开发神东矿区对生态环境的影响

基于神东矿区1986年和2008年的遥感影像资料,综合运用遥感与GIS(地理信息系统)技术手段,从土地利用/覆盖(LUCC)和景观格局指数方面分析了神东矿区开发20 a来生态环境的变化。研究结果表明:LUCC综合动态变化度减小1.01%,表明其在此期间的土地覆盖类型变化程度较小,仍属农业生态系统;矿区景观结构水平有所变化,但矿区开发并未改变矿区景观结构的支配类型,总体认为对景观结构影响较小。 Based on Landsat TM imagines in 1986 and 2008,using remote sensing techniques and GIS,evolution of ecological environment of Shendong Mining Area were studied in land use/land cover changes ( LUCC) and landscape pattern index.The results show that the integrative index of land use/land cover changes decrease 1.01%, the type of LUCC is still agricultural ecosystem;the landscape of mining area change a certain extent,but the exploitation haven't change the dominated landscape,so the influence on changing of landscape by exploitation may be suggested to be little
