| 摘 要： | 通过对自然状态下典型的天津滨海盐渍土进行定期调查和监测,研究天津滨海盐渍土的水盐运动规律。结果表明:土壤剖面中盐分含量随季节性变化存在明显的积盐、脱盐过程。土壤的盐化程度越高,盐分的积累与淋溶变化幅度就越大,土壤表层盐分变化频繁,变化幅度较大,底层盐分变化幅度较小。

| Abstract: | Based on the regular investigating and monitoring of typical coastal saline soil under natural conditions in Tianjin, the watersalt movement of coastal saline soil was studied. The results indicated that the salt content of soil profile had obvious salification and desalination process with the seasonal changes.The higher of soil salinization degree was, the larger rangeability of salinization accumulate and leaching.The salinization of surface soil changed frequently and greatly, while the salinization of bottom soil changed in a smaller extent. |
