摘　　要：充分调查了广西(桂林)园林园艺博览园建设项目,认定评估区内可能发生的地质灾害类型为崩塌滑坡、岩溶塌陷和地(路)基不均匀沉降等。针对每一灾种,判定各自的影响因素,并对各影响因素进行排序,选取影响大的因素为优先考虑对象,同时参照相关文献资料和实际工作经验,制定评判标准。运用模糊数学理论,对建设项目进行模型运算和隶属度分析,将评估区分为大、中、小、微弱四个级别,阐明各级别所属区域的特征,建立区域地质灾害危险性评价体系,确定建设场地的地质灾害危险性程度,为工程设计、施工提供参考。Based on the full-scale investigation in relation Landscape Gardening Exposition Park, it was identified to the construction project of Guangxi （Guilin） that landslide and karst collapse, and uneven settlement of foundation （subgrade） are the geological disasters that may occur in this area. For each kind of disaster, the respective affecting factors were determined, and then sequenced; then the factor that has large impact was selected as the object with priority and, depending on related references and experiences, the assessment standard was specified. Based on fuzzy mathematics theory, the model calculation and membership analysis on account of the construction project were conducted, by which the area was ranked as large-, medium-, small-and weak-level with the regional characteristics of each level explained. Therefore, the risk assessment system for regional geological disasters was established and the degree of the geological hazard on the construction site confirmed, offering the basis in decision-making for safe construction.
