摘要利用高分辨率卫星遥感数据计算了归一化植被指数（NVI）和植被覆盖度。通过叠加详细数字信息，分析了其对应土地利用的频率分布特征。在10米网格的原始数据所产生的频率分布进行比较，这些平均数据在每10米网格，这似乎代表了流行的课程分辨率卫星遥感数据。通过使用这些高分辨率的数据与地理信息系统，建筑物的屋顶和道路的重叠似乎是区分。研究了不同土地利用类型的NVI和NVDO的频率分布特征，发现4m网格原始值的频率分布特征与10m网格平均值的频率分布特征基本相似。但在某些土地利用类别中，类别中所包含的土地覆被的具体材料会扩大标准差。
abstract Normalized vegetation index (NVI) and albedo are computed using the fine resolution satellite remote sensing data. The characteristics on their frequency distributions for corresponding land uses are analyzed by superimposing the Detailed Digital Information on them. The frequency distributions generated by raw data in 10m meshes under consideration are compared to these made by the averaged data in each 10m meshes which seems to represent the popular course resolution satellite remote sensing data. By using these fine resolution data together with the GIS, albedo of the building roofs and roads seem to be distinguished. The characteristics on the frequency distributions of NVI and albedo for individual land uses are examined, and these for the raw value of 4m mesh are shown to be almost similar to those for the averaged value in 10m mesh. However in some land use categories, the specific materials of land cover contained in the categories are found to enlarge the standard deviation.
