Analyze the current water and ecological problems in the Shiyang River Basin and summarize the causes of water and ecological problems in the basin. On the basis of analyzing the ecosystem composition in the lower reaches of Shiyang River basin, the ecological water requirement of Minqin oasis ecosystem is deduced. At the same time, the countermeasures and measures of Minqin oasis protection in the lower reaches of Shiyang River Basin are discussed, and the innovative idea of building a large water-saving “social-economic-ecological” complex system is put forward. Finally, it puts forward creatively the significance of establishing ecological special zones in Shiyanghe area and provides another idea for the development and ecological protection in this area.
