Understanding rainfall partitioning by shrub canopies is essential for assessing water balance and improving hydrological models in cold regions. From 2010 to 2012, field experiments were conducted the Hulu catchment of Qilian Mountains, focusing on Potentilla fruticosa Caragana jubata during growing season. Throughfall, stemflow, interception loss measured using rain gauges, stemflow collars, a approach. A total 197 natural events recorded, precipitation characteristics analyzed relation intensity, amount, vegetation traits. One-way ANOVA regression analyses used test differences correlations. The results showed that critical threshold generating throughfall was 1.9 mm. For P. fruticosa, throughfall, accounted 66.96%, 3.51%, 29.53% gross rainfall, respectively; corresponding values C. 67.31%, 7.27%, 25.42%. Significant (p < 0.05) observed between species. Partitioning components positively correlated with amount stabilized at ~4 mm h−1 intensity. Interception percentage decreased intensity plateaued 2 5 jubata. These findings provide empirical evidence modeling canopy redistribution alpine environments.
