摘要
滑坡灾害严重影响社会经济的发展,以陕南地区为研究对象,采集滑坡灾害点最近区域站逐小时和前期综合雨量,使用SVM算法,选择合适的决策函数,以不同时段降雨为特征对滑坡灾害点进行两次分类。分析降雨对滑坡灾害的影响,为地区降雨型滑坡灾害研究提供依据。
Landslide disaster seriously affects social and economic development, the southern part of Shaanxi as the research object, Hourly and pre-integrated rainfall is collected at the nearest regional station at the landslide hazard point, SVM algorithm is used, the appropriate decision function is selected,landslide hazard points are divided into two categories based on rainfall during different periods. The basis for the study is provided as a regional rainfall landslide disaster to analysis of the impact of rainfall on landslide disasters.
