摘　　要： 土地覆盖变化是全球变化研究中的一个重要内容,而建立一个标准的土地覆盖分类系统又是研究土地覆盖变化的重要前提,它影响分类结果的表达形式,决定土地覆盖数据的应用领域。文章对国内外的土地覆盖分类系统的研究进展和主要的分类系统进行了论述,指出目前分类系统一般都适用于特定的数据类型和研究目的,全球的土地覆盖分类没有一个统一的标准。这种土地覆盖分类系统的不兼容性,给土地覆盖数据的汇总、分析及信息共享工作带来了很多不便。因此迫切需要建立一个标准的分类系统,使分类系统所定义的类别不受尺度和数据资料来源的限制,能够灵活地应用于不同的研究目的和研究领域。 Changes of land vegetation is one of the important contents for research on global changes, while establishing a standard land vegetation classification system is an important precondition for the research on changes of land vegetation. It can influence the expressive method of classification result; determine the application areas of data of land vegetation. This paper expounds the internal and external progresses made in the research on land vegetation classification system as well as on the major classification systems. This paper also points out that the present classification systems are generally suitable for using by specific data type and research objectives. There is not a unified standard for global land vegetation classification. This land vegetation classification system has no compatibility, and has brought many inconveniences in collecting, analyzing and sharing information. Therefore, it is an urgent need to establish a standard classification system and to make the types defined by the system without limitation in measurements and resources of data ＆ information. Thus the system can be used flexibly in all research areas with different research objectives.
