一、问题的提出众所周知,蒸发因素在盐渍土的发生与演变过程中,起着极为重要的外因作用;蒸发因素与盐渍土的形成有着密切的关系.在研究盐渍土的文献中,也往往将蒸发因素与土壤和地下水条件相提并论.但是,目前在陆面或水面的水分蒸发量的测量和理论计算方面,由于种种原因,尚未得到圆满解决.作者观察到,在一部分盐渍土研究文献中,在有关蒸发的问题中亦因之而出现了一些问题.为了研究和 First, the issue is raised As we all know, evaporation in the occurrence and evolution of saline soil plays an extremely important role in external factors; evaporation factors and the formation of saline soil is closely related.In the study of saline soil literature, However, the current evapotranspiration measurements and theoretical calculations on the land or water surface have not been satisfactorily solved for various reasons. The authors observed that in some areas of saline soil research In the literature, some problems have also arisen in the issue of evaporation. In order to study and
