摘　　要： 为顺利完成国家农用地分等定级工作,设计开发了农用地分等定级信息系统.系统的设计采用组件式地理信息系统和计算机编程技术,系统的计算原理依据国家农用地分等与定级规程确定.该系统包括数据处理、地图制作、统计分析等7个模块,能迅速实现农用地分等定级的计算,并具有分层分类数据库综合管理功能.系统界面友好,操作简便,可推广性强.该系统已在湖南省农用地分等定级项目中取得较好的应用效果. To accomplish the project of national agricultural land classification and gradation, the information system of agricultural land classification and gradation is devised, the system was originally developed with computer languages and GIS components. The calculation rules of the system depend on Regulations for classification on agricultural land and Regulations for gradation on agricultural land. The system has seven modules including data processor, map fabrication and statistics, etc.. It could do the calculation of agricultural land classification and gradation quickly and has powerful capability of data management as well. The whole system is full of humanity, so it is very easy to learn and operate, which makes it be widely used. The effects of applying the system to Hunan province are satisfactory.
