Abstract

In this paper,taking the case study of forest ecosystem of the nature reserve in Beichuan county for example,qualitative and quantitative methods were used to establish an assessment index system,the weight of each index was obtained by the principal component analysis,and then the fuzzy model was set up to assess the forest ecosystem of the nature reserve in Beichuan county. The results showed that forest ecosystem of the nature reserve in Beichuan county was is in a subhealthy state (value,2.77),and the elevation was the most influential element on forest ecosystem health.
