【 摘 要 】

With the Hangzhou Bay where the population distribution is relatively concentrated as an example, using remote sensing technology, field investigation and canonical correspondence analysis(CCA) sequencing analysis, we studied the composition and structure of the bird community. The results show that:1)Land use and land cover(LULC) affected the composition of bird community. In the species composition of birds, 31, 30 and 18 species of birds were found infarmland, tidal flat wetland, and industrial park, respectively. In the population composition of birds, 588, 356 and 156 birds were found in beach wetland, farmland and industrial park, respectively. 2)A total of 80 birds of 6 species, 6 families, and 5 orders were recorded in the investigation area, among which 2 species were listed as the national second-class key protected animals, and 4 species were listed as the key protected terrestrial wild animals of Zhejiang Province. 3)CCA shows that the intensity of human activities affects the composition and structure of birds. 4)Habitat heterogeneity and disturbance degree are closely related to bird community composition, and bird community structure has a gradient change in order to adapt to habitat change.
