权重线性组合与逻辑回归模型在滑坡易发性区划中的应用与比较
Application and comparison of weighted linear combination model and logistic regression model in landslide susceptibility mapping
摘要
Abstract
Taking Guizhou Province as an example, the landslide susceptibility mapping was assessed, and a comprehensive comparison of the two approaches was conducted. The procedures are as follows. Firstly, a total of ten landslide triggering factors including average annual precipitation, lithology, elevation, aspect, topography, slope, proximity to structural lines, proximity to drainage network, proximity to railways and proximity to roads were considered. The weighted linear combination (WLC) model and logistic regression (LR) model were applied to investigate the correlation between the presence or absence of landslides and the set of triggering factors, and then the prediction models were produced respectively. Secondly, two landslide susceptibility maps were produced in ArcGIS environment The zonation results derived from the two models were verified using the past failures and compared using the entropy method. At last, the two models were compared and discussed in terms of their principles, operating environments and applicable conditions. The results show that the entropy for WLC and LR model are 0.255 and 0.745, respectively, indicating that the LR model has better performance than the WLC model.关键词
