Research on the Driving Forces of Land Cover Change and Landscape Pattern Analysis in Shiguai Mining Area,Inner Mongolia
By analyzing the land cover data of the Shiguai mining area in the Inner Mongolia Autonomous Region in 2003,2013,and 2023,this paper explores the changes in land cover and landscape pattern and their driving forces.Use ENVI remote sensing software to analyze Landset-30m precision satellite images of land cover data in 2003,2013,and 2023.The changes in land cover and landscape pattern were calculated using Fragstats software.The results show that from 2003 to 2013,the Shiguai mining area mainly experienced three types of land cover transfers:farmland to construction land,irrigated grassland to con-struction land,and irrigated grassland to forest land,concentrated primarily on the southwest of the mining area;From 2013 to 2023,there were mainly three types of land cover transfers:farmland to irrigated grassland,irrigated grassland to unused land,and irrigated grassland to forest land,concentrated primarily on the southwest of the mining area.The land cover in the Shiguai mining area has continuously decreased over the past twenty years,with an increase in forest land and a decrease in irrigated grasslands.The water area is relatively stable,and unused land has decreased first and then increased.Shredded grassland is the primary coverage type of the mining area,accounting for about 80％of the entire mining area.Farmland,forest land,irrigated grassland,construction land,and unused land are fragmented and then concentrated,and some small patches transform.The prominent landscape patches are not significantly affected,and the overall landscape patches show diversified and balanced de-velopment.The changes in land cover and landscape pattern in the Shiguai mining area are mainly influenced by policy factors,including coal mine closure,shantytown relocation,Shiguai New Area,industrial park,and ecological restoration projects.The research results are consistent with the trend and magnitude of changes in various types of land in the overall land use planning of Shiguai District and have high accuracy.They can provide a theoretical basis for the high-quality construction and sustain-able development of the living environment in the mining area.
