Abstract: From July 2018 to May 2019, 31 sample points including 28 samples of Dianchi lakeside and 3 samples of urban waterfront park were investigated monthly for species richness of wetland birds and land cover factors. Taking the land cover parameters that significantly affect the species richness of wetland birds as the single factor index of habitat suitability index (HSI), the HSI model is further constructed to calculate the habitat suitability index (HSI) of wetland birds for various points, and the HSI_t was classified by single factor cluster analysis. The results show that among the samples in the lakeside of Dianchi Lake, the HSI_t of Dongdahe is significantly higher than that of other samples, which is extremely high, and the clustering mean of HSI_t of other samples is less than 0.6, which can be divided into 7 high, 10 middle and 10 low suitable areas. Among the 3 samples of urban waterfront park, except for Cuihu, which is a low suitable area, the HSI_t of Lianhuachi and Zhuantang are significantly lower than that of other sample points, which is extremely low.
