Both of qualitative and quantitative methods are applied to screen the indicators for forest ecosystem health assessment in nature reserves in Beichuan County. The indicator weights are obtained by Principal Component Analysis, and the Fuzzy Model is built to assess the forest ecosystem health. The values show that the forest ecosystem is of sub-health with the health value 2.77, and the elevation is the most influential element to forest ecosystem health.

Keywords: forest ecosystem health assessment, principal component analysis, grey correlation analysis, fuzzy comprehensive evaluation
