洪涝灾害因其发生频率高、损失大而受到世界各国的普遍关注。今天，中国在防洪减灾方面取得了巨大成就。洪水风险分析在非工程措施中占有非常重要的地位。洪水风险分析方法经历了从DI（直接积分）法、MC（蒙特卡罗）法、MFOSM（平均一阶二阶矩）法、SO（二阶矩）法到AFOSM（先进一阶二阶矩）法、JC法等的发展历程。建议：(1)明确和统一风险分析的内涵；(2)开展“风险分析的风险”研究；(3)引入和推进风险分析的基本理论和方法，如熵理论、模糊信息优化技术等。中国东南中生代地质事件与太平洋俯冲作用王飞云，孙卫东*，凌明贤，丁晓东，杨晓东。中国科学院广州地球化学研究所，510640合肥230026（*通信：weidongsun@gig.ac.cn）
Flood & waterlog disaster catch the worldwide special attention because of its frequent happening and greatest loss. Great achievements have been gained in flood control and disaster decrease in China today. Flood risk analysis occupies a very important position in non-engineering measures. The flood risk analysis methods has shown a progress from DI (Direct Integral) method, MC (Monte Carlo) method, MFOSM (Mean First Order Second Moment) method and SO(Second Order) method, to AFOSM (Advanced First Order Second Moment) method, JC method, etc. The expectations are suggested: (1) To make the connotation of risk analysis clearly and unified; (2) To carry out risk of risk analysis research; (3) To introduce and advance the basic theory and methods into risk analysis, such as the entropy theory, fuzzy information optimization technology and so on.
