通过回顾盐碱地治理研究的发展历史,分析传统盐碱地治理方法存在的不足,提出了"改排为蓄、水地共处、和谐生态"的新模式.新模式提出循环压盐理论,认为通过蓄水沟系蓄水可实现水地动态分布,进而改变土壤中盐分的分布,同时根据蓄水沟蓄水高低及水中盐碱浓度多少,依靠小范围内的微循环加速水盐交换,压盐改良耕地;通过实验观察得出在蓄水条件下土壤饱和层和非饱和层之间存在一个10～20 cm的过渡层,过渡层对下层高含盐有隔离作用.分析长期田间试验观测资料,得出在改排为蓄的治理模式下,土壤质量逐年提高.

The history of saline land improvement was reviewed and the deficiency of traditional treatment methods was analyzed. Based on which, the comprehensive new treatment model of "change drainage to impoundment, water and land get along, harmonious ecological" was proposed. Restraining salt content cycle was proposed. Ditch system of water storage can change salt distribution; microcirculation in small scale can accelerated water and salt exchange. According to the experiment, the results showed that stability of groundwater level, there will be a transition layer(10～20 cm),the transition layer have a remarkable isolation effect on salt of lower layer. From the data of the long-term observation during 10 years in Lubotan, Shaanxi, the land quality is improving in a favorable direction.
