水循环模型

 

(1)蒸发子模型:

              

式中,m为年内月序号;Nm为各月与日照有关的调整因子;Tm为月平均温度;I为年热量指标。

(2)土壤水分子模型:        

           

式中,fi P-PESMCL)表示当降水量小于蒸发量(P-PEi<0)并且土壤含水量小于土壤持水量(STi<SMC)时,土壤含水量STi是降水量与蒸发潜力之差(P-PE),土壤持水能力SMC和土壤特征曲线L的函数;STi-1+P-PEi表示当降水量大于蒸发量(P-PEi>0)并且土壤含水量小于土壤持水量(STi<SMC)时,土壤含水量STi等于前期土壤含水量STi-1加上降水量与蒸发潜力之差(P-PE);STi-1+Pi表示当降水量大于0而温度小于0Pi>0Ti<0)时,土壤含水量STi等于前期土壤含水量STi-1加上降水量(Pi)。
