| 摘 要： | 利用安徽省长江以北地区干旱时段降水量和土壤墒情资料，分析在不同的地区、季节、干旱程度状况下各降水量等级对土壤水分变化的影响。根据安徽省的实际情况调整了干旱判别标准，分别建立了相应的土壤墒情变化模型，并对典型干旱年进行了实况分析，得出了降水对我省江北地区土壤水分演变趋势影响的一些规律。

| Abstract: | Influence of rainfall at varying level on the change of soil water was analyzed by the data of rainfall and soil water in dry period in North of the Yangtze River of Anhui, under different conditions of districts, seasons, degrees of drought. Models response to the relationship between rainfall and soil water conditions was established and truth of typical dry years was analyzed. Then, some laws of precipitation on soil water change was achieved, which provides quantitative basis for making policy to economical irrigation. |
