山东省矿区多维度土地利用转型对生态系统服务的空间异质驱动效应OA

Ecological degradation caused by land use transition in mining areas is severely restricting the sustainable development of resource cities.To reveal the dynamic feedback mechanism between land use transition and ecosystem services in resource-based regions,this study took typical coal mining areas in Shandong Province as the research object,constructed a"structure intensity dynamics"multi-dimensional analysis framework,and explored land use evolution and its ecological effects from 1990 to 2020.Based on the InVEST model,four key ecosystem services were evaluated,and combined with the geographical detector and spatial autocorrelation methods,the driving mechanism of land use transition on the pattern of ecosystem services was clarified.The results showed that:1)from 1990 to 2020,cultivated land in the mining areas decreased by 6.08%,construction land expanded by 7.68%,and water bodies increased by 2.71%due to coal mining subsidence;areas with medium and low land use intensity accounted for 65.39%,and the high-value areas(mining areas 1 and 5)expanded by 6.90%.2)Ecosystem services showed a pattern of"decline in the north and stability in the south";carbon storage,habitat quality,and water yield decreased by 12.3%,9.7%,and 15.8%,respectively,with significant degradation in mining areas 3 and 6.3)Land use intensity had the strongest explanatory power for ecosystem services(q>0.65),and mining areas 5 and 6 formed agglomerations characterized by"high transition intensity and high ecological degradation".The study indicates that the implicit transition dimension dominates the spatial heterogeneity of ecosystem services,and scientific regulation of land use transition can effectively alleviate the impact of human activities on ecosystem services,providing a multi-dimensional regulatory basis for ecological restoration in mining areas.
