Abstract

Abstract: 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:① In 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.② The 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.③ Land 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.

Key words: habitat quality, geoprobes, InVEST model, land use classification, Yangquan city coal mining area
