| 摘 要： | 本文以四子王地区不同带间距柠条灌草复合模式为研究对象,对林地土壤水分的垂直和水平变化特征进行研究,结果表明:不同带间距林地土壤水分的垂直和水平变化特征均存在着很大差异。在水平方向上,16m带间距的土壤水分变化比较平缓;在垂直方向上,5m、10m带间距的大气降水补给并不能满足植物生长对水分的需求,需要消耗深层土壤水分满足植物的生长,而16m带间距由于大气降水的补给,土壤含水量能够满足植物生长的需要。

| Abstract: | The research object is shrub-grass compound model with different spacing in Siziwangqi,the soil moisture of shrub-grass compound model Caragana and grass,with different spacing in the vertical and horizontal distribution were analysised.The results were as follows:The mean different is significant among three model in the vertical and horizontal distribution.In the horizontal direction,Caragana and grass soil moisture of the 16m distance relatively stable distribution;In the vertical direction,because the d... |
