| 英文摘要 | Assessing rainfall interception (I-R) is a critical yet uncertain aspect in hydrological cycle, particularly the quantification of relative contributions from leaves and woody components (e.g., branches, stems, and trunks) to I-R. Nevertheless, the role of woody components in I-R estimation remains largely unexplored and thereby has been constantly overlooked. This study addressed this challenge and refined the widely-used Gash model to distinguish woody interception (I-W) from leaf interception (I-L). We incorporated the spatial variability of vegetation traits alongside satellite data in 2019 into the refined model, and spanned China's major forest types. The refined model showed a strong agreement with field observations in estimating I-R (r = 0.83, p < 0.01) and the fraction of rainfall interception to precipitation (I-R/P) (r = 0.77, p < 0.01). The average I-R was 112.4 +/- 32.1 mm (with I-R/P of 14.7 +/- 8.2%) in 2019, of which I-L accounted for 77.9% and I-W contributed the rest 22.1%. Among different forest types, I-W/I-R exhibited the highest values in deciduous needle-leaf forests (DNF, mean: 51.9%) but lowest values in evergreen broad-leaf (EBF, mean: 14.3%). In addition, I-W/I-R was larger in the non-growing season than that of growing season in some forest types, such as exceeding 60% in winter for DNF, indicating that more rainwater was intercepted by woody components than by leaves. Our study underscores the substantial role of woody components in I-R, particularly in needle-leaf forests, that are prevalent globally, a finding that can provide novel methods and valuable parameters for global hydrological models to improve the accuracy of model predictions. |
