摘　　要：随着环境风险评估的重点由单一源、单一传播途径、单受体转向多来源、多传播途径、多受体的评估,累积性环境风险评估逐渐成为当前研究热点。通过概念辨析和文献调研的方法,综述了美国累积性环境风险评估的发展历史、评估流程,并对国内外累积性环境风险评估方法、应用研究进展进行了评述。指出了目前国内开展累积性环境风险评估存在的方法不完善、基础科研工作不足、宏观环境管理政策亟待加强等问题。建议应尽快明确累积性环境风险评估概念与管理要求,制订累积性环境风险评估的流程、框架与技术指南,加强基础数据库建立和实践探索,为长效的环境风险管理提供决策依据。With the focuses of environmental risk assessment gradually evolving from assessment of single source or stressor, single exposure route and single risk receptor toward integrated assessment involving several sources or stressors, multiple exposure routes and multiple receptors in recent years, the cumulative risk assessment has become a study hot spot. Through concepts discrimination and literatures search, the development history and assessment procedure in the US, and the methods and practices of cumulative risk assessment both at home and abroad were reviewed. It was pointed out that there were several problems in conducting cumulative risk assessment in China, such as lack of assessment methods, lack of basic scientific data and urgent need of reinforcement of macro-environmental management policy and so on. It was suggests that the concept and management requirements of cumulative environmental risk assessment should be defined, the evaluation process, framework and technical guide be formulated, and the construction of foundational databases and practical explorations be reinforced as soon as possible, which can provide the decision support for the long-term effective environmental management.
