| 摘 要： | 本文以桂林国家高新区苏桥园B区地质灾害分布密度、岩土体性质和结构、地形坡度、植被覆盖率、人为活动强度、岩溶发育程度、覆盖层厚度和性质、地下水变幅、所处地质构造部位、对建（构）筑物及道路的破坏程度、填方厚度和用地类型等18个影响环境地质要素作为评判因子,应用模糊综合评判原理与方法,通过模型运算和隶属度分析,将桂林国家高新区苏桥园B区地质灾害危险性分为大、中、小和微弱四个等级区,并就地质灾害危险性分区特征及主要环境地质问题进行了评述。

| Abstract: | The risk of the geological hazard evaluation system and model were established, which was based on the 18 factors including density of geological disaster, rock-soil characteristic and structure, the gradient o~ the landform, the ratio of the vegetation cover, human activities, karst development, range of groundwater ceel fluctuation, geologic structure condition, destructive degree of building and road, fill thickness and purpose of land etc. The region was divided into four zones, as big, medium, small, and faint, respectively. Moreover, the developmental characteristics and harming degrees of environmental geologic events affecting the environmental geologic quality in each zone were also stated. |
