灌水(降雨)对各层土壤基质势的影响随深度的增加而减小。
The influence caused irrigation (rainfall) is to each layer soil matric potential reduces with depth of increment.
通过相关性分析得出土壤基质势，叶水势，大气水势三者在时间和空间上都有很大的差别。
Soil matric potential, leaf water potential and atmosphere water potential is diversity in temporal and spatial variation.
其原因是土壤水运动是在相应的基质势梯度作用下发生的，而并不需要对应的含水量梯度。
The reason is that it is under the effect of matrix potential gradient in stead of moisture content gradient.
