Abstract The forest canopy affects the water entering ecosystem by intercepting rainfall. This is especially pertinent in forests that depend on rainfall for their ecological needs, quantifying and simulating interception losses provide critical insights into hydrological processes. In semi‐arid areas of Loess Plateau, afforestation has become an effective restoration measure. However, process these plantations still unclear. To quantify model plantations, we conducted a two‐year redistribution measurement experiment three typical including deciduous broadleaf plantation ( Robinia pseudoacacia ) two evergreen coniferous Platycladus orientalis Pinus tabuliformis ). Based this, revised Gash was used to simulate losses, applicability across varying types further compared verified. clarified proportions throughfall gross , were 84.8%, 70.4%, 75.6%; corresponding, stemflow 2.0%, 2.2%, 1.8%; 13.2%, 27.4%, 22.6%, respectively. dominant pattern during characterized low‐amounts, moderate‐intensity, short‐duration, which highest observed.

Rainfall Partitioning Dynamics in Xerophytic Shrubs: Interplays Between Self-Organization and Meteorological Drivers

Forests, Journal Year: 2025, Volume and Issue: 16(4), P. 605 - 605

Published: March 30, 2025

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.

Rainfall Partitioning by Two Alpine Shrubs in the Qilian Mountains, Northwest China: Implications for Hydrological Modeling in Cold Regions

Forests, Journal Year: 2025, Volume and Issue: 16(4), P. 658 - 658

Published: April 10, 2025

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.
