基于WebGIS的农产品产地安全信息管理系统设计与实现

Designing and Establishment of a Safety Information Management System for Agricultural Production Areas Based on WebGIS

以江苏省高风险农产品产地安全信息管理为例,针对农产品产地安全信息的数据特征以及管理决策需要,提出了一种基于WebGIS技术的农产品产地安全信息管理系统设计方案,对系统的设计目标、主要任务、系统结构、数据库结构和主要功能进行探讨。根据系统的主要任务设计了地图浏览、数据查询、数据统计、产地监测信息管理和产地适宜性信息管理5类功能;系统采用客户层、中间业务处理层和服务器数据层3层体系结构;系统数据库设计为索引表、属性表和数据表3层结构;采用C#程序语言和MapXtreme开发平台对系统进行了初步开发与实施。

A case study was conducted of the safety information management of agricultural produce from farmlands high in safety risk in Jiangsu Province. The main objectives of the study were to set forth a design scheme for establishment of a produce safety information management system for agricultural production areas using WebGIS technology in light of data characteristics of the safety information of agricultural production areas and requirements of decision-making in this field, and to explore targets, missions, structure, database and functions of this information management system. According to the missions of the system, five functions, including map browse, query and pivot, data statistics, management of farm- land environment monitoring information and management of farmland suitability information, were designed. The system adopted a three-tier structure, consisting of a client tier, an intermediary business processing tier and a database server tier. According to the principal features of the environment information of the production areas high in safety risk in Jiangsu Province, the system database was also designed to have three layers structure, including index tables, attribute lists and data sheets. And C# and MapXtreme was used as the platform for primary development and running of the system.
