摘　　要：通过监测泳季大连海水浴场中指示细菌——肠球菌浓度,应用定量微生物风险评价(Quantitative microbial risk assessment,QMRA)评估游泳人群患胃肠道疾病的潜在风险.结果显示,旅游季节大连市内海水浴场男人、女人和儿童的风险分别为24.09‰、17.46‰和29.76‰,其中男人和儿童的娱乐风险已经超出了EPA规定的可接受日娱乐风险(19‰).涨潮、降雨12 h内、游泳人群过于密集都将增加海水浴场娱乐者的潜在娱乐健康风险,涨潮情况下潜在感染风险约为落潮的8倍,雨后3种人群的平均潜在感染风险约为雨前的20倍.因此有必要进行海水浴场的人体健康风险评估工作,本研究可为未来海水浴场健康风险预测和有效管理提供研究基础和科学依据.Quantitative microbial risk assessment method （QMRA） has been widely used to analyze health risks for recreational activities at bathing beaches in western countries. However, QMRA is still scarcely used in assessing health risk of bacterial index in China. This research evaluated human health risk by using Enterococcus at bathing beaches in Dalian, China. Results showed that the average risk probabilities for men, women and children were 24.09‰, 17.46‰ and 29.76‰ respectively during the tourist season in Dalian. The recreational risk for men and children exceeded the acceptable threshold set by EPA （i.e. 19‰）. Data obtained in this study indicated that tidal condition, rainfall and people density were the three major contributing factors that could increase health risk. This research suggests that it is quite necessary to evaluate heath risk for recreational people at marine bathing beaches, which can reduce the health risk for people during recreational activities.
