摘要
本文从建立沙漠化环境信息系统的核心问题——专题图形库为出发点，对建立沙漠化环境信息系统的图形自动扫描矢量化、图形快速编辑、图形网络通讯及图形库定量研究等问题作了较详细的研究探讨；提出了一套可用于快速建立沙漠化环境信息系统的理论与技术体系，并以此为基础建立了科尔沁典型沙区土地类型三个时期两级专题图形库，对该区进行了示例性分析，获得了该区三十多年来的动态演变信息。该研究方法对我国沙漠化的定量研究及决策治理具有重要意义。
With consideing the core problem--the thematic cartographic data base,which was used to establish the desertification environment information system,this paper has done a more careful research and discuss of the graphics autovectorization,the graphics fast editing,the graphics network communication and the cartographic data base quantitative research,etc,gives a theory and technology architecture which was used to establish the desertification environment infomation system.Based on this architecture,it establishes a two classes land type thematic cartographic data base of three periods in Horqin typical sandy area.From the example analysis,we obtain the dynamic varying infomation of the area in the more than thirty years.The research method will have an important meaning for the desertification quantitative research. \ \
