土壤盐渍化（soil salinization）是指土壤底层或地下水的盐分随毛管水上升到[[地表]]，水分蒸发后，使盐分积累在表层土壤中的过程。是指易溶性盐分在土壤表层积累的现象或过程，也称'''盐碱化'''。中国盐渍土或称盐碱土的分布范围广、面积大、类型多，总面积约1亿公顷。主要发生在干旱、半干旱和半湿润地区。盐碱土的可溶性盐主要包括钠、钾、钙、镁等的[[硫酸盐]]、氯化物、碳酸盐和重碳酸盐。硫酸盐和氯化物一般为中性盐，[[碳酸盐]]和重碳酸盐为碱性盐。<ref>[https://wenda.so.com/q/1616513142215405 盐碱化的概念及产生原因],360问答 , 2020年1月16日</ref>
