摘　　要：利用2011年SPOT5和2016年GF1遥感影像数据,通过计算机自动提取与人工交互解译相结合、室内解译与野外查证相结合的方式,调查河南省栾川地区矿山占地动态变化信息。对比分析发现,2016年工作区内矿山占地图斑共144处,总面积共14.74 km^2,其中尾矿库图斑面积最大,其次为采场图斑,第三为废石堆图斑,分别占矿山占地图斑总面积的47.08%、31.41%、16.95%。2011—2016年变化图斑共25处,其中扩张图斑19处,新增图斑6处,面积共增加了2.56 km^2,矿山恢复治理图斑无变化。Using the SPOT5 in 2011 and GF1 in 2016 satellite images as the main sources of data,the authors investigated the dynamic change of mining occupied land in Luanchuan region of Henan Province,by the combination of computer automatic extraction and man-computer interactive interpretation,and the combination of indoor interpretation and field verification.The comparative analysis shows that 144 mine development polygon features are interpreted from the multidate satellite images,with a total area of 14.74 km 2.Tailing pond,stope and dump are the three most important types of polygon features in the study area,accounting for 47.08%,31.41%and 16.95%of the total area,respectively.From 2011 to 2016,25 changed polygon features are interpreted from the multidate satellite images,including 19 expanding polygons and 6 new added polygons,with a total area of 2.56 km 2.It shows no change in the rehabilitative situation.
