【摘要】 探讨了小城镇土壤资源管理信息系统的研究和构建:其中包括系统设计目标及流程、系统架构设计和系统功能设计。应用组件式技术,采用流行的组件式GIS开发平台MapObjects与可视化开发语言Visual Basic,以湖北省江陵县为例,设计基于SQL Server 2000和ArcSDE存储管理的小城镇空间数据库和属性数据库,并在此基础上,开发小城镇土壤资源管理信息系统,实现了通用的GIS功能和专业的应用分析功能。系统可为小城镇建设中土壤资源的合理利用与保护提供数据采集、表达和分析支持。通过提供实时服务,提高土地管理工作效率和农技推广水平。更多还原

【Abstract】 The soil resource management information system of small towns was constructed,including the systematic design objectives and flow,systematic design of framework and functions.According to component technology,with Jiangling county of Hubei province as a case,the component GIS development platform of MapObjects and Visual Basic were used to design the spatial databases and attribute databases of small town which could be stored and managed on based on SQL Server 2000 and ArcSDE.The common functions of GIS and analysis functions of professional application are achieved with this information system,in which soil data can be collected,displayed and analyzed.This system can provide decision support for rational use and protection of soil resource in small towns’ construction.更多还原
