[Objective]An overall design of farmland soil testing and formulated fertilization management system was developed in order to practice precise fertilization and for sustainable development of agriculture. [Method]System structure, function module and database of farmland soil testing and formulated fertilization were designed in accordance with technical features of WebGIS and practical demand of fertilization. [ Result ]Three-layer B/S network system was used to realize six main functions: map search, information search, statistics analysis, recommended fertilization, output & printing as well as system maintenance & management. The database was composed of two parts: spatial database and non-spatial database. [Conclusion]This system can provide accurate and scientific fertilization information and guidance to farmer, enhance soil nutrition management and fertilizer efficiency, reduce agricultural environmental pollution, and promote sustainable development of agriculture.%[目的]对基于WebGIS的农田测土配方施肥管理系统进行总体设计,为该系统的开发与实现奠定框架基础,从而实现农田精准施肥,促进农业可持续发展.[方法]根据WebGIS技术特点及农田测土配方施肥实际需要,对农田测土配方施肥管理系统的体系结构、总体功能结构和数据库进行设计.[结果]系统采用B/S三层体系结构,具有地图基本操作、信息查询、统计分析、推荐施肥、打印输出、系统维护和管理等六大功能,数据库由空间数据库和非空间数据库组成.[结论]基于WebGIS的农田测土配方施肥管理系统可为用户提供准确、科学的施肥指导信息服务,提高土壤养分管理技术和肥料使用效率,减少农业环境污染,促进农业可持续发展.
