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.
In the Loess Plateau under the condition of adequate water supply, soil evaporation was measured by self-made small-scale evaporation meter and conventional soil-column method, respectively.The results of statistics and analysis showed that the evaporation measured by the small-scale evaporation meter And soil actual evaporation (field method) has a good linear correlation, the correlation equation is E = 0.003 4 +0.0332E small, the correlation coefficient of 0.9076. Small evaporation meter with light, simple observation, accurate, etc., can be widely Applied to forest soil evaporation research.
