Three measures for cross-regional allocation of resources in China: West-to-East gas transmission
South-to-North water diversion
Power transmission from the west to the east
Cross-regional allocation of resources in the Pearl River Delta and the Red River Basin The Pearl River Delta is similar to tropical deltas such as the Red River Delta and Mekong Delta. In view of the scarcity of tropical areas in China, we should give full play to the tropical characteristics and potential of the Pearl River Delta.
The cross-regional allocation of resources is due to the uneven distribution and consumption of resources. (1) the land resource reserves are large and the demand is small; ④ The land resource reserves are small and the demand is large, and the phenomenon that ① land resources are transferred to ④ is most likely to occur.

Influence of cross-regional allocation of resources on geographical environment: west-to-east gas transmission
Tarim, Qaidam, Shaanxi-Gansu-Ningxia and Sichuan basins in western China contain 26 trillion cubic meters of natural gas resources, accounting for about 87% of the national onshore natural gas resources. Especially in Tarim Basin, Xinjiang, the natural gas resources exceed 8 trillion cubic meters, accounting for 22% of the total natural gas resources in China. The natural gas resources in Kuqa area in northern Tarim Basin exceed 2 trillion cubic meters, which is the most abundant area in Tarim Basin and has the development potential of forming a world-class atmospheric zone. The discovery of natural gas in Tarim Basin has made China a natural gas power after Russia, Qatar and Saudi Arabia.
The "West-to-East Gas Transmission" pipeline project is carried out by combining dry and supporting construction, and the gas transmission scale of the pipeline is designed to be 654.38+0.2 billion cubic meters per year. The investment forecast of the first phase project is 654.38+02 billion yuan, and the total investment of upstream gas field development, main pipeline laying and urban pipe network exceeds 300 billion yuan. The project started in 2000-200 1 and will be completed in 2007. It is a natural gas pipeline with the longest distance, the largest diameter, the largest investment, the largest gas transmission capacity and the most complicated construction conditions in China. The implementation of the West-to-East Gas Transmission Project is conducive to promoting the adjustment of China's energy structure and industrial structure, promoting the economic development of the eastern and western regions, improving the quality of life of people in the Yangtze River Delta and areas along the pipeline, and effectively controlling air pollution. The implementation of this project has created conditions for the large-scale development of the western region, and it has important strategic significance for promoting and accelerating the economic development of Xinjiang and the western region by transforming the resource advantages of the western region into economic advantages.
Power transmission from the west to the east
This is one of the landmark projects of western development. Among the three landmark projects in the development of the western region, power transmission from west to east has the largest investment and the largest engineering quantity. From 200 1 to 20 10, the total investment of the west-to-east power transmission project is more than 526.5 billion (excluding the Three Gorges Power Station). Power transmission from west to east can be described as "blooming everywhere" on the Chinese territory. At the same time, the number of projects started is unprecedented, and the scale of a single project is rare. In the history of electric power construction in China, there has never been such a large-scale power supply and power grid construction. As the name implies, the key point of power transmission from west to east is "sending", and there must be channels for sending. Transmission from west to east, from south to north and from west to east will form a three-way transmission pattern of north, middle and south. The northern line transmits electricity from Inner Mongolia, Shaanxi and other provinces (regions) to North China Power Grid; The central line transmits electricity from Sichuan and other provinces to Central China and East China power grids; The southern line transmits electricity from Yunnan, Guizhou, Guangxi and other provinces (regions) to South China. The great project of transmitting electricity from the west to the east provides a new historical opportunity for the western provinces to transform their resource advantages into economic advantages, which will change the imbalance between energy and economy in the east and west. It will play an important role in accelerating the adjustment of energy structure in China and the economic development in the eastern region. Compared with other landmark projects of the western development strategy, the biggest feature of the West-to-East Power Transmission Project is that it is both a western project and an eastern project, which fully embodies the strategic concept of "coordinated development and common prosperity between the east and the west" put forward by the CPC Central Committee.
China's energy resources are not only natural gas mainly distributed in the central and western regions, but also oil, coal and hydropower. After years of exploitation, most of the coal mines and oil fields in the eastern region are in short supply. Today, with the vigorous development of modernization in China, energy shortage has become a prominent problem. Especially in the eastern region, with the deepening of reform and opening up, the contradiction of energy shortage has become increasingly acute and prominent, which has become the main limiting factor for the further economic development in many places. In order to alleviate the contradiction of energy shortage, in addition to "West-to-East Gas Transmission", "West-to-East Power Transmission" is also an important measure, which is safer, more reliable, cleaner and cheaper than direct energy transmission. Therefore, the tenth five-year plan regards the project of "transmitting electricity from west to east" as one of the key construction projects of "western development"
"Power transmission from west to east" is a landmark project of "western development". Three transmission lines will be formed during the Tenth Five-Year Plan period: the northern line will transmit electricity from Inner Mongolia, Shaanxi and other provinces to the North China power grid, and 2.7 million kilowatts will be transmitted to the Beijing-Tianjin-Tangshan area five years later; The central line transmits electricity from Sichuan, Chongqing and other provinces and cities to Central China and East China Power Grid; The southern line transmits electricity from Yunnan, Guizhou, Guangxi and other provinces to South China, and will transmit100000 kilowatts of electricity to Guangdong in five years. "Power transmission from west to east" will also promote the development of China's device manufacturing industry, power construction industry and building materials industry.
Shanxi coal sinotrans
Shanxi coal railway transportation has basically formed three major transportation channels: north, middle and south. There are Bao Jing, Daqin, Jingyuan and Huang Shen railways in the northern passage, which undertake coal transportation tasks in northern Shaanxi, northern Shaanxi and western Mongolia; The middle passage has Shitaihe-Hanchang railway, which undertakes the coal transportation task in south-central Shanxi and Shaanxi. The Taijiao and Houyue lines of Nantong Road undertake the coal transportation in the south-central part of Shanxi and some cargo transportation tasks introduced into Shaanxi by Houxi Line. The coal production in central and southern Shanxi has always accounted for about 2/3 of Shanxi's coal production, and the coal transportation volume accounts for 60% of the whole province.
The railway sea passage project in the south-central part of Shanxi mainly focuses on freight and coal as its main task. Hedong Coalfield where Lvliang is located is the largest coking coal production base in China. After the completion of the railway passage to the sea in central and southern Shanxi, it will pass through Hedong, Fenhuo, Qinshui, southeastern Shanxi coalfield, Hebi mining area in Henan, Yanzhou mining area in Shandong and other important coal tar production bases in China, which can greatly alleviate the railway transportation pressure of coal energy and ensure the national energy demand.
South-to-North water diversion
The South-to-North Water Transfer Project is a major strategic project to alleviate the serious shortage of water resources in northern China. The South-to-North Water Diversion Project is divided into three water diversion routes: the eastern route, the middle route and the western route, which greatly relieves the serious shortage of water resources in northern China and promotes the coordinated development of economy, society, population, resources and environment in the north and south. The west line project is located in the highest Qinghai-Tibet Plateau, which can control the whole northwest and north China. Due to the limited water supply in the upper reaches of the Yangtze River, water can only be replenished to the northwest and parts of North China in the middle and upper reaches of the Yellow River. The middle route project passes through the west side of the third step and takes water from the middle reaches of the Yangtze River and its tributary Hanjiang River, which can supply water to most areas of the Huang-Huai-Hai Plain by itself. The eastern route project is located on the east side of the third step, and it needs to pump water to the north because of its low terrain.
After the idea of "South-to-North Water Diversion" was put forward in 1950s, after decades of research, the overall layout of South-to-North Water Diversion was determined as: transferring water from the upper, middle and lower reaches of the Yangtze River to meet the development needs of northwest and north China, that is, the west route project, the middle route project and the east route project of South-to-North Water Diversion. Upon completion, it will be connected with the Yangtze River, Huaihe River, Yellow River and Haihe River, forming the overall pattern of "four horizontals and three verticals, north-south allocation and east-west mutual assistance" of water resources in China.
The mid-line project can alleviate the water crisis in Beijing-Tianjin-Hebei and North China, and increase 6.4 billion m for Beijing-Tianjin-Hebei and cities along Henan and Hebei. Increase agricultural supply by 3 billion cubic meters? . Greatly improve the ecological environment and investment environment of the water supply area and promote the economic development of the central region. The heightening of Danjiangkou reservoir dam has improved the flood control standard in the middle and lower reaches of the Han River and ensured the safety of Hanbei Plain and Wuhan City. Water diversion from the lower reaches of the Yangtze River basically goes northward along the Beijing-Hangzhou Canal, supplying water to the eastern part of the Huang-Huai-Hai Plain and ending in Tianjin. The Eastern Route Project was conceived in the early 1950s. 1972 After the drought in North China, the Ministry of Water and Electricity organized research. Led by the South-to-North Water Diversion Planning Office for more than 20 years, Huaihe Water Conservancy Commission, Haihe Water Conservancy Commission and Tianjin Survey and Design Institute of the Ministry of Water Resources have done a lot of survey, design and scientific research in cooperation with relevant provinces, cities and departments.
For the water receiving area, the increase of water quantity provides a basic guarantee for the water demand for economic and social development, which is conducive to the recharge of groundwater, effectively curbing the deterioration of ecological environment caused by water shortage, and protecting wetlands and biodiversity.
The influence of the East Route Water Diversion Project on the Yangtze River Estuary led to the secondary salinization of soil in the northern irrigation area.
The problem of mid-route project resettlement and its influence on hydrological situation in the middle and lower reaches of Hanjiang River. The environmental changes of the Hanjiang River caused by the Middle Route Project will cause immeasurable losses to Wuhan and Hubei, and its ecological impact is beyond the understanding of "experts".
The impact assessment of cross-regional water resources allocation on water transfer areas can be divided into the impact on nature and the impact on human beings. Then slowly separate it out, which is good for nature, improves the pressure of local water resources and is beneficial to industrial and agricultural water use; The humanistic impact on the emigrant population and the increase of domestic water consumption.
How to make geographical notes on cross-regional allocation of resources: the earth's surface (including biosphere, which can be associated with living things to better understand geography): geographical crust-landscape crust-earth's surface-bottom of atmosphere-lithospheric surface-hydrosphere-biosphere-biosphere-land-ocean-mountains-continental shelf-climate-vegetation.
Sub-disciplines.
Western scholars divide geography into two parts: physical geography and human geography, or into three parts: physical geography, economic geography and human geography, and then into two branches.
Natural aspect
Physical geography, which is studied by biology, is a systematic geography, understanding the animals and plants around the world, and using mathematics and physics to study the movement of the earth itself and its relationship with other stars in the solar system. It is a subject that studies the position and spatial changes of the earth.
