| 摘 要： | 浙江省温州市是台风引发斜坡地质灾害高发区。采用灰色关联度法分析该地区此类地质灾害各影响因子的作用程度和因子间关系。研究中以野外调查为基础,结合台风资料构建GIS数据库。结果表明,各因子作用程度量化排序依次为风力、坡度、坡向、岩组结构、降雨、植被、高程、临空面坡角和七级风圈持续时间,风力与其它因子的相关性最强,七级风圈持续时间相关性最弱。

| Abstract: | The method of gray correlation analysis was used to discuss the role of the impact factors of such geological hazards in the region and their relation.A GIS database was established,based on field investigations and typhoon information.The results show that wind force has the greatest effect on slope hazard happenings and the strongest correlation with other factors,while force seven wind ring duration the weakest effect and correlation. |
