Abstract:

The assessment of habitat quality plays an important role in maintaining the regional ecosystem and reshaping the regional ecological security pattern.This paper selected the Chang-Zhu-Tan urban agglomeration as the research object,used the InVEST model and ArcGis software to analyze the spatial pattern and spatial evolution characteristics of regional land use and habitat quality in 2000,2010 and 2020,respectively,and further analyzed its evolution mechanism and influencing factors.The results showed that:1)The distribution of land use and habitat quality level had obvious correlation;2)The overall habitat quality of the Chang-Zhu-Tan urban agglomeration had experienced an evolutionary trend from maintaining in great efforts to accelerating deterioration;3)The dynamic evolution of habitat quality level was obviously related to the release and implementation of regional planning policies.

Key words: Changsha-Zhuzhou-Xiangtan urban agglomeration, habitat quality, InVEST model
