目的：调查与分析江宁丘陵型血吸虫病流行区钉螺分布特点，为本地区制订实现血吸虫病传播阻断目标的策略和措施提供参考依据。方法采取回顾性调查方法，收集江宁区2004~2013年血吸虫病防治工作报表资料，分析不同年份钉螺面积的变化趋势，比较丘陵型血吸虫病流行区钉螺指标的10年间变化。结果江宁丘陵地区历史有螺面积760.46hm2，2004~2013年江宁丘陵地区查出有螺面积从2004年的23.38hm2减少到10.30hm2，平均年降幅为5.59%，平均钉螺密度从2004年的0.74只/框下降到2013年的0.03只/框，无阳性钉螺，新发现螺点1处，有2处钉螺复现，总面积0.56hm2。结论江宁山区钉螺面积、钉螺密度呈下降趋势，为达到实现血吸虫病传播阻断目标，控制山区型钉螺面积仍是下阶段血防工作的重点。

Objective To investigate and analyze the characteristics of Oncomelania hupensis distribution in the hilly and mountain areas in Jiangning district for the evidence to plan the strategy for transmission inter?ruption in this area. Methods Retrospective analysis was performed on the data summarized from the work re?ports on schistosomiasis control in Jiangning district between 2004 and 2013, with respect to the changes of in?fected areas with snails in different years and the snail index in mountainous endemic region in 10 years. Re?sults The snail-ridden areas in the hilly mountain areas in Jiangning district were 760.4562 hm2 in history, and were decreased from . The areas were decreased gradually, from 23.3765hm2 in 2004 to 10.3025hm2 in 2013, and the average annual decline was 5.59%. The average density of snails was decreased from 23.38hm2 in 2004 to 10.30hm2 in 2013, with an average decrease of 5.59% by each year. Snail density was also decreased from 0.7362 snail/frame in 2004 to 0.03 snail/frame in 2013. No infected snails were found except for one emerging snail region and two reemerging snail regions, which only amounted to a total area of 0.56hm2. Con?clusion Snail infected area and snail density tend to decline in the hilly mountain areas in Jiangning district. In order to achieve the target of transmission interruption, following control of schistosomiasis should be focused on these area.
