Temporal and Spatial Dynamic Monitoring of Landscape Pattern and Ecological Environment in Yineng Mining Area
Coal resources play a very important role in the national economy,and coal mining will cause many environmental problems,restricting the green and sustainable development of mining areas.The spatio-tempo-ral dynamic monitoring of landscape pattern and ecological environment in mining area can provide decision sup-port for ecological environment governance in mining area,alleviate the contradiction between man and nature,and guide the coordinated development of ecological environment in mining areas.This paper takes Yineng Min-ing area in Wenshang County,Jining City,Shandong Province as the study area.Based on Landsat images from 2000 to 2021,landscape classification methods,landscape pattern index method,Remote Sensing Ecolog-ical Index method(RSEI)and migration of the center of gravity model,the landscape pattern and ecological en-vironment change of Yineng mining area were comprehensively analyzed.The results showed that from 2000 to 2021,the maximum patch index decreased,while the landscape fragmentation and shape index increased.Coal mining had a great impact on the original landscape pattern in Yineng mining area.The ecological environment quality showed a downward trend,upward trend and downward trend.The indexes of greenness and dryness have great influence on ecological environment.The difference grade and excellent grade of Yineng mining area have a large migration range.
