%X Based on a comparative analysis of different karst ecosystems, the research work mainly focuses on the situation of vegetation growth, the community characteristics of vegetation, the hydrochemical respondence to the system, the functions of epikarst zone, and the ecological and hydrological effects. The results show that a) the evolution stage and the damage extent of the ecosystem are well reflected by the community characteristics of vegetation; b) the inner varieties of habitat constitute the basis which makes it possible for the ecosystem to be in the process of sustainable development; c) the functions of different epikarst zones depend mainly on their specific structures and show off through their adjustment to meteorological factors of the environment and their capacity of holding water resources; d) the processes of hydrochemical respondence to the ecosystem, moreover, have reflected the differences in transportation of such substances as carbon, H 2O and calcium.
