Land use and habitat quality change in Yichang Citybased on InVEST model
To investigate the impacts of land use and habitat quality on the spatio-temporal evolution of Yichang City and to offer scientific guidance for ecological environmental conservation and high-quality regional development,land use classification data from 2005,2010,2015,and 2020 were employed.The GIS,InVEST model,and principal component analysis were employed to investigated the classification data of alterations in land use and habitat quality.The results show that alterations in land use and habitat quality in the studied region revealed a noteworthy transformation from 2005 to 2020 due to local population and economic evolution.Specifically,the most significant increase was observed in the area designated for construction,with a growth rate of 77.93%;the largest expansion oc-curred in arable land,eaching 32,175 hectares,primarily attributed to the conversion from forest,water bodies,and grasslands;The transfer area of forest land is the largest,about 156,186×103 hectares,and land use transfer is significantly affected by local population and economic factors.The overall habitat quality level of the region showed a downward trend,the area of low-level habitat quality con-tinued to expand,and was slightly improved by 2020,while the area of extremely high habitat quality continued to decrease and degraded into high and relatively high habitat quality levels.The overall habitat quality level of Yichang City was very high.The distribution of land use types is strongly associated with the spatial pattern of habitat quality.Areas that exhibit high habitat quality are predominantly found in regions with expansive ecological space,including woodland and grassland.Conversely,areas characterized by frequent human activities tend to have low habitat quality.
