摘要
煤炭资源在国民经济中占有非常重要的地位,而煤炭的开采则会引发诸多环境问题,制约矿区绿色可持续发展。对矿区的景观格局及生态环境时空动态监测,能为矿区生态环境治理提供决策支持,缓解人与自然之间的矛盾,引导矿区生态环境协调发展。以山东省济宁市汶上县义能矿区为研究区,基于2000~2021年Landsat影像,采用景观分类方法、景观格局指数法、遥感生态指数(Remote Sensing Ecological Index,RSEI)法和重心迁移模型,分析义能矿区景观格局及生态环境时空动态变化。结果表明:2000~2021年义能矿区最大斑块指数下降,景观破碎度和形状指数上升,煤矿开采对矿区原有景观格局影响较大;生态环境质量呈现下降—上升—下降变化趋势;绿度和干度指标对生态环境影响较大;义能矿区差等级和优秀等级迁移幅度较大。
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.
