Research on the Evolution of the Quality of Life and Space of Yongan City based on the Change of Land use and the Research of Terrain Gradient Effect
The sustainable development of the region is closely related to its habitat quality,and its development and improvement are of great significance to maintaining the balance of the ecosystem and promoting economic and social development.In this study,taking Yong'an City as an example,the In VEST model analysis method was used to evaluate the habitat quality from 2001 to 2021 and analyze its temporal and spatial evolution characteristics.At the same time,the habitat quality was combined with the topographic potential index gradient to analyze the topographic gradient effect of the habitat quality.The results showed that:(1)The average habitat quality index of Yong'an City in 2001,2011 and 2021 was 0.6354,0.6291 and 0.6285,respectively.The overall habitat level was good,but showing a downward trend.(2)There are obvious differences in the spatial distribution of habitat quality,showing that the habitat quality in the middle part of the study area is poor,and the habitat quality gradually increases as the concentrated area in the center of the study area gradually expands outward.(3)The distribution index of habitat quality in Yong'an City has an obvious topographic gradient effect,and its average habitat quality increases with the increase of topographical position.
