A study on the evolutionary characteristics and correlations between multi-scale precipitation and soil moisture at different depths in ecological sub-basins of the Loess Plateau
The Wangdonggou ecological small watershed was taken as the research object. Based on the hourly monitoring data from 2020 to 2025, the multi-time-scale analysis framework of ‘hour-day-month-aggregation period’ was constructed, and the time-lag cross-correlation was adopted. The vertical lag response law of soil mois...
