摘　　要：研究目的:研制基于遥感的土地基础分类体系及其土地基础产品的方法和内容,满足不同部门土地利用/土地覆被产品的需求,实现资源共享。研究方法:文献资料法、对比分析法、决策树方法和集合运算方法。研究结果:在阐述和分析现有国家、行业等分类体系模式及存在问题的基础上,提出了一种针对不同目的、不同遥感数据源的基础分类体系和土地信息基础产品——基元产品的研究方法,建立了初级阶段的基元分类体系,并与其他分类体系进行了转换,得到较好的结果。研究结论:土地基元产品能够同时满足不同行业部门应用需要,为中国土地分类领域的研究提供了一种新的思路和方法。The purpose of this study is to develop a method for land basic classification system and analyze the content of the basic products of land via remote sensing. The study can serve as a reference for achieving information sharing among different users regarding the land use /land cover change. Methods used include documentation, comparative analysis, decision tree analysis, and integrated calculation. On the basis of interpreting and analyzing the different patterns and problems of land classification of current national and industrial standards, the paper develops a new method, i.e., a basal classify system, and further develops a land information product that can be applicable to different purposes and different remote sensing data sources. A basic element classification system was established on its initial stage. It can be well converted to and from other types of classification system. The paper concludes that the basic element products of land based on remote sensing not only satisfies different users, but also provides a new idea and method for land classification.
