地下水与土壤盐渍化关系的动态模拟

在大气－土壤－地下水连续系统中，本文将土壤水－地下水部分动力学理论和数值模拟技术结合的方法，研究了地下水与土壤盐渍化关系，并进行了动态模拟。在完成土壤水盐数据自动采集系统研制、水盐运动参数测定，数学模型建模识别，数值计算方法选择评价４项基础研究后，针对干旱区的一个大型灌区土壤－水环境中溶质迁移动态进行了系统模拟，获得复杂环境条件下多因子、多处理组合模式化的图谱，有助地下水与土壤盐渍化定量关系深入揭

Dynamic simulation of the relationship between water table and salinization of soil

The relationship between water table depth and saliniztion of soil has been studied by numerical simulation on the basis of theory of the soil water dynamic and solute transport in the Atmosphere Salinization of Soil Ground water Continuum(ASGC).Four fundamental research on systematic simulation and relevant software have been completed:1,computer management system to make automatic data collection of soil water and salt concentration.2,determination experiments of soil water and salt movement parameters in saturated and unsaturated soil.3,calculation model establishment of solute transport.4,numerical method which can solve complex mathematical problems based on the solute transport model.based on the dynamic siumlation of solute transport in the soil water environment of a large arid irrigation area,114 multi factor and multi case charts in the complex environment have been completed.This is helpful for revealing quantitative correlation and mechanism of water tablel and salinization of soil as well as the management and calculation of soil water resource.
