摘要
根据农用地分等定级与估价的基本原理和方法,以ComGIS为系统开发平台,利用UML技术,从系统整体设计入手,提出了采用多层次用例描述法建立农用地分等定级与估价信息系统(ALEIS)用例模型的过程,在此基础上介绍了ALEIS设计、编码与测试,最后提出了ALEIS的特点与发展趋势。在农用地分等定级与估价信息系统开发过程中,利用UML对系统进行建模分析能够取得较好的效果。
Based on principle of classification, graduation and evaluation on cultivated land and technology of composite geography in formation system （ComGIS） and Unified Modeling Language （UML）, cultivated land classification, graduation and evaluation information system （ALEIS） were designed and implemented. After designing system unitary structure, the process of setting up use-case models by using multil-layer use-case modeling is introduced. Then system analysis, program and testing, system characteristic and direction were presented. The results indicate that it can obtain favorable effect by using UML in the process of developing cultivated land classi fication, graduation and evaluation information system （ALEIS）.
