项目摘要
Salt accumulation in irrigated arid lands constitutes a serious problem. For estimation of the dynamic solute transport using numerical simulation, evaluation and standardization of in situ measurement of soil hydraulic and solute transport properties are required. In this study, various in-situ practical measurements of field saturated hydraulic conductivity and unsaturated hydraulic conductivity were carried out using a constant head infiltrometer, a pressure infiltrometer, a tension disk permeameter, and a cone permeameter. Internal drainage method using profile probe, inverse analysis of hydraulic properties using genetic algorithms, transient evaporation method for the low water content range, modified multi-step outflow method and inverse method of multi-layer were developed for the estimation of hydraulic properties. Hydrodynamic dispersion in soils was estimated with four-electrode salinity probes. Simultaneous measurement of water flow, solute and heat transport properties by multi-functional heat pulse probe and TDR sensor with thermocouple was carried out to eliminate spatial variability in situ. A Web-Based-Common-Interface (WBCI) to enhance collaboration between data bases of Soil Information System (SIS) was developed. The WBCI may help in developing soil water and solute transport characteristics data base as well as solute transport characteristics data base and in situ measurement methods for analyzing transport phenomena in soils.
灌溉干旱土地的盐分积累是一个严重的问题。为了利用数值模拟来估计动态溶质运移,需要对土壤水力学和溶质运移特性的原位测量进行评估和标准化。在这项研究中,各种现场实际测量的领域饱和导水率和非饱和导水率进行了使用恒水头入渗仪,压力入渗仪,张力盘渗透仪,和锥形渗透仪。提出了剖面探针内排水法、遗传算法水力特性反分析法、低含水量区瞬时蒸发法、修正多步出流法和多层反分析法等水力特性计算方法。土壤中的水动力学弥散估计与四电极盐度探头。采用多功能热脉冲探头和带热电偶的时域反射传感器同时测量水流、溶质和热输运特性,以消除空间变异性。为了加强土壤信息系统(SIS)数据库之间的协作,开发了一个基于Web的公共接口(WBCI)。WBCI有助于建立土壤水分和溶质运移特征数据库、溶质运移特征数据库和分析土壤中溶质运移现象的原位测量方法。
