Abstract: The construction of ecological clean watershed has great significance to the water quality safety in key water source areas. Water quality monitoring, remote sensing monitoring and hydro-morphological investigation methods were used to analyze the problems in the construction of ecological clean watershed in Danjiangkou Reservoir Area. We discussed some problems affecting river water quality, such as soil erosion, loose supervision on use of pesticides and fertilizers, irregular discharge and transportation of sewage and garbage, and artificial transformation that changes the geomorphic features of rivers. The solutions for accurate zoning and zoning governance were then proposed. The research results can provide new ideas for the construction of ecological clean watershed in Danjiangkou Reservoir Area.
