| 摘 要： | 山洪及其诱发的泥石流、崩塌、滑坡等灾害突发性强、危害大，应根据区域灾害风险分析的结果，对潜在高风险区进行重点防护。本文在分析灾害成因和风险因素的基础上，采用指标模型法，基于地理信息系统技术对桂东县寨前流域内山洪及其诱发灾害的风险进行了分析，得出灾害高风险区的分布。

| Abstract: | The disasters of torrent and concomitant muddy flow, dilapidation, landslide usually erupt suddenly and result in huge damages. Therefore, it is very important to take precaution measures to the zones with high potential risk from disasters according to the risk analysis. Based on the causes of disaster formation and risk factors, this paper used the technology of geographic information system to analyze qualitatively the risk of torrent and concomitant mud flow, dilapidation, landslide and got the distribution of high risk zones. |

| Keywords: | geographic information system torrent disaster slope dilapidation risk analysis |
