寒区闭流区土壤水分垂向渗流系统物理模拟试验装置分析与设计

Analysis and Design on the Physical Simulation Experiment Device of Vertical Infiltration System of Soil Water in Frigid Zone and Closed Drainage Area

土壤入渗是大气降水、地表水、地下水和土壤水相互转化的一个重要环节,入渗试验是研究土壤入渗的重要手段。以乌裕尔河、双阳河闭流区为研究对象,以入渗试验为基础,基于不同的气候条件和试验原理,分别对积水条件下的土壤水分垂向变化试验装置、蒸发条件下的土壤水分垂向变化试验装置和冻融条件下的土壤水分垂向变化试验装置进行了分析与设计,以便找到研究寒区闭流区土壤水分运移的最佳试验方法。

Soil infiltration is a major section of the transformation among precipitation, surface water, underground water and soil water; infiltration experiment is an important means to study it. The paper based on infiltration experiment, taking the frigid zone and closed drainage area between Wuyuer River and Shuangyang River as an example, analyzes and devises the physical stimulation experiment equipment to study vertical infiltration system of soil water in these areas.
