盐碱土盐化或碱化形成的一系列土壤。又称盐渍土，包括盐土、碱土及各种盐化和碱化土壤。狭义的盐碱土是指既盐化又碱化的土壤。中国主要分布在华北、东北和西北的内陆干旱、半干旱地区，东部沿海包括台湾省、海南省等岛屿沿岸的滨海地区也有分布。盐土是在气候干旱、蒸发强烈、地势低洼、含盐地下潜水位高的条件下，使土壤表层或土体中积聚过多的可溶性盐类而形成的。盐土一般呈碱性反应（部分滨海酸性硫酸盐盐土有酸化现象），盐基呈饱和状态，腐殖质含量低，典型盐土剖面地表有白或灰白色盐结皮、盐霜或盐结壳。划分盐土的表层含盐量下限指标，因盐分组成而异，以氯化物为主的下限指标为0.6％左右,氯化物和硫酸盐混合类型的盐土下限指标为1％左右,含石膏较多的硫酸盐土下限指标为2％左右。当100克土壤的可溶盐组成中含苏打在0.5毫克当量以上，pH多大于9，含盐量大于0.5％时，属苏打盐土。当土壤碱化层交换性钠占交换性阳离子总量（碱化度）20％以上，土壤呈强碱性，pH大于9,表层含盐量不及0.5％时，称为碱土。低于上列含盐下限指标,而其含盐量大于0.1％，或碱化度大于5％者，则按对植物的危害程度，将其划分为轻度、中度、重（强）度盐化或碱化土。盐土中含有过多可溶性盐类，增高土壤溶液的渗透压，引起植物生理干旱；某些盐类离子，直接毒害植物根系，造成植物吸收营养元素的比例失调；碱土中土壤胶体含有大量交换性钠，增加土壤碱度和恶化土壤物理化学性质，土壤湿时膨胀泥泞、干时收缩坚硬，通透性、可耕性极差。盐碱土改良应因地制宜地采取各种井、沟、渠相结合的灌排水利措施，同时结合各种农业生物措施、进行综合治理，以排除过多盐碱和提高土壤肥力。
