| 摘 要： | 通过定点监测并结合统计方法分析了干湿交替时节一次降雨过程前后不同土地利用方式下土壤水分与土壤温度的动态变化特征.结果表明,降雨过程对土壤水分和土壤温度在时间动态变化和深度变化过程有着重要影响;降雨影响周期中土壤含水率在一定深度范围内有一次明显的升高过程,从降雨前到降雨后呈现低→高→低的变化趋势,其变异程度随着深度的增加...

| Abstract: | To understand the effect of rainfall on soil water and soil temperature in arid loess region.This research gave an analysis of the dynamic changes of soil water and soil temperatures under different land use system during once rainfall at the time of alternation of drying and wetting.The results showed that: there is a great effect of the process of rainfall on the time and depth dynamic changes of soil water and soil temperature.During a certain depth soil water had a sharp increment within the effect peri... |
