摘要
根据改进的彭曼公式估算出的年干燥度,依据《中国土壤系统分类(修订方案)》中有关土壤水分状况的定量诊断指标,对我国的土壤水分状况进行估算,初步将我国划分为3个土壤水分区,6个土壤水分亚区。
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.
