内蒙古河套灌区冻融土壤水分迁移简化模型
Simplified Model Simulating Soil Moisture Migration during Freeze and Thaw in Hetao Irrigation District, Inner Mongolia
摘要
Abstract
The measured data, which were gathered from 14 freeze-thaw cycles in 1990--1999 and 2002-- 2007 in Hetao irrigation district, were analyzed in this paper. The method of water balance analysis was adopted to estimate the amount of soil moisture migration in these cycles. This paper proposed a method to estimate the quantity of migration water according to groundwater tables through the entire freeze-thaw cycle. Meanwhile, some empirical equations were proposed to calculate the freezing depth, and groundwater drawdown and rise in freeze-thaw cycle.关键词
