摘要
采用2000年5月和2010年5月Landsat5/TM在万山汞矿地区的遥感影像数据,运用单窗算法为万山汞矿关停前和关停后的地表温度进行反演。通过反演结果,一是万山矿区关闭前地表温度明显高于矿区关闭后的地表温度,这可能由于环境治理改善所致;二是在城镇区、尾矿库区、构造发育基岩裸露地区的地表温度明显比其周边地区的温度高,无疑是这些地区植被较少的因素所致。因此利用地表温度反演,可为矿区环境治理起到一定的监测作用。
The inversion analysis of surface T before and after Wanshan Hg mine close has been carried out with single window method according to Landsat5/TM remote sensing data of Wanshan Hg mine area in May, 2000 and 2010. The inversion result： 1. the surface T of Daoshan orefield before close is higher clear than that after close,which maybe because of improvement of environment control; 2. the surface T of town, waste disposal site, basement outcrop area is higher clear than that of their surrounding area, which undoubtedly is caused by lack of vegetation. Therefore, the inversion of surface T can supervise the environment control of orefield.
