GF-1与TM影像对高潜水位矿区地表监测的比较分析∗

摘要

Large amount of high-quality cultivated land will submerge into water with the ex-ploitation of underground coal resources in high phreatic water level mining area,which will se-verely impact the security of food,ecology and economy in mining area.In order to effectively re-duce loss rate of cultivated land and improve the ecological environment in mining area,the au-thors took Dongtan Coal Mine in Jining,Shandong as an example to compare the surface monito-ring results between GF-1 with high space and time and TM images,and also verified the feasi-bility of GF-1 to surface monitoring in mining area.The results showed that GF-1 had higher temporal resolution than TM which can be important data sources of mining surface monitoring and contributed to the dynamic monitoring on mining areas'ecological environment and land-scape,in order to better building ecological,green and safe mining environment.%高潜水位矿区会因煤炭资源的开采使大量优质耕地沦为积水区，对矿区的粮食安全和生态经济安全造成严重影响，为了有效降低耕地的损失率和改善矿区的生态环境，以山东济宁东滩矿为例，采用具有高空间和时间分辨率特点的高分一号卫星(GF-1)与 TM影像的地表监测结果进行比较，验证 GF-1对矿区地表监测的适用性.GF-1数据具有更高的时间分辨率，可作为矿区地表监测的重要数据源，有助于矿区生态环境和景观格局的动态监测，从而更好的建设生态、绿色和安全的矿区环境.
