摘要
利用贵州省12个土壤水分观测站的小时土壤水分及降雨数据,对持续干旱、连续阴雨天气背景下土壤水分的垂直变化特征进行研究。分析了一次降雨过程中不同深度土壤水分时空变化特征,并根据仁怀、镇远、罗甸、荔波土壤剖面各层次土壤水分变化图,对降雨过程中土壤水分的垂直变化规律进行了探讨。
Hourly soil moisture and rainfall data which from 12 soil water observation stations were used to analyse vertical variability of soil moisture under continuous drought or rainy conditions. The space-time characteristics of different depths soil moisture in one-time rainfall process was analysed, and the vertical changing regularities of soil moisture was discussed based on soil profile moisture variation diagram of Renhuai, Zhenyuan, Luodian and Libo.
