Application of Low Impact Development in Rural River Comprehensive Regulation
Taking engineering practice as an example,the construction concept of"sponge countries"was put for-ward.Low impact development was applied to the comprehensive regulation model of rural river water environ-ment,and ecological projects such as constructed wetlands,ecological ditches and wetland bubbles were construc-ted from three aspects,including water safety guarantee,water pollution control and water landscape improvement.Low impact development simulation system software was used to analyze the governance effects of ecological measures.The results showed that the reduction rate of comprehensive runoff pollution in the target area reached 60.02%,and the reduction rate of total runoff reached 75.75%,which alleviated the flood control pressure of the river,reduced the runoff non-point source pollution,as well as improved and promoted the rural ecological envi-ronment to a certain extent.It provides a technical reference for the comprehensive treatment of water environ-ment in similar rural areas in China.
