FEATURES OF THE ECOSYSTEM IN THE SUBTROPICAL KARST MOUNTAIN AREA AND THE WAYS OF ITS RECOVERY

The subtropical \%karst\% mountain area is mainly distributed in Southwest China and South China. Its landforms are mainly peak\|formed low\|lying lands and \%karst\% valleys that are formed by the intercalation of Cambrian system, Permian system, carbonate rocks, fragmentary rocks. Because the ecosystem is extremely vulnerable, and the interference from human activities is heavy, it is difficult for a long period to rationally exploit and utilize the resources in this area and the environment has been deteriorating increasingly. With the implementation of West China Development Strategy, such problems as the deterioration of the environment, the backwardness of the economy, and the irrational exploitation and use of resources have attracted the great attention of such academic circles as geography, \%karst\%, ecology and environment. The recovery and restoration of the ecosystem and the rational planning of agriculture, forestry and other industries have become tasks that demand immediate actions.
