| 英文摘要 | Stemflow is an important water flux in forested ecosystems, which is influenced by both biotic and abiotic factors. The stemflow funneling ratio, F-P, is a straightforward parameter to express the funneling efficiency of individual trees,F-P,F-Bt, or at the stand-scale, F-P,F-Bs. Nevertheless, no known studies have compared the F-P and its influencing factors between tree- and stand-scales in a subtropical deciduous forest. In this study, F-P values from Q. acutissima and B. papyrifera trees were computed for a subtropical area of eastern China, and examined in relation to five biotic variables and ten abiotic variables. The relative contribution ratio (R-CR) of each biotic and abiotic variable to F-P,F-Bt and F-P,F-Bs were evaluated by relative importance analysis. The median F-P,F-Bs of B. papyrifera (104.2) was significantly higher than that of Q. acutissima (62.2), with the median F-P,F-Bt of Q. acutissima and B. papyrifera both varying greatly among individual trees. Projected crown area (R-CR = 29.2%) and diameter at breast height (R-CR = 21.4%) were the two most important biotic factors governing F-P,F- Bt of Q. acutissima, while the two critical biotic factors affecting F-P,F-Bt of B. papyrifera were trunk lean (R-CR = 62.2%) and tree height (R-CR = 15.1%), respectively. At the stand scale, gross precipitation (G(P)), rainfall duration (D-E) and vapor pressure deficit (D) were the three most critical factors affecting F-P,F-Bs of Q. acutissima and B. papyrifera. G(P) and D-E exerted positive effects but D a negative effect on stemflow generation. These findings provide new insights into the FP at both tree- and stand-scales within subtropical ecosystems. |
