| 摘 要： | 在黄土丘陵区有充分供水条件下的刺槐、白榆林内,分别应用自制小型蒸发计和常规的原状土柱田间法测量土壤蒸发量.经统计、分析,结果表明:小型蒸发计所测蒸发量与土壤实际蒸发量(田间法)有较好的线性相关性,其相关方程为E田=0.003 4+0.0332E小,相关系数0.9076.小型蒸发计具有轻便、观测简易、精确等优点,可以广泛应用于林地土壤蒸发研究中.

| Abstract: | At the saturation point,the soil evaporation of forest land in the gullied rolling loess region was measured using a light evaporograph and a conventional method (a direct gauge of the undisturbed soil column in the field).The observations in the stands of Siberian elm (Ulmus pumila) and black locust (Robinia pseudoacacia) with different densities suggest that there is a linear correlation for the observations obtained by the two methods.Correlation equations can be expressed as.Eσ=-0.003+0.033El,r=0.9076.In the equation,Eσdesignates the observation result mesured by the conventional method;El is mesured by using a light evaporograph.The light evaporograph is handy,convenient,accurate,and widely suitable for the study of soil evaporation of forest land. |
