摘要
选择神府矿区为试验区,以1986和2003年的多时相TM影像为数据源,利用监督分类和人工识别相结合的方式对地物进行解译和分类提取。在GIS技术支持下详细计算了土地利用变化情况,并绘制了相应的动态遥感监测图。结果表明:研究区的耕地、未利用地面积明显减少;林地、城镇用地、煤矿用地面积明显增加。
The Artificial Recognition and Supervised Classification method were combined to study the database from 1986 and 2003 year respectively in Shenfu coal mine.The detail land use type was counted with the GIS technology and the trend of RS monitor graph was painted.The result showed that the arable land and unavailable land area were decreased;while the areas of forestry land, cites and towns used land and coal mine used land were increased significantly.
