| Abstract: | In this paper, the annual aridity was calculated with Penman Evaporation Formula improved and revised in China. According to indexes of Chinese Soil Taxo nomy , the soil moisture regime was also estimated. Results show that 3 soil moisture regime districts and 6 sub districts can be divided tentatively in China. |
