| 摘 要： | 在GIS环境下应用Logistics回归模型编制地质灾害区划图。针对网格的生成、致灾因子的选择、不重合边界等问题,运用GIS的空间分析功能和SPSS的统计功能,消除了这些问题对滑坡灾害区划图的准确度的影响。结合贵州省的实际,根据历史灾害的分布情况,比较不同方法编制的滑坡灾害敏感性区划图,确定最优编制方法。对基于Logistic回归模型编制滑坡灾害敏感性区划图提出若干指导性建议,丰富和完善了Logistic回归模型编制滑坡灾害区划图方法体系。

| Abstract: | The purpose of this paper is to establish landslide susceptibility map using Logistic Regression.There were some problems which are easily overlooked by researchers,such as how to create fishnet,how to choose the factors and how to eliminate the misaligned borders,when establishing landslides susceptibility mapping with the logistic model based on GIS.These problems were related with the accuracy of the landslides susceptibility map.This paper determined the best way to get landslides susceptibility map of ... |
