| 摘 要： | 本文对隰县试区河沟流域山水沟水平阶整地的新造林地，设置固定观测样点，分别不同坡度、坡向和坡位对０～５０ｃｍ土层水分状况进行了测定，分析了晋西南残塬沟壑区半干旱区不同条件下的水分差异及其动态，找出了造林关键时期浅层土壤水分变化规律。在此基础上为提高造林成活率，在造林技术上采取了相应的对策。

| Abstract: | In the new sites of afforestation with narrow terrace at Shanshuigou gully of Hegou watershed in Xixian,fixed sample spots were designed.and the water status within 0￣0cm soil layer in differentslops,aspect of slpoe,and position of slope was measured respectively.The difference of water and its dynamic under different conditions in semiarid zones of broken loess plateau gully region in southwesten Shanxi were analysized.The changing laws of the water of shallow soil layer in afforestation period have been found. Based on these,for the purpose of improving survival rate of afforestation.the corresponding strategic measures have been taken in affoestation techniques. |
