英文摘要	Information for the interspecific variation in plant stemflow production may provide important implications for their survival in drought conditions. Our objectives were to determine if stemflow generation varied with plant species and to ascertain their possible responses to rainfall characteristics and plant morphology. Stemflow volume (SFv), stemflow depth (SFD), stemflow percentages of gross rainfall (SFD/GR), and funnelling ratio (FR, a quantitative index to evaluate water enrichment by stemflow) were quantified in 2014 and 2015 for coexisting two tree species (Pines tabulifomis and Armeniaca vulgaris) and two shrub species (Salix psammophila and Caragana korshinskii) on the Loess Plateau of China. The results indicated that the generation of stemflow varied significantly among the studied four species. The shrub species had larger values of SFv, SFD , and SFD/GR than tree species. FR values revealed that the soil at the plant bases for P. tabuliformis, A. vulgaris, S. psarrunophila, and C. korshinskii, could receive averages of 13.1-, 23.9-, 78.2-, and 124.9-fold more rainwater, respectively, than an equivalent open area. Characteristics of rainfall had a notable influence on stemflow production. Specifically, SFN, and SFD were all positively and linearly correlated with rainfall in 2014 and 2015. SFD/GR and FR increased linearly with rainfall in 2014, whereas increased exponentially or even decreased after reaching a rainfall threshold in 2015. Significant influence of plant morphology on stemflow production was only observed for P. tabuliformis but not for the other species. In conclusion, the studied two shrub species (S. psammophila and C. korshinskii) were morphologically more effective than the tree species (P. tabuliformis and A. vulgaris) in funnelling rainwater to the soil of the basal area. This could be eco-hydrologically significant for their survival in drought environments.
