Chifeng City is one of the nine prefecture-level cities in Inner Mongolia Autonomous Region, with a population of 4.34 million. The total water resources in the city is 3.898 billion cubic meters, with a per capita possession of 851 cubic meters, which is 40% (2,200 cubic meters) of the national per capita possession, and it is also a water-deficient area. Topographically, Chifeng is located in the southern section of Daxing &;anling Mountains and the northern foot of Yanshan Mountains, with high terrain in the west and low terrain in the east. From the distribution of river resources, it is located in the upper reaches of Xiliaohe River, with a high altitude. As shown in the above picture (the color only represents the height, not the vegetation coverage), there are two branches in the upper reaches of Xiliaohe River, one is Laoha River, and the other is Xilamulun River, which pass around Chifeng. Chifeng, with a population of 3.43 million, is still far away from the Bohai Sea, which is far from the standard consumption level for a city that lives deep inland and has a decrease of 380 mm. With the development of economy, the population increases and urbanization speeds up, and water shortage becomes inevitable. How to solve the water shortage problem? Do you want an inter-basin water diversion, too? From the position of Chifeng, which river is rich in runoff? Judging from the rivers around Chifeng, there are only two rivers, one is Laoha River, and the other is Xilamulun River. It is difficult to find hydrological data for these two rivers, but from the perspective of river development, they are located in the upper reaches of Xiliao River, and the water volume is not very rich. These two rivers are waterless and adjustable. If we look at the first picture again, let&;s see if there are any big rivers around Chifeng. It is also difficult for us to find big rivers. The precipitation is only 380mm, and it is not easy to develop rivers. There are some lakes to the north of Chifeng. These lakes will not have a lot of water, and I&;m afraid they will be difficult to protect themselves. Over the years, with less precipitation and more population, lakes will become a problem as a water source. Secondly, Chifeng is located in a special place, at the foot of the mountains, with a high altitude. If the water in the lower reaches of the West Liaohe River is transferred, the energy consumption will not be considered first, and the high cost will not be discussed first. From the point of view of water quality, we will transfer the water back after the upstream consumption. Is this water quality good? Obviously, people don&;t approve. The location of Chifeng determines that there is no available river to transfer water, which is why big cities choose to lay out the middle and lower reaches of rivers. Big cities are located by the river, with abundant water resources. Relying on the natural purification capacity of rivers, sewage is also easy to discharge, which is especially suitable for human gathering. Although Chifeng lives in the inland, from the surrounding ecological environment, water shortage is not a big problem, which is easy to solve. The per capita water consumption here is 850 cubic meters, which is superior to that of many cities in our country, and it is still slightly surplus. As long as we fully tap the water resources here and base ourselves on the development of this basin, the problem will be solved. Xi said that &”;green mountains and green hills are the Jinshan Yinshan&”;, and Chifeng is backed by green mountains, which are the &”;natural reservoirs&”;. These mountains will raise the warm and humid air flow, and the precipitation will increase to more than 500~600mm, and the atmospheric precipitation will be stored in these forests. Judging from the runoff of Liaohe River, Chifeng District is the main water-producing area of West Liaohe River, so the green hills behind it are the high-quality water source for 4.34 million people in Chifeng, as long as we protect it well, cherish it and save water.Children and grandchildren can enjoy it endlessly and enjoy a better life.
