摘要: 利用Landsat系列卫星、国产高分卫星遥感影像,笔者调查研究了南水北调水源区(河南段)石漠化现状,结合GIS技术,将1996年、2006年、2016年三期石漠化调查结果进行叠加分析,获取1996-2006、2006-2016两期石漠化变化趋势。结果表明,研究区生态地质状况总体良好,尤其在部分石漠化发育严重区域,其生态地质状况发生了颠覆性改善。基于遥感技术开展南水北调水源区(河南段)石漠化遥感调查与监测结果,并结合确定性系数方法对石漠化进行易发性评价,研究表明,评价综合分区与石漠化分布基本吻合,调查方法可靠。开展本项目查清研究区的石漠化状况,并对石漠化进行分类分级、揭示演化特征,提出治理措施。

Abstract: The authors use the Landsat and high-resolution satellite remote sensing images to investigate the current situation of rocky desertification in the water source area of the South-to-North Water Diversion Project (Henan section). Combined with GIS technology, the results of the three rocky desertification surveys in 1996, 2006 and 2016 are superimposed to obtain the trend of rock desertification in 1996-2006 and 2006-2016. The results show that the ecological geological conditions of the study area are generally good, especially in some areas with serious rocky desertification development, the ecological geological conditions have been subversively im-proved. Based on the results of remote sensing survey and monitoring of rocky desertification in the water source ar-ea of the South-to-North Water Diversion Project (Henan section), in combination with evaluating the susceptibili-ty of rocky desertification using the deterministic coefficient method, it is indicated that the evaluation comprehen-sive zoning is basically consistent with the rocky desertification distribution, and the survey method is reliable. The project has been carried out finds out the status of rocky desertification in the study area, and classifies the rocky desertification, reveals the evolution characteristics, and proposes the control measures.
