土壤覆盖热效应分析公式

(1) 覆盖土壤的热量平衡方程为:

式中,R是净辐射通量;为覆盖物外表面与近地空气层的显热交换,是土壤表面温度,是距地面高度z处的温度,为空气的水汽扩散系数;为覆盖物外表面与近地空气层的潜热交换,是干湿表常数,为水汽扩散系数,是土壤表面的水汽压,是距地面高度z处的水汽压;为覆盖物上下表面之间的热传导;为空气层内的热交换;为地表与土壤内部的热交换。

(2) 基本热传导方程:

式中,T为土壤温度;为时间;x为土壤深度;k为土壤导温系数。

(3) 下垫表面的辐射平衡方程是:

式中,α为下垫面的反射率;Q为太阳总辐射;A是下垫面的有效辐射。

(4) 影响覆盖地温度变化的微气象条件分析公式:

式中,表示当地表从太阳辐射所得的能量;Q/β表示,如果下垫面和近地空气层是一黑体系统(α=0),同时下垫面又没有其他任何热量支出时,最大可能超过上述平衡状态的温度;αQ/β表示仅仅由于反射辐射的热量支出,下垫面所要降低的温度;/β表示由于土壤热传导使下垫面降低的温度;/β相当于Penman蒸发公式的空气干燥力项,它反映近地空气层容纳水汽的能力,显然它控制着下垫面的蒸发速度,从而影响到下垫面的温度。
