Abstract Habitat quality is an important spatial dynamic factor for evaluating the effectiveness of biodiversity conservation. This study aimed to understand the characteristic variation of habitat quality in Shangri-La City, which can provide a basis for decision-making by relevant departments to protect the biodiversity of the area. The spatiotemporal variation of habitat quality of Shangri-La City in 1989-2015 was estimated based on the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model. The results showed that: (1) The overall habitat quality presented a decreasing trend from 1989 to 2015, with Jiantang, Naxi, Xiaozhongdian, the northern part of Hutiaoxia and the southern part of Sanba the most significant. (2) The highest value of the average habitat quality of Shangri-La City was located in the middle-elevation regions, while the lowest value was located in the low-elevation areas, and the average habitat quality of the two regions showed a decreasing trend from 1989 to 2015. (3) The average habitat quality of the steep and extremely steep slopes in Shangri-La was higher than that of the slight slopes. This study was useful for biodiversity conservation policy-making for ecological fragile region in China.
