目的：利用智能手机和Google Earth的数字化、可视化功能，构建钉螺资料数据库。方法先给智能手机加载多点GPS软件。选择1块江滩查螺，先通过手机端采集调查框的GPS数据，将采集的原始数据以KML/KMZ格式导入计算机，将KML转化为Excel格式，录入实验室检查结果，实现原始螺情资料的数字化。再将Excel格式转化为KML/KMZ格式文件，导入Google Earth进行可视化展示。结果完成1块5 hm2江滩螺情数据采集，获得基于Google Earth的可视化螺情分布图，构建了钉螺资料数据库。通过钉螺资料数据库，可查询每个调查框的钉螺数、活螺数和感染螺数等数据。结论利用智能手机和Google Earth，实现了原始查螺数据的数字化管理。“,”Objective To establish an Oncomelania hupensis snail database based on smartphone and Google Earth. Meth?ods The HEAD GPS software was loaded in the smartphone first. The GPS data of the snails were collected by the smartphone. The original data were exported to the computer with the format of KML/KMZ. Then the data were converted into Excel file for?mat by using some software. Finally the results based on laboratory were filled and the digital snail data were established. The data were converted into KML and then were showed by Google Earth visually. Results The snail data of a 5 hm2?beach along the Yangtze River were collected and the distribution of the snails based on Google Earth was obtained. The database of the snails was built. The query function was implemented about the number of the total snails the living snails and the schistosome infected snails of each survey frame. Conclusion The digital management of the snail data is realized by using the smartphone and Google Earth.
