Abstract: Objective Objective To establish a monitoring database of historical Oncomelania hupensis environments at grass?root lev? el for schistosomiasis prevention based on Google Earth（GE），so as to improve the management efficiency of historical O. hu? pensis environments. Methods Methods GE was labeled with the information about the historical O. hupensis environments through add? ing landmark，path and polygon. Meanwhile，POCO web album was used to storage the practice situation pictures of the environ? ments，which could be imported into GE so that the environments could be monitored dynamically. Results Results There were 553 historical O. hupensis snail environments in Yangjian Town，Xishan District，Wuxi City and the accumulative area was 506 000 m2 . Among these environments，224（40.5%）were Class IV environments，accounting for 40.5% of accumulative area. Conclu Conclu? ? sions sions The monitoring database of historical O. hupensis environments based on GE at country level is established successfully and it can be used to manage the historical snail environments visually and monitor the changes dynamically.

摘要： 目的 目的 应用谷歌地球 （Google Earth， GE） 建立基层血防历史有螺环境监测数据库， 以提高历史有螺环境管理效 率。方法 方法 在GE软件平台上完成无锡市锡山区羊尖镇历史有螺环境相关信息的标注； 同时通过POCO网络相册将历史 有螺环境现况图片导入GE软件， 实现对环境现况的动态监测和管理。结果 结果 共调查历史有螺环境553个， 面积50.6 hm2 ； 以IV类环境为主， 共224个， 面积20.5 hm2 ， 分别占历史有螺环境环境总数和总面积的40.5%和40.5%。以此为基础， 通过GE软件在乡 （镇） 层面建立了历史有螺环境数据库， 获得了全乡 （镇） 历史有螺环境分布图。结论 结论 利用GE软件易 于实现对历史有螺环境的可视化管理和动态监测， 适合在基层血防机构中推广应用。
