使用传统的数量化理论可以把定量和定性的指标结合起来综合判断滑坡发生的危险性,而这些方法在实际应用时面临的问题是如何高效率和高精度地定量把握各种滑坡影响因素的空间分布(如地质、倾角、土地利用、地形起伏、汇水面积等).提出基于GIS的空间数据输入方法,通过矢量数据和栅格数据变换来快速高效地解决数据的准备问题,同时制作接口将这些数据输出,提供给数量化理论进行计算,并把结果反馈给GIS进行区域滑坡灾害预测图的制作.通过上述方法可以大大提高效率以及灾害预测图的准确度.该方法实际应用于日本熊本县水俣市地区得出的结果,证实提出的方法只需要传统方法所需时间的1/10就可以高精度地完成区域滑坡灾害预测图的分析计算和制作工作.
