For understanding of the contradiction between living environment development and biodiversity protection, there are a variety of simulation data evaluation method is used to identify urban biodiversity enrichment area and sensitive area, studies show data InVEST model and real data MaxEnt model method can make up for the shortage of each other, to verify the above, this study selects typical mountain city, Hangzhou lin’an area as the research object, using simulation data InVEST model method and real data MaxEnt model method of lin’an habitat quality and birds potential suitable environment comparison evaluation, and using geodetectors to identify the key factors within them. The results showed that the areas seriously overestimated, overestimated, normal, underestimated, and seriously underestimated were 233.9 km2, 2 307.7 km2, 438.1 km2, 39.4 km2, and 2.4 km2, respectively. The climate single factor was relatively significant, and the interaction between climate factors and environmental factors was more significant. Through comparison, it was also found that the results of the two models differed significantly. The simulated data from the InVEST method greatly overestimated the mountain urban habitat quality and the potential suitable environment for birds; the real data from the MaxEnt model method showed that the potential suitable living environment for Lin’an birds was relatively poor.
