摘　　要：[目的]探讨丹江口大坝加高工程实施对汉江中上游区域内斯氏并殖吸虫病分布及流行趋势的影响,为制定防治策略提供科学依据。[方法]区域内采获溪蟹镜检囊蚴,检查动物体内斯氏并殖吸虫的感染情况,收集既往资料与现场肺吸虫抗原和酶联免疫吸附试验调查数据作统计分析人群肺吸虫感染。观察和分析大坝加高后人类行为、局部环境的改变对中间宿主孳生的影响。[结果]大坝加高后环境因素、特别是人类的行为对肺吸虫中间宿主的孳生有较大的影响,局部流行的区域已不具备中间宿主孳生所需的环境,水位的提升可形成更多的溪沟和山涧,有利于螺和溪蟹的孳生。调查显示人群感染率为12.98%,经防治人群肺吸虫和中间宿主囊蚴感染率都有较大幅度降低。[结论]汉江中上游十堰地区作为南水北调水源区,斯氏并殖吸虫在局部范围的孳生环境和流行己发生了一定的变化,动物宿主肺吸虫囊蚴的感染及人群感染呈现逐渐下降趋势。同时随着退耕还林实施,汉江中上游区域生态环境将得到进一步改善,肺吸虫病的疫源地也将会长期存在。[Objective] To understand the distribution and endemic tendency of paragonimusis in Shiyan region after Dangjiang Kou Dam engineering heightened,so as to provide scientific evidences for controlling the disease.[Methods] The data concerning the control of paragonimusis were collected and analyzed.The effect of the environment and human behavior on propagation of the intermediate host of pagomigonimus was observed.The rate of infection of the different host was examined.[Results] The influence of environment factor and human behavior to intermediate host of pagomigonimus was powerful.The infection rates of population（about 12.98%） and intermediate host were reduced by prevention and control measures.[Conclusion] The prevalent areas of paragonimusis are reducing gradually,and the number of infected people is decreasing year by year.With improvement of the propagation environment of the second intermediate host and other wild animals in the region,and the pagomigonimus may exist for a long period.
