盐碱地盐碱地saline-alkali landyoniiandi盐碱地(saline一砒aliland)土壤表层积聚过多盐碱成分，对农作物有危害的土地。是盐地、碱地、盐化土地、碱化土地的统称。在土壤学中，把这类土地的土壤称为盐渍土或盐碱土。土壤中的盐碱成分，主要由钾、钠、钙、镁等阳离子与氯、硫酸根、碳酸根、重碳酸根等阴离子结合成多种盐组成，其中氯盐和硫酸盐类为中性盐，碳酸钠(苏打)和重碳酸钠(小苏打)为碱性盐。气候和水文地质条件是形成盐碱土的主要因素。降雨量少，蒸发量大，使土壤和地下水中残留比较多的盐分;地下水排泄不杨，水位高，潜水蒸发量大，溶解在地下水中的盐分，在蒸发作用下向表土层集积，因而产生盐碱化现象。在中国，内陆盐碱土主要分布在温带干早、半干早气候区;滨海盐土是因滨海土地受海水浸渍，土壤盐分以抓化钠为主;青藏高原的寒原盐土，主要分布在寒带、亚寒带干早、半干旱气候区的湖积物上。盐碱土对农作物根直接产生毒害，并提高土壤溶液的浓度，使作物吸收不到所需的水分，生长受到抑制，土壤有机质和养分含量低，土壤结构和物理性能不良，水、肥、气、热失调，是一种低产土壤。中国盐碱土地约有2仅进1.7万公顷，据1卯2年水利统计资料，中国盐碱耕地面积为763 .3万公顷，占耕地总面积8%。主要分布在黄淮海平原、东北的西部平原、黄河河套平原和西北内陆干早区。中华人民共和国建立以来，中国盐碱地改良取得长足进展。例如，黄淮海平原盐碱地采取“排、灌、平、肥、林、种、管”等综合措施治理，取得明显成效，农作物单产大幅度提高，并创造了曲周、陵县、封丘等试验区典型，可供借鉴。(梁佩谦)
