Abstract The difference of land surface features and physical characteristics is mainly mechanism that causes anisolropic distribution of albedo. Using statistic models, bidirectional reflectance models and NOAA14-AVHRR data, we retrieve and analyse the monthly mean albedo of 1995. Land-surface cover type obviously change in every year because of (he human activities. This inevitably makes environment modified and often leads to global climate change though the convection of large-scale atmospheric circulation. So, a study of the land suface albedo has important scientific sense.
