摘      要：Urbanization often changes bird species richness and affects the functional ***,understanding these changes helps city planners improve green space design and land use *** study used multiple datasets to explore the effects of land-scape patterns and natural environments on the functional diversity of birds in urban parks and campuses in the eastern and northwest-ern regions of ***,we used the data to calculate birds of the functional richness(FRic),functional evenness(FEve),and functional divergence(FDiv)of 68 urban spaces in the eastern and northwestern regions of ***,we established generalized linear models of natural factors,human factors,and functional *** showed more bird species with unique traits were in the north-western *** may be because the earlier urbanization in the eastern region filtered out urban-sensitive species,leaving behind urban ***,we found that the fractal dimension index was the most significant positive factor of FRic in the eastern region but the most significant negative factor of *** was the most significant negative influence factor of FEve in the eastern region,but it was the most potent positive influence factor of FRic in the northwestern *** density had a significant positive effect on FDiv in the northwestern ***,green space areas significantly negatively impacted FEve in the northwestern *** addition,birds in parks in both regions had more functional traits than those on campuses,possibly because of the larger green space in parks,which may contain more fragments of native vegetation and reduce human *** study suggests that preserving more original vegetation and reducing human disturbance in cities can increase the functional diversity of urban birds and im-prove urban ecosystem functions.
