摘　　要：针对煤矿开采对阳泉市煤矿区的生境质量影响问题,本文基于2003—2023年Landsat影像对阳泉市煤矿区土地利用类型进行了分类,采用InVEST模型分析了煤矿区生境质量时空演变特征,并利用地理探测器探究了影响生境质量空间分布差异的驱动因素。结果表明:①近20年间土地利用类型主要由林地和草地构成,耕地面积总体较为稳定,建筑用地呈现逐年上升的趋势;②生境质量等级主要由中和较高等级构成,但其变化主要由高等级向低等级转化,呈变差状态的区域面积占比近70%,生境质量状况整体变差;③土地利用是生境质量空间分布差异的主要驱动因素,并且土地利用和其他影响因子的交互解释力最强。研究结果为政府部门生态环境治理和修复提供理论依据。The impact of coal mining on the habitat quality of coal mining area in Yangquan city is solved.Based on Landsat images from 2003 to 2023,this paper classifies the land use types in Yangquan coal mining area,uses the InVEST model to analyze the temporal and spatial evolution characteristics of habitat quality in coal mining area,and uses geographic detectors to explore the driving factors affecting the spatial distribution of habitat quality.The results show that:①In the past 20 years,the land use types are mainly composed of forest land and grassland,the cultivated land area is generally stable,and the construction land has shown an increasing trend year by year.②The habitat quality grade was mainly composed of medium and high grades,but the changes mainly changed from high grade to low grade,and the area area in a state of deterioration accounted for nearly 70%,and the overall habitat quality status deteriorated.③Land use is the main driver of differences in the spatial distribution of habitat quality,and the interaction of the other influences with land use had the strongest explanatory power.The results of the study provide a theoretical basis for ecological environment management and restoration of government departments.
