摘要
通过对Landsat 82018年和2013年杨伙盘矿区的遥感卫星数据进行解译,选取土地利用现状、植被覆盖度、土壤侵蚀、土壤类型、水体指数、地面塌陷和坡度为评价指标,采用综合指数评价法对杨伙盘矿区进行生态环境质量评价,并对2018年和2013年进行动态监测,揭示了杨伙盘矿区生态环境质量的空间分布与变化特征。2013—2018年,生态环境质量整体变差的有24.06%,无明显变化的有49.81%,整体变好的占26.13%。杨伙盘矿区生态环境状况变差的空间分布具有由中间向南北方向的扩散趋势;植被覆盖度和土地利用对生态环境的影响最大;杨伙盘生态环境质量较差的主要分布在矿区的采掘区,活动强度大的区域,体现出高度聚集、活动性大的特点。
Through the interpretation of Landsat 8 remote sensing satellite data of Yanghuopan mining area in 2018 and 2013,Land use status,vegetation coverage,soil erosion,soil type,water index,ground subsidence and slope were selected as evaluation indexes,The ecological environment quality of Yanghuopan mining area was evaluated by comprehensive index method。Dynamic monitoring was conducted in 2018 and 2013 to reveal the spatial distribution and variation characteristics of ecological environmental quality in Yanghuopan Mine area。From 2013 to 2018,24.06%of the total eco-environmental quality got worse,49.81%of the total eco-environmental quality did not change significantly,and 26.13%of the total ecoenvironmental quality got better.The spatial distribution of ecological environment deterioration in Yanghuopan mining area has a spreading trend from middle to north,Vegetation coverage and land use have the greatest impact on ecological environment。The poor ecological environment quality of Yanghuopan is mainly distributed in the mining area,and the area with high activity intensity reflects the characteristics of high aggregation and high activity.
