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。 Wenzhou City, Zhejiang Province, is a high incidence area of ​​geological disasters caused by typhoon. Gray relational degree method was used to analyze the relationship between the degree of influence factors and the factors of such geological disasters in this area. Based on the field survey and typhoon data, GIS database was constructed. The results show that the order of quantification of each factor is the order of wind force, slope, aspect, rock group structure, rainfall, vegetation, elevation, slope face angle and the duration of the seventh air ring. The correlation between wind power and other factors is the strongest , Seven air ring duration of the weakest.
