摘要
Taking southwest China as an example, the optimal parameters-based geographical detector (OPGD) was used to study the single and comprehensive effects of climate, topography, vegetation and human activities on bird species richness in the region, and determine the optimal range of single factors that promote the maintenance of bird richness. The results suggest that the spatial differentiation of bird species richness in southwest China is mainly affected by vegetation and climate factors. In the independent influence of various factors, the vegetation factor is the most important contribution, and the total contribution rate of enhance vegetation index (EVI) and forest cover height (FCH) is 33.8%‒34.7%. The interaction between the two factors enhances the influence of any single factor, and makes a significant nonlinear effect on birds richness. The study shows that the agent index of vegetation factor, especially the agent index of productivity, can better reflect the comprehensive status of the regional environment and is more suitable for the estimation of bird species diversity. © 2023 Peking University.
