摘要
以神北矿区为例,以遥感解译和野外调查为手段,选用煤矿开采初期(1987年)、中期(1992年)及近期(1999年)三期卫星遥感图像,分析了研究区内土地沙漠化三期分布特征及变化趋势,对比了煤炭开采区与煤炭未采区土地沙漠化变化趋势的不同,探讨了矿区内沙漠化面积年自然增长率以及煤炭开采对沙漠化影响程度,认为煤炭开发初期环境破坏加剧,造成土地沙化面积增加,矿井正常生产时期,由于环境治理力度加大,土地沙漠化趋势出现逆转,为矿区土地沙漠化恢复治理提供了依据。
To take the Shenbei mining area as an example, the paper systematically analyzed the regional distribution characteristics and development trend of desertification of land in the study area by means of remote sensing interpretation and field investigation. In addition, the dissimilarity is contrasted between coalmine exploited and the unexploited areas. Then natural increase rate of land desertification in Shenbei mining area, coal mining impact to land desertification and governing countermeasures are discussed. The paper has also provided governing basis for restoration of land.
