【摘要】 [目的]对矿区生态环境变化进行检测分析,为相关环境治理措施的制定提供科学依据。[方法]以神东矿区为研究对象,基于1989—2016年的Landsat影像,采用遥感生态指数(RSEI)动态监测神东矿区及各个主要矿井生态环境时空动态演变特征。[结果]①矿区尺度上,神东矿区的生态环境质量在逐渐提升,2015年的中等及其以上等级所占面积比例为59.2%,比1989年增长了23.7%;②矿井尺度上,不同矿井的生态环境质量存在差异,榆家梁矿井整体生态环境质量最优,乌兰木伦矿井的采区和锦界矿井的非采区生态环境质量最差,相较于采区而言,非采区的生态环境较好。[结论]神东矿区各矿井的RSEI均值总体呈增加趋势,表明矿区生态环境质量逐渐变好。更多还原

【Abstract】 [Objective] To provide scientific basis for the formulation of relevant environmental control measures, this study investigated the ecological environment changes in mining area. [Methods] Based on Landsat images from 1989 to 2016, remote sensing ecological index(RSEI) was used to dynamically monitor the spatiotemporal variation characteristics in the Shendong mining area and its main mines. [Results] ① In mining area scale, the ecological environment quality improve gradually; the area with the middle and above level quality in 2015 accounted for 59.2% of the study area, and increased by 23.7% compared with the area in 1989. ② In mine scale, ecological environment qualities had differences among the different mines. The ecological environment quality in the Yujialiang mine was the best, while that in the Ulan Mulun mine and JinJie mine without mining were the worst. Compared with the ecological environment in the mining area, that in the area without mining was better. [Conclusion] The mean RSEI presented an overall increasing trend in each mine, which indicated that the ecological environmental quality became better gradually.更多还原
