Abstract:

According to the practical requirements of farmland, including realtime and movement on data acquisition, the paper designs and develops a farmland information management system based on GIS, which includs farmland attribute data management module, agricultural production operation management module and farming operation management module supported by GIS technology. The system database is developed by Microsoft SQL Server 2005, and the server software is developed by C#. The mobile server uses VS2005 environment and browser is developed based on XHTML and JavaScript. In the farmland data management module, the system has the functions of data acquisition, data export, attribute query, data statistical analysis and layer editor. With the support of commercial communications, operators can obtain information of farmland data or farm work by using smart phone or PDA in this system and then send the data to the server. Managers can use remote operation in their office. The system can provide more systematic and effective services for plots with research, teaching, production and other functions.

摘要：

根据农田的实际操作要求，包括对数据采集的实时与移动等，设计开发了一套基于GIS的农田信息管理系统。系统以GIS技术为支撑，包括农田属性数据管理模块、农资操作管理模块、农事操作管理模块等。系统数据库采用Microsoft SQL Server 2005，服务器端采用C#语言开发，移动客户端使用VS2005环境，浏览器端基于XHTML与JavaScript。在农田数据管理模块中，系统具有数据获取、数据导出、属性查询、数据统计分析、涂层编辑等功能。在商业通信运营商的支持下，操作员在田间利用智能手机或PDA使用系统获取田间数据或者田间作业相关信息，最后传送给系统服务器，管理人员可以在办公室进行远程操作。该系统可为具有科研、教学、生产等功能为主的试验田提供系统有效的服务。
