| 摘 要： | 以水盐动态变化为线索,综述了影响存量消减的因素和导致盐分增量的因素,旨在厘清土壤盐分变化的机理,分析各种影响因素之间的关系。结果发现,影响土壤盐分的因素主要有降水、排水、蒸发、地貌覆被、灌溉、施肥、大型工程等,且各种因素相互影响和制约。

| Abstract: | Mainly using the water salt dynamic change as the clue,this paper respectively summarized the influence factors of stock reduction and the factors causing salt increment,and aimed at the analysis of literature on influence factors of soil salinity,and in order to clarify the mechanism of the change of soil salinity,analyze the relationship between various factors.By the reorganization of literature,we found that the main influence factors of soil salt:precipitation,drainage,evaporation,landform cover,irrigation,fertilization,and large-scale projects,and each factor was not iso-lated to influence the distribution of soil salt but influenced and restricted it mutually. |
