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.
Abstract
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.
