基于组件GIS的广东省农用地分等汇总管理系统设计与实现

Research on design and implementation method of Guangdong farmland classification and gathering management system based on component GIS

农用地分等定级与估价工作是土地资源调查与评价的一项重要内容，广东省农用地分等汇总成果数据量达IOGB，如何高效地管理并应用这些数据成果，成为农用地分等汇总工作中必须攻克的一道难题．传统的图纸管理方法已不能满足现代应用的要求，为有效利用农用地分等汇总的成果，建立稳定、高效、强大的农用地分等汇总管理地理信息系统具有重要的意义．文章介绍广东省农用地分等汇总成果数据的基本情况，基于组件GIS开发方法建立广东省农用地分等汇总信息管理系统，从架构与功能实现上对广东省分等汇总成果进行无逢集成管理．

Farmland classification and assessment is an important part of land resources survey and evaluation. The datum quantity of farmland classification and gathering of Guangdong Province reach 10GB. How to manage and utilize these data efficiently has become a difficult problem of farmland classification and gathering. Tradi- tional way of managing data has been incapable of meeting the need of modern application. There is great sense to utilize the fruit of farmland classification and gathering, establishing a stable, efficient and powerful farmland classification fruit management information system. In this paper, we introduce the basic instance of Guangdong Province farmland classification data, establish the Guangdong farmland classification and gathering information system based on component GIS. It manages the classification and gathering fruit in frame and function. We also analyze the practicability and efficiency of the system.
