Abstract:: Biodiversity assessment is an important method for biodiversity conservation, scientific decision-making and administration. To create the assessment index system is the key to biodiversity assessment. In this study, the county area of Ganzi Tibetan autonomous prefecture in Sichuan Province was selected as the basic assessment unit, we created an assessment index system including 8 indicators such as vertebrate richness index, vertebrate endemism index, vertebrate endangered index, plant richness index, nature ecosystem diversity index, nature ecosystem endemism index, normalized difference vegetation index, net primary productivity index, which describe the biodiversity status from both species level and ecosystem level. The weight of each assessment index was confirmed with entropy. We use this method to evaluate the biodiversity status of this area, the results show that Kangding and Litang are the most important counties with richest biodiversity assessing scores, Derong and Xiangcheng are with poor biodiversity assessing scores. Compared assessment results with the distribution of nature reserve in the study area, the results can reflect clearly the difference of biodiversity status among different counties. The distribution area of nature reserve is large in Kangding and Litang, which accounts for 44% and 17% of the total county areas, respectively, and biodiversity is better protected in these two counties. The assessment results indicate that the biodiversity is rich in Ganzi and Seda, but the distribution area of nature reserve is small, it was suggested that is more nature reserves in this two counties should be established.
