Study on the evolution of ecological vulnerability of coal mining subsidence land in Inner Mongolia Bulianta Mining area
摘要
Abstract
Ecological vulnerability serves as a crucial metric for assessing the current state of regional ecological environments.To monitor the impact of coal mining disturbances on land subsidence within mining areas,the SRP Bulianta mining land ecological vulnerability evaluation system was constructed,utilizing Landsat remote sensing data,Sentinel-1A radar data,and measured soil data.The study analyzed the changes in land ecological vulnerability and employed stepwise regression analysis to identify the most significant indicators affecting the ecological vulnerability of land in the mining area from a pool of 12 indicators.The results showed that:(1)From 2006 to 2019,the proportion of severe ecological vulnerability decreased from 8.18%to 2.82%in the Bulianta mining area,while slight ecological vulnerability increased from 24.94%to 35.24%.(2)The surface deformation index and soil fertility index were identified as the two indicators with the greatest influence on spatial variation in ecological vulnerability.Surface deformation index had a positive correlation with the ecological vulnerability of the mining region,while soil fertility index had a negative correlation with it.(3)With the extension of collapse years,the rate of land surface subsidence slowed noticeably,while the overall trend of soil fertility factors showed an increasing tendency.These findings enable rapid identification of ecological vulnerability changes in coal mining subsidence areas,revealing the drivers and trends of ecological vulnerability,thereby providing a foundation for the subsequent ecological restoration and management of coal mining subsidence areas.关键词
