地形起伏度和坡度分析在区域滑坡灾害评价中的应用

摘　要：基于ArcGIS平台,利用SRTM3-DEM数据资料,选择鄂尔多斯及其周缘为研究区,计算并定量分析了地形起伏度和坡度,并利用区域滑坡灾害调查资料,初步建立了地形起伏度、坡度与滑坡灾害之间的相关性,讨论了地形起伏度的区域地貌意义.结果表明,研究区滑坡集中发育地区的地形起伏度为200～300 m,在此范围内滑坡占研究区所有滑坡总数的48.5%.此区间的面积占研究区总面积的20.3%;坡度为10～18°,此范围内滑坡占研究区所有滑坡总数的46.7%.而此区问的面积占研究区总面积的30.5%.在地貌类型上,滑坡集中发育地区对应残丘、黄土塬及黄土墚等.通过研究区横向、纵向剖面的地形特征分析,表明地形起伏度和坡度分析是相互补充的,它们均与区域滑坡发生和分布存在良好的相关性.这种相关性为区域滑坡灾害评价提供了新的思路,对区域防灾规划和灾害区预测具有重要的应用意义.
