing and enjoying water.

The second major strategy: Relying on the linear skeleton of the Wei River to connect regions, combine local history and culture, and continue the urban cultural context.

On the basis of ecological and environmental protection, Xianyang’s rich historical folk cultural resources such as Xianbanqiang, Sancai Mai, and paper-cutting are integrated into the landscape design, making the Weihe River a river with profound cultural heritage. .

Under the guidance of this planning strategy, the Weihe River is positioned as a spatial structure of “one belt, two banks, three lines, five sections, and multiple gardens”. The planning uses the water belt running through the Wei River as the keynote for the entire river, and combines the "dynamic and still" characteristics of the Wei River with functional waterfronts to make full use of the waterfront environment of the Wei River. The three recreational routes fully meet the accessibility of the Weihe River and provide diversified tour needs. Five distinctive functional sections give the Weihe River a distinctive landscape theme. Multiple landscape parks take into account landscape beautification and industrial development, effectively improving the construction of Weihe River ecological industries.

Ecological wetland purification area. This area starts from the junction of Wugong and Yangling in the upper reaches of the Wei River in the west, and ends at the junction of the Wei River and Heihe River in the east, with a total length of ***31.37 km. This area is the first section where the Wei River enters Xianyang. Affected by urban industrial development, the water quality of the Wei River has been greatly negatively affected. Therefore, the function of this section is mainly to purify ecological water quality, and four major landscape groups are set up, including the Floodplain Dance Group, the Singing Birds Group, the Zhanqiao Cloud and Mist Group, and the Countryside Manor Group.

Folk culture exhibition area. This area is located from the junction of Heihe River and Weihe River to the junction of Weihe River and Laihe River, with a total length of 18km. With the help of existing ecological resources such as wetland islands in the river, it arranges ecological experience activities that tourists love to see and participate in. This area includes two groups, Yuyin Laoer and Hometown Dreaming, which take Xianyang’s folk art and material culture as their themes respectively to create a landscape with a rich cultural atmosphere.

Historical and cultural experience area. This section is located from the junction of Weihe River and Laohe River to the Xibao Expressway, with a total length of ***7.2km. This area takes the history, culture, and modern art of Xianyang City as its themes. Famous historical and cultural allusions such as the burning of books and Confucianism, Shang Yang's Reform, etc. are expressed through landscape design techniques, and participatory and experiential activities are arranged on both sides of the river. This functional section includes the Qin Feng Group and the Han Yun Group, which respectively display the cultural landscape of the two historical dynasties of Qin and Han.

City waterfront tourist area. The urban waterfront tourist area is located in the section from Xibao Expressway to Fuyin Expressway, with a total length of ***12.8km. The landscape design of this section is combined with the existing planning and design content of Xianyang Lake Park and both sides of the river. After a comprehensive analysis of the urban development strategy of Xianyang’s main urban area, this section is extended to the east and west directions to serve the daily life of the urban population. With the purpose of life and leisure, it increases the land use value of the Weihe River coastline and provides citizens and tourists with places for daily leisure and night entertainment.

New District Waterfront Recreation Area. The new district waterfront leisure area is located at the intersection of Fuyin Expressway to Baomao Expressway, relying on the currently constructed Lanchi Avenue, with a total length of approximately 16.55km. This section aims to serve the urban population in Jingwei New District, show the face of Xianyang New City, and establish the image of the city. Combined with the completed Lanchi Avenue, the theme of modernity, art, and city in the river channel is to add landscape sketches on both sides of the Wei River. , leisure service facilities and public open spaces, becoming the main connection point for the urban connectivity and development of Xianyang and Xi'an.

The third major strategy: Set up recreational spaces and roads to create a complete recreational network.

It is planned to set up a three-level road system along the Weihe River, namely embankment recreational roads, peripheral connecting roads and internal tourist roads, to ensure the accessibility of Weihe River landscape tours and viewing.

The plan *** sets up three major visual landscape systems: dynamic sightlines for riverside motorways, static sightlines for scenic spots, and bridge landscapes.

According to the planned green space system structure, the Weihe River landscape belt is divided into seven green functional zones: road greening area, parking lot greening area, protective greening area, basic greening area, characteristic scenic spot greening area, and wetland plant greening. District, waterfront green area.

The fourth major strategy: Promote economic development through project construction and promote the integration of Xixian (Xianyang Section), connect the upstream and downstream cities, use the Weihe River waters to connect the industrial connections between cities, and promote the integrated development and construction of Xixian. Wetland sightseeing, folk vacations, historical experiences, waterfront entertainment and new area display projects have been set up along the Wei River to revitalize the tourism industry of the Wei River with leisure and vacation products.

The plan sets up 9 important landscape parks along the Wei River.

The Wetland Expo Park is a linear open park on the waterfront. The park covers an area of ??about 5km. Relying on the existing water environment, hygrophytes and aquatic plant resources, and on the basis of restoring the ecological environment, a wetland expo park is set up in spots in the park as a pearl dotted on the Wei River. .

The country manor relies on the current surrounding fish ponds, farmland, fruit trees and other resources to create a comprehensive resort tourism area featuring pastoral sightseeing, waterfront leisure, ecological picking, specialty catering and farm accommodation.

The Folk Art Cultural Park is a large-scale resort park developed and constructed based on the folk culture of Xianyang City.

The park mainly develops a comprehensive art resort park with the themes of theater building, string board tune, dragon drum, characteristic folk restaurant, and folk art cultural experience house.

The folk resort is based on the material folk customs and intangible folk customs of Xianyang City. It puts aside the imperial network and heritage culture of Xianyang, and its main purpose is to serve the people in Xianyang and surrounding cities and trace the lives of people in ancient cities. Developed experiential projects.

The Historical Scroll Park is an urban linear open park, about 4km long. It mainly involves landscape sculptures, open spaces and experiential landscapes, dotted along the waterfront. Each open space does not exceed 200 square meters. Cultural allusions such as Shang Yang's Reform and the burning of books and Confucianism in the Qin Dynasty are expressed in the form of landscape. The new Chinese design style is the main tone to promote the history and culture of the Qin Dynasty and establish Xianyang. city ??image.

The plan relies on the existing Xianyang Lake Park to carry out overall landscape transformation and upgrading, organically organize the existing waterfront revetment and landscape planting, and make the park and the urban tourism distribution function The landscape of Lanchi Avenue and the historical and cultural theme park on the west side are more coherently connected.

The water children's park relies on the lake resources of Xianyang Lake Park to provide a good place for leisure and entertainment for teenagers in Xianyang City. It relies on the current environment of the south bank to build a water children's park while ensuring that the cruise ships in the lake area are not affected. The park carries out tourism activities such as water balloons, water missiles, and water bicycles. This activity has an efficient role in gathering popularity, thereby promoting the development and construction of the south bank of Xianyang City, driving the construction of new planned development plots in the south, and enriching the tourism in the lake area. content.

The Waterfront Pedestrian Commercial Street is located on the east side of Xianyang Lake, at the intersection with Lanchi Avenue. Through this commercial project that gathers popularity and vitality, it serves as the main link between Jingwei New District and Xianyang City along the Wei River. Landscape focus. This project mainly innovates in commercial formats, innovates in architecture and landscape style, creates outlets and other factory stores, and displays them in the form of waterfront blocks, serving as an important supplement to the commerce in the two cities of Xianyang and Xi'an.

The plan is to use Lanchi Avenue as the linear park in the riverside section of the new city as the new image display content of the city, and to organically connect with the Xianyang Lake area to form a continuous east-west landscape green belt.

The Weihe River Landscape Belt is not only a link, tying the friendship between cities, but also a zipper, fully integrating the city and ecology, and becoming an important ecological river, landscape river and vitality in the region. river.
