Spatio-temporal Patterns and Statistical Analysis of Surface Albedo in Tibetan Plateau

Based on NOAA/AVHRR data from 1982 to 2000, we have researched the dimensional distribution and change of surface albedo in Tibetan Plateau, researched the relationship between the change of albedo and temperature & precipitation, obtained the statistical relationship between surface albedo and temperature & precipitation, and calculated the distribution and change of surface albedo in Tibetan Plateau by using the regression equation.The results indicated that there were observably difference in the dimensional distribution of annual mean surface albedo in Tibetan Plateau, there were better correlations between surface albedo and temperature lag about one month and precipitation lag about two months;the equation could be better to simulate the spatial distribution and seasonal variation of regional surface albedo in Tibetan Plateau, the statistical indices suggested that the equation possessed a small deviation and a perfect simulate.
