The ecological reconstruction countermeasure on fragile ecological environment in the karst mountainous area——With a special reference to the Gebi river area of Ziyun county,Guizhou province

Guizhou province,located in the southwest China,has a well developed karst landform.The area of the carbonate rock accounts for 73% of the total area of the province.Because of a large population,less cultivated land and lower percentage of forest,serious soil erosion and environmental pollution,the fragile ecological environment becomes deteriorate.Ecological reconstruction countermeasure on fragile ecological environment in the karst mountainous area is discussed.The purpose of the research is to find,a scientific and viable way for restoring agood ecological environment and vitalizing local economy.
