摘　　要：地质灾害风险，是指地质灾害活动及其对人类生命财产造成破坏损失的可能。地质灾害风险具有必然性、随机性、模糊性、不均衡性等特点。按地质灾害风险评价区域范围，分为点评价、面评价、区域评价。基本内容包括危险性评价、易损性评价、破坏损失评价、防治工程评价，由此构成多层次的评价系统。地质灾害风险评价采用系统工程思想和层次分析、相关分析、模糊聚类分析、工程分析、经济分析，以及指数法、定数法、概率法、资产评估方法等进行研究。目前，地质灾害风险评价刚刚兴起，今后随着理论方法的不断丰富和完善，以及计算机技术的广泛应用，地质灾害风险评价将进一步向模型化、定量化发展，成果应用范围将更加广泛。The risk of geological hazards is referred to as the resulted damage to man's lives and properties.It is characterized by being inevitable,random, fuzzy and uneven.It can be evaluated by using the thought of systematic engineering and in many ways like correlation analysis,fuzzy cluster analysis, project analysis,economic analysis,probability and assets assessment etc.The evaluation of the risk of geological hazards is just a newly risen subject.In the future it will be developed further in modelling and quantization with the development of theory and application of computer techniques.The results received would be applied more widly.
