摘要

土壤蒸发受许多因子的影响

主要是土壤含水量与枯枝落叶厚度。有5cm厚油松枯枝落叶覆盖下的土壤蒸发的数学模型是Qt=[652.5e

0.0166t

通过检验发现它能够描述土壤蒸发的规律

且参数易于确定

利用方便。

Abstract

Soil water evaporation is affected by many factors

but the main factors are soilwater and litter thickness. A mathematical model on soil water evaporation under littercover of 5 cm in thickness is: Q_t = (652.5e~(0.0166)t -660.5)/e~(0.0166)t. It has been foundthrough testings that this mathematical model can be used to describe the rule of soilwater evaporation

and its parameters are easy to be fixed and convenient to be used
