Abstract: It can provide reference for community restoration to master the health situation of life community of mountains, rivers, forests, farmland and lakes. This paper, taking the Hongfeng lake as the research object, established SC model which defined as HI (ecosystem health) = V·O·R to evaluate the health of life community. 27 index levels in the evaluation system were set by referring to international and national industry standards, relevant literatures, while some indexes without clear standards were defined by standardized or natural break method. And the weightiness of the index system was confirmed by the AHP method. The results showed that: (1) the health of life community in research area belongs to a sub-health state, (2) the H index was lowest due to hundred-year drought in 2010, (3) there was a correlation between the basic state index of mountains and come indexes of other subsystem state, (4) the basic state (S) index of life community was related to the intensity of forests and lakes, and (5) the increase of H index was attributed to the improvement of the basic state of the lake from 2005 to 2015. In conclusion, the main factors affecting the health of the life community were identified as topography and geomorphology, extreme rainfall, water conservancy projects and ecological protection measures. Finally, some suggestions were given on health maintenance of life community from five aspects of protection of key lakes, optimization of the ecological environment of reservoirs, implementation of flood control and drought resistance water conservancy projects, development and construction of key industrial areas and the treatment of water and soil loss.
