摘　　要：本文将地理国情地表覆盖数据与美国地质调查局(USGS)、马里兰大学(UMD)、波士顿大学(BU)及欧洲空间局(GLOBCOV ER)等4类遥感全球地表覆盖产品中国区数据进行比较,选取青海省和黑龙江省内两个有代表性的区域进行数据匹配、计算与分析,从数据精度、分类体系、时间信息几方面论述地理国情数据与全球地表覆盖产品的差异与关联规律,从而对上述数据的特性、优缺点及其适用范围进行讨论与评价。In this paper, the data of China National Geographical Conditions Census and China＇s zonal data of remote sensing global land cover products from USGS, The University of Maryland （UMD）, Boston University （BU） and ESA＇s GLOBCOVER in China were compared. Selecting two representative regions in Qinghai and Heilongjiang province of China, the authors applied data matching, calculation and analysis to the census data and the global land cover products, in order to define the relationship and differences among their accuracy, classification systems and the time information. As a result, the characteristics, applications, advantages and disadvantages of the census data and the global land cover products are discussed and evaluated.
