摘要
Abstract
Base on the irrigation experiment of moisture and salt content migration of the vadose zones in-situ in the Zhangjiawan area, the paper analyzes the migration characteristics of moisture movement of unsaturated zones from the view of moisture energy. It shows that moisture migration of vadose zones can be roughly divided into three zones and the process of groundwater recharge under irrigation, the deep of the moisture migration. The ground water level rises very low under the condition of irrigation and the irrigation recharge quantity was very little, which was calculated by unsaturated lfow Darcy's law.关键词
