中文摘要：

为了评价利用北京一号小卫星（BJ—1）遥感数据监测煤矿区土地利用／地表覆盖变化的效果，针对其数据特点，选择基于图像信息运算和图像信息变换的直接变化检测法以及分类后比较法，对徐州东矿区2007～2008年土地利用／地表覆盖变化情况进行检测，以对比、评价各种方法在土地利用／地表覆盖变化检测中的应用效果和BJ-1数据的适用性。结果显示，变化矢量分析法的检测精度最高，其后依次为图像比值法、图像差值法和多波段主成分分析法。通过变化检测，确定徐州市东矿区土地利用／地表覆盖变化较为集中的几个区域，包括东矿区北部的青山泉矿、韩桥矿、董庄矿和南部的大黄山矿等地区。

英文摘要：

In order to evaluate the performance of monitoring land cover change in mining areas by BJ - 1 small satellite remote sensing data, the authors made an experimental and comparative study of several change detection methods, with the east coal mining district of Xuzhou City in Jiangsu Province as the study area. Direct change detection methods based on image information operation and image information transformation as well as the post - classification comparison method were adopted in the experiment. The results show that the change vector analysis can attain the highest accuracy, followed by the method of image ratio method, image differencing and multi - band principal component analysis. Through the change detection process, several areas with great land cover change were detected, such as Qingshanquan, Hanqiao and Dongzhuang mining areas in northern east mining district and Dahuangshan mining area in southern east mining district.
