Protection scheme design of residues disposal area in Southwest region karst depression
The karst geomorphology is widely distributed and typical in the southwest of China,the rocky desertification area of the land shows a trend of continuous expansion,and the land resource becomes very precious.This paper introduces a design example of residues disposal area in a karst depression of an irrigation area in southwest karst area,by analyzing the topography and geological conditions of each karst depression,the suitable protection scheme of residues disposal area is determined,and protective measures such as flood control and drainage works,seepage drainage works,vegetation recover works are implemented in a targeted manner,which solves the problem of planning and design of the residues disposal area in karst depression,the area of rehabilitation and greening is increased,and the ecological environment of the project area is improved,it can provide reference for the planning and design of residues disposal area in the karst depression of similar projects.
