Abstract: Based on the distribution data of 17 nationally protected bird species and 25 environmental variables in Kunming, the spatial distribution pattern and high suitability zones were analyzed using the Maximum Entropy Model to evaluate the habitat suitability of birds in Kunming at a large scale. The results showed that the Dianchi Lake and its surrounding areas are important areas for birds to survive and reproduce; in addition to anthropogenic disturbances, precipitation of the wettest month(bio13), distance from water(DW) and land use type(LU) have a higher degree of influence on the suitable areas for birds, and habitat types such as cropland, woodland and grassland are more preferred by birds; there are still 14756.93 km² of unprotected areas in the bird-friendly areas in Kunming, accounting for 77.94% of the area of the suitable areas. The results of this study can provide scientific references for the conservation planning and habitat construction of bird diversity in Kunming, which is of great significance for maintaining the stability of the regional ecosystem.
