基于MODIS数据设计的中国土地覆盖分类系统与应用研究

Design of land cover classification system for China and its application research based on MODIS data

该文阐述了国内外主要土地覆盖分类系统及其土地覆盖产品在中国的表现，依据中国植被编码体系在MODIS数据试验的基础上，对现有国内土地覆盖分类系统进行了重新设计，包括7大类22个二级类别，并利用2001～2002年MODISlkm时间序列NDVI数据和多波段反射率光谱数据对中国区域进行了土地覆盖分类，结果显示分类产品能较为准确地描述中国区域土地覆盖的实际情况。

Expatiated on the domestic and foreign main land cover classifications and products in China＇s performance. A new land cover classification system from MODIS data which includes seven first-degree types and twenty-two second-degree types was designed based on Chinese Vegetation Code System. Multi-temporary NDVI and multi-spectrum reflectance from MODIS lkm data in 2001～2002 were used to map land cover of China. The result showed that the classification product was close to China land cover fact.
