摘要:

研究内陆盐碱土水盐运移规律,开发水盐调控决策系统,为内陆盐碱土壤水盐合理调控提供理论依据和实用软件。通过对浅层地下水埋深、地下水和土壤水分盐分含量、离子组成等进行多年多点监测和分析,系统研究了盐碱地水盐运移规律,构建了内陆盐碱土水盐调控技术体系,形成了相应的决策系统。结果表明:内陆盐碱土水盐运动主要表现为:积盐、脱盐和相对稳定3种形式的运移和转换,水盐调控的关键是控制和降低积盐高峰期的土壤含盐量。在新疆内陆盐碱区应用后表明,本研究的水盐调控方案有效实现了时空避盐,降低了改良成本,减少了对环境的干扰。本研究采用信息技术开展了内陆盐碱地水盐规律的探索和应用,促进了水盐调控水平的提升。

Abstract:

The objective is to study water-salt transport law in the inland saline-alkaline soil, develop a water-salt control decision-making system, and provide a theoretical basis and practical software for the reasonable water-salt control in inland saline-alkaline. The shallow groundwater depth, the salt content of groundwater, soil moisture, soil salinity, and ion composition of multi-year and multi-site were monitored and analyzed. The law of water-salt movement in saline-alkali land was studied, the technical system of water-salt regulation was constructed systematically, and related decision-making system was developed. The results showed that the main performance of water-salt movement in the inland saline-alkali soil was transporting and transforming of three forms: salt accumulation, salt desalination and relatively stable. The key of water-salt regulation was controlling and reducing the salt content in soil at salt accumulation peak. This water-salt control scheme was feasible and effective on space-time salt avoidance, and could reduce the cost of soil improvement and the interference to environment. The study, by information technology, explored the law of water-salt in inland saline-alkaline soil and put it into application, and promoted the water-salt regulation.

Key words: water-salt regulation, inland alkali soil, decision system, water-salt monitoring, water-salt transport, Xinjiang saline-alkali area
