土壤冻结过程中水分迁移动向的研究
A STUDY ON WATER MOVEMENT TREND DURING SOIL FREEZING
摘要
Abstract
In the areas of seasonal and perennial frozen soil, soil layers always contain different exent free stagnant water and frozen stagnant wa ter, which may save the pressing need of water for spring plants. The paper, acc ording to the laboratory stimulation of water movement in soils during freezing, analyzed formation and affecting factors for frozen stagnant water. In light of the fact that water content obviously increased after freeze. The authors advan ced technical measures for afforestation in arid regions, aiming to using this p art of water to assure plant's survival and growth.关键词
