Temporal and Spatial Evolution of Habitat Quality and Influencing Factors in Hefei City Based on In VEST and Geodetector Model
This article explores the spatiotemporal changes in habitat quality in Hefei City from 2000 to 2020 using a coupled model based on three periods of land use data in 2000,2010 and 2020,and analyzes the influencing factors.The results show that:From 2000 to 2020,the average values of the habitat quality index in Hefei City have been decreasing year by year respectively,with values of 0.185,0.181,and 0.178.The transfer from lower quality areas to lower quality areas accounts for the main proportion of the level change.The degradation degree of habitat quality in Hefei has been decreasing year by year from 2000 to 2020,showing a spatial distribution characteristic of"circular growth".The high degree of degradation areas are mainly distributed around the periphery of low value areas,exhibiting discontinuous expansion.Regional gross domestic product,slope,and elevation are the main influencing factors,with a significant dual factor enhancement effect.The year-end total population and population density are the dominant single factors.
