dc.description Based on the NOAA-AVHRR data during from 1982 to 1998, we have researched the relations among surface albedo, temperature and precipitation. The results indicated that there was observable difference in the dimensional distribution of mean surface albedo, and the change trends of albedo were not the same in different areas. There were better correlations between surface albedo and temperature & precipitation;there was no lag between surface albedo and temperature & precipitation in northeast of China, the correlation coefficients were 0.732 and 0.631 respectively, but it was lag about one month in Qinghai-Xizang Plateau, the correlation coefficients wer 0.574 and 0.436 respectively, and two months in Huabei Plain, the correlation coefficients were 0.349 and 0.282 respectively. The reason for the increase of annual mean surface albedo in northeast of China was the climate change trends that it became hotter and arider in summer, the precipitation was increased in spring leading to the decrease of the annual mean surface albedo in Huabei Plain, it was because the temperature in cold season was decreased so the annual mean surface albedo was increased.
