In the course of implementation, the degree of soil and water loss in the engineering construction area was increased to some extent. If not timely effective protection and governance, it will adversely affect the local soil and water resources and ecological environment. In Jiangxi Province, Nanchang Qingshan Lake head river regulation project as an example, on the basis of the overall layout of the main project, the construction layout and characteristics of soil and water loss in each area for the construction of the prevention and control of soil erosion zoning, the control area according to the different characteristics of soil and water loss and put forward measures of soil and water conservation, and suggestions for the design of soil and measures rivers in the main project is put forward in order to maintain, the river engineering soil erosion control to provide the reference.
