Abstract: Eco-environment investigation of the Nature Reserve is the basis for its protection,management,sustainable development and utilization.Eco-environment in Chishui Alsophila Natural Reserver was investigated through traditional method and RS & GIS technology.The results show that eco-environment of the Natural Reserve is very weak because of the high hills,steep slopes,broken landform,and the poor corrosion resistance.The contradiction between protection and exploitation is outstanding,and the human interference is increasing.Global climate change will also produce uncertain effects.In view of the present situation of eco-environment of the Nature Reserve,we should focus on the natural reserve protection and development needs,continue to improve the ecological environment research system,guide the construction of the nature reserves, do an active job in the community construction,and establish a new-style harmonious dependence relationship between the community and Nature Reserve.
