Abstract: Objective To grasp the status of Oncomelania hupensis snail?infested environments in schistosomiasis endemic areas of Jiangxi Province， and establish the spatial database of snail?infested environments with the administrative village as the unit. Methods The spatial and temporal distributions of the historical snail environments， existing snail environments， and suspicious snail?infested environments were analyzed by the historical data review and field investigations. Results The distribution of snail?infested environments in Jiangxi Province included two popular types of lakeshore and hills. The O. hupensis snail?infested environments were mainly concentrated in the Poyang Lake area， which accounting for 66.97% of the total snail?infested areas. The potential snail?infested environment area was 204 745.48 hm2， among which the potential snail?infested environment areas in the lakeshore and hills were 146 548.58 hm2 and 58 196.90 hm2， accounting for 71.58% and 28.42%， respectively. The real existing snail area was 83 234.50 hm2， among which the real existing snail areas in the lakeshore and hills were 80 890.81 hm2 and 2 343.69 hm2， accounting for 97.18% and 2.82%， respectively. The compressed snail area was 114 253.30 hm2 with a compression rate of 57.85%， of which the compression rates in the lakeshore and hills were 46.51% and 94.97%， respectively. In the four types of snail?infested environments， the areas of Type Ⅰ， Type Ⅱ， Type Ⅲ and Type Ⅳ accounted for 55.77%， 25.75%， 13.91% and 4.57% of the total area， respectively. Conclusion The spatial database of O. hupensis snail?infested environments is established comprehensively and systematically， that will be conducive to tracking and performing the dynamic updates of the data of snails， so as to provide an important technical support for investigation and monitoring in the future.

摘要： 目的 掌握江西省钉螺孳生环境时空分布特征，建立以行政村为单位的钉螺孳生地数据库和环境空间数据库。方法 采用查阅资料和现场调查相结合的方法，分析全省历史有螺环境、现有螺环境和可疑钉螺孳生环境时空分布。结果 江西省钉螺孳生环境有湖沼型和山丘型两种类型，主要集中在鄱阳湖区，占总孳生地面积的66.97%。现有潜在钉螺孳生环境204 745.48 hm2，其中湖沼型和山丘型分别为146 548.58 hm2和58 196.90 hm2，分别占71.58%和28.42%；实际有螺面积83 234.50 hm2，其中湖沼型和山丘型分别为80 890.81 hm2和2 343.69 hm2，分别占97.18%和2.82%；压缩有螺面积114 253.30 hm2，有螺面积压缩率为57.85%，其中湖沼型和山丘型有螺面积压缩率分别为46.51%和94.97%；Ⅰ、Ⅱ、Ⅲ类环境和Ⅳ类环境分别占总有螺面积的55.77%、25.75%、13.91%和4.57%。结论 全面、系统地建立了江西省钉螺孳生地数据库和环境空间数据库，实现了对各地钉螺孳生环境螺情、环境和植被情况的动态更新与追踪管理，可为螺情监测提供支撑。
