Abstract

The assessment of the importance of biodiversity maintenance functions is a significant content in the delineation of regional ecological protection red lines of China. However, estimation in this respect is less in previous studies involved in Chuxiong, an important ecological conservation area in Yunnan Province. Therefore, this study provides a quantitative estimation of the functional importance of biodiversity maintenance in Chuxiong with the Net Primary Productivity model. Then, the spatial distribution pattern of the importance of biodiversity maintenance functions was analyzed after quantile classification, and the distribution characteristics of importance levels in different land use types were explored with land use classification data. The results show that: (1) The importance of biodiversity maintenance function in Chuxiong shows a decreasing trend from the north and east to the west and south. (2) Lufeng, Wuding, and Yongren have a relatively high proportion of areas with extremely important biodiversity maintenance functions, while Chuxiong City and Shuangbai are mainly important districts. In addition, Dayao and Nanhua are mainly distributed in general important areas. (3) The important and extremely important areas of biological diversity in Chuxiong are mainly distributed in grassland, forest land and other land use types. The research results can provide a scientific basis for the delimitation of Chuxiong state nature reserves and ecological corridors, and are of great significance to biodiversity conservation.
