Abstract:

Analyzing the changes in urban habitat quality under different periods of administrative planning, and studying the impact of urban land use on the habitat quality, play an important role in regional sustainable development. Taking Lanzhou area as the research area, the InVEST model is used to evaluate its habitat quality and habitat scarcity.The results show that from 2000 to 2015, there were signs of degradation in the boundary habitats of the study area. The distribution of habitat quality showed agglomeration characteristics similar to the pattern of land use types. The overall habitat quality of the area was stable, and the areas with frequent changes and scarce habitat types are mainly manifested in grassland.

Key words: InVEST model, Lanzhou area, habitat quality, evaluation
