Rainfall partitioning, a crucial process in shaping the local hydrological cycle, governs canopy interception and subsequent soil water recharge. While structure meteorological conditions fundamentally regulate this process, role of plant self-organization its interactions with drivers (non-precipitation variables particular) remain underexplored. To address gap, we investigated rainfall partitioning components, including amount, intensity, efficiency, temporal dynamics throughfall stemflow, clumped scattered Vitex negundo L. var. heterophylla (Franch.) Rehder shrubs Yangjuangou catchment Chinese Loess Plateau during 2021–2022 rainy seasons. Despite comparable net precipitation (clumped: 83.5% vs. scattered: 84.2% incident rains), divergent strategies emerged. Clumped V. exhibited greater stemflow (8.6% 5.2%), characterized by enhanced favorable dynamics. Conversely, favored generation (79.0% 74.9%). Consistent previous research, amount was recognized as primary control on rains. Furthermore, our integrated analysis, combining machine learning variance decomposition, highlighted critical roles antecedent wetness (4 h pre-event leaf wetness) wind speed thresholds (e.g., low gust) regulating efficiency These findings advance mechanistic understanding interplay between processes, demonstrating how morphological adaptations optimize harvesting semi-arid ecosystems. This addressed need to incorporate dynamic interplays (specifically, self-organized patterns) factors (particularly non-precipitation variables) into ecohydrological models, especially for improved predictions water-limited regions.
