摘要:
地形条件与山地灾害的发育密切相关,是山地灾害危险性评价的重要因子。以四川省芦山县"4·20"7.0级强烈地震灾区的芦山、宝兴、天全3县为研究区,应用GIS技术计算研究区坡度、地形位指数与地形起伏度,通过流域水文分析方法实现宝兴县子流域划分并提取沟床纵比降,分析灾区地形因子特征,结合灾后崩塌滑坡遥感解译结果,探讨次生山地灾害分布与地形因子的关系。结果表明,研究区坡度大于25°的面积占区域总面积的73.89%,地形位指数大于0.4的区域面积占总面积的85.92%,起伏度大于500 m的占87.41%,各地形因子面积比率最大的区段分别为坡度35°~40°、地形位指数0.648~0.666、起伏度50...
