Xinjiang Contains Soil Erosion in Kaidu River Basin
After more than two years of reconnaissance, collecting data, and the overall preparation of the “Kaidu River Basin Soil and Water Conservation Planâ€, it has been officially reported to the Yellow River Conservancy Commission of the Ministry of Water Resources. The 516-kilometer-long Kaidu River originates from the Halter Pass in the Tianshan Mountains. It is commonly known as the Tongtian River. In the Kaidu River Basin, there is the second largest grassland in the country, Bayinbrook Grassland and Bosten, the largest freshwater lake. The river has always played an important role in transporting water to the lower reaches of the Tarim River. However, it is not optimistic that in recent years, serious soil erosion in the Kaidu River Basin has caused serious damage to the surface vegetation in the Kaidu River Basin, resulting in a decline in soil fertility, which has led to a reduction in grass production and a reduction in the amount of livestock carried. What is more serious is that soil erosion causes a large amount of sediment to deposit in the downstream rivers, which raises the riverbed and sillines the channels. According to statistics, the rivers in the lower reaches of the Kaidu River have risen by nearly one meter from the 1980s, and parts of the river have become overhanging rivers, and the threat of floods to the coast has continued to increase. The "Kaidu River Basin Soil and Water Conservation Plan" undertaken by the Planning and Design Institute of the Upper and Middle Yellow River Administration covers the following aspects: planting trees, planting grass, returning farmland to forests and grassland, enclosure, small-scale water conservation projects, and water conservancy projects. By 2020, a total area of ​​17,053 square kilometers of soil and water loss will be managed so that the coverage rate of forest and grass in the basin will reach 33.23%. It is understood that the "Kaidu River Basin Soil and Water Conservation Plan" with a total investment of 2 to 3 billion yuan in design and planning will be implemented in two phases, namely the near and the long-term, with a planning period of 20 years. Experts commented that after the implementation of this project, the ecological deterioration of water and soil loss in the Kaidu River Basin will be fundamentally curbed.
