摘要
通过对不同温度下的土壤持水特性进行分析,得出含温度因子的土壤特征曲线方程,同时对土壤最大有效含水量与温度的关系进行分析,结果表明土壤最大有效含水量随温度升高而降低。
The equation of soil water retention curve including the temperature factor was established by analyzing the characters of soil water retention at different temperatures, then the relation of temperature to the largest available water capacity in soil(LAWCS) was studied, and the solution is that the higher the temperature, the less the LEWCS.
