| Abstract: | In this paper, the frail ecological environment of forest in the upper reaches of Yangtse River was analysed. Based on the the discrepency of ecological environment, the frail ecological envircnment zones of forest in the area were divided 3 types, the Daofu type,Wengda type and Luhuo type. The quality retrogradation of envirornment of the frail ecological zones of forest in the upper reaches of Yangtse River indicated that the development of forest resources in the area would play an important role in the construction of forest prevention system. Some suggestions concerning this problems were made. |
