摘要：This study selected nine typical urban lake-wetlands in Daqing as the research object, and analyzed the key factors influencing diversity of the lake-wetland bird based on GIS technology and the field investigation. The bird diversity index (H ‘) was significantly positively correlated with the proportion of grassland area within the 500 m buffer zone, and the bird diversity was positively correlated with the proportion of grassland area, and grassland became the main habitat or foraging place for birds. Multiple regression analysis of common species and 10 habitat environmental characteristics parameters showed that there were inter-species differences in habitat parameters affecting distribution of birds, which was related to the differences in bird adaptability to different habitats. Moreover, the diversity of birds decreased with the increase of the proportion of urban construction land and the degree of human disturbance. So maintaining the diversity of habitat types and structures is the key to improving the richness of birds. Measures to protect the natural habitat of city and restore the effective habitat of plants and plants will help to increase the diversity of species in urban lake-wetlands.
