摘要
为实现石嘴山矿区地表环境动态变化遥感监测,选取覆盖石嘴山矿区的20世纪70年代(1970s)航空遥感图像、2003年SPOT5卫星图像和2009年RapidEye卫星图像,结合野外实地调查资料,建立了完善的地类解译标志;基于ArcGIS软件,对3个时相、不同传感器的遥感图像进行人机交互解译和解译结果叠加分析,得出1970s—2003年和2003—2009年地类变化图;通过对地类变化图的统计分析,得到矿区地类变化及相互转化情况,进而分析其变化规律及成因。结果表明:1970s—2003年间,石嘴山矿区地类变化主要体现为由基础设施建设和水土流失造成的植被覆盖区和耕地向城镇居民点及荒地的转化,而采矿活动则造成煤矸石山、煤堆、水体等地物面积的增大;2003—2009年间,植被覆盖区面积增幅最快,而煤矸石山、煤堆等矿山地物面积减小明显,这与矿区的地质环境治理恢复密不可分。
In this paper, aerial images of the 1970s, SPOT5 satellite images of 2003 and RapidEye images of 2009 were respectively selected to establish interpretation keys based on field survey, data. Then three phase remote sensing images with different sensors were interpreted by ArcGIS, and land change maps from 1970s to 2003 and from 2003 to 2009 were obtainqd by overlapping interpretation results. The change and mutual transformation of lands were analyzed, and their change rules and causes were obtained. The analytical results are summarized as follows： Firstly, from 1970s to 2003, the main change of lands in the Shizuishan mining area was that the vegetation coverage area and the cuhivated land were transformed to residential area and wasteland as a result of infrastructure construction and soil erosion. In addition, the areas of gangues, coal piles and water increased because of mining activities. Secondly, the area of vegetation coverage showed the fastest increasing rate from 2003 to 2009. On the contrary, the areas of surface features of the mine, such as gangues and coal piles, decreased sharply, which was closely related to integrated renovation of the mining geo - environment.
