摘　　要：全球环境变化需要精确和最新的区域到全球尺度的土地覆盖数据集以支撑生态系统评估、生物多样性保护、气候变化研究和环境建模。然而,在土地覆盖分类数据集建立过程中,建立科学标准的分类系统至关重要,它影响着数据产品的集成与共享,数据的应用领域与范围。通过对区域尺度、全球尺度及可扩展的FAO土地覆盖分类系统进行评述,指出:①目前国内外没有普遍认可并广泛应用的标准土地覆盖分类系统,这种分类系统的非标准化影响了数据产品的应用以及对土地覆盖变化的监测;②复合特征是土地覆盖的固有属性,有效地表达与特征量化复合类型是需要不断努力去解决的问题;③我国迫切需要建立一套标准的土地覆盖分类系统,一方面能够与国际土地覆盖产品接轨,另一方面充分体现我国的自然环境特征。The global environmental change research community requires accurate and up-to-date land cover dataset to support ecosystem assessment,biodiversity conservation,climate change and environmental modeling.It is important to establish a scientific standard classification system when we develop land cover datasets,because it can influence the integration and share of data products,as well as the application areas of the products.This paper expounds the progress of land cover classification system made in regional and global scales,as well as FAO land cover classification system.It also pointed out：① There is no unified standard classification system so far,which effects the application of data products and the detection of land cover change;② Mosaic feature is the inherent characteristic of earth surface,we should make great effort to express effectively and quantify feature of mosaic types;③ It＇s urgent to develop a standard land cover classification system in China which can＇t only be consistent with global land cover products,but also reflect the natural environmental condition of China.
