摘    要:通过野外路线穿越调查和地面分辨率为2.5m的1:25000 SPOT5遥感影像解译,查明了研究区2005年沙漠化土地现状,采用TM遥感影像解译对比了1986年煤矿建设初期、1996年开发中期同时段土地沙漠化程度及面积。研究表明:20年来研究区土地沙漠化面积减少了11.67km^2。主要煤矿塌陷区土地沙漠化变化与研究区趋势相同,即重度、中度面积逐渐缩小,采煤塌陷区土地沙漠化没有出现加剧的现象。这一结论为该区大规模开发煤炭资源,同时保护生态地质环境提供了科学依据。

关 键 词:大柳塔煤矿区  土地沙漠化  遥感解译  时空演变

Abstract:By investigating desertification land in 2005 and adopting the RS(remote sensing) interpretation,the desertification land data of the initial coal mine building in 1986 and metaphase developed in 1996 are analyzed comparatively in the simultaneous time.The investigation and study show that the study areas of the desertification land had decreased by 11.37 km~2 during the past 20 years.The land desertification in the damaged area in the main coal mine did not aggravate.The degree of desertification mitigated and the area reduced.The situation was better than expected.This conclusion provides a scientific basis for large-scale coal development of ecological and geologic environment protection under vulnerable ecological environmental conditions.
Keywords:Daliuta coal mine area  land desertification  remote image  space-time evolvement
