Spatial-temporal Evolution Analysis and Optimization of Habitat Quality in Chaohu Lake Area
Rapid urbanization is one of the key factors threatening regional ecological security and destroying human well-being.Understanding and assessing habitat quality is essential for maintaining ecosystem service capacity and promoting human well-being.Based on the dynamic degree of land use,the InVEST model was used to explore the habitat quality and degradation degree of Chaohu Lake area from 2000 to 2020,and the spatial and temporal evolution characteristics were studied by spatial correlation analysis.The results showed that the habitat quality in the Chaohu Lake region generally showed a short-term upward trend and then a downward trend.The spatial performance was higher in the southern region than in the northern region.The medium habitat quality area accounted for the largest proportion,while the high-quality area was less.The habitat quality was positively correlated with the spatial distribution,and the clustering pattern tended to be obvious year by year.Urban expansion in the Chaohu Lake area has caused dynamic changes in land structure,affecting local habitat degradation and loss of ecological functions.In the future,it is necessary to optimize the allocation of spatial resources,comprehensively consider regional differences and internal relations,and build a rational ecological network to meet the balance between regional economic development and habitat quality.
