Abstract: Objective To study the application of Geographic Information System （GIS） electronic fence technique in Oncomelania hupensis snail monitoring. Methods The electronic fence was set around the history and existing snail environments in the electronic map， the information about snail monitoring and controlling was linked to the electronic fence， and the snail monitoring information system was established on these bases. The monitoring information was input through the computer and smart phone. Results The electronic fence around the history and existing snail environments was set in the electronic map （Baidu map）， and the snail monitoring information system and smart phone APP were established. The monitoring information was input and upload real?time， and the snail monitoring information was demonstrated in real time on Baidu map. Conclusion By using the electronic fence technology based on GIS， the unique "environment electronic archives" for each snail monitoring environment can be established in the electronic map， and real?time， dynamic monitoring and visual management can be realized.

摘要： 目的 研究GIS电子围栏技术在钉螺监测中的应用。 方法 在电子地图中沿历史有钉螺、现有钉螺等环境周边划定电子围栏，电子围栏设定需关联此环境查灭钉螺等相关监测信息，在此基础上建立钉螺监测信息系统，并通过电脑、智能手机等监测终端录入监测信息。 结果 在电子地图（百度地图）上完成历史有螺、现有螺等环境电子围栏设定，建立钉螺监测信息系统及手机APP的开发，监测信息实时录入、上传；并在百度地图上实时、直观展现钉螺监测情况。结论 GIS电子围栏技术可实现在电子地图中为各钉螺监测环境建立唯一 “环境电子档案”，并实现实时、动态监测和可视化管理。
