高时间跨度地类变迁与压占恢复遥感分析

Remote Sensing Analysis of Land Type Changes and Occupation Recovery in High Time Span

以宣下矿区为研究区,基于1972年、2003年、2013年、2018年4期地类数据,利用遥感技术分析了整个矿区在建矿前、生产中、闭坑后的地类变迁情况以及高时间跨度上的地类流量变化。结果表明,1972年研究区开展了大规模煤矿建设和开采活动,城乡居民与工业用地快速扩展,占用了大量耕地。分析土地的破坏与占用面积以及地貌类型发现,研究区矿山及其相关用地压占土地资源较多,破坏了地形地貌与生态环境,影响程度严重。

Taking Xuanxia mining area as the research area,based on the land type data in 1972,2003,2013 and 2018,we used remote sensing technology to analyze the land type changes before,during and after mining construction and the land type flow changes in a high time span.The results showed that since 1972,there were large-scale coal mine construction and mining activities,and the urban and rural resident land and industrial land expanded rapidly,while occupying a large amount of cultivated land.The analysis of land destruction and the landform types shows that the mines and related land occupy more land resources,damaging the landform and ecological environment.
