| Abstract: | The Shiyang River basin is one of important river basins in arid region of Northwest China.But because of the over-utilization of water resources and irrational water allocation,vegetation degradation and desertification issue in the lower reaches are very serious.So the river regulation and the protection of ecological environment are extremely urgent.In view of the serious ecological environment problem,this paper takes advantage of the technique of GIS and the method of data spatialization,obtains the me... |
