| 英文摘要 | Rivers losing flow into surrounding aquifers ('losing' rivers) are common under changing climates and groundwater overexploitation. The riparian plant-water relations under various water table dynamics along a losing river remain unclear. In this study, the water isotopes (delta H-2 and delta O-18), leaf delta C-13, and MixSIAR model were used combinedly for determining the root water uptake patterns and leaf water use efficiency (WUE) of Salix babylonica (L.) at three sites (A, B, and C) with different water table depths (WTDs) in the riparian zone of Jian and Chaobai River in Beijing, China. The correlations of water source contributions with WTD and WUE were quantified. The riparian S. babylonica primarily took up upper (0-80 cm) soil water (71.5%) with the lowest leaf delta C-13 (-28.8 +/- 1.1 %o) at site A under deep WTD (20.5 +/- 0.5 m). In contrast, deep water below 80 cm depth including groundwater contributed 55.1% to S. babylonica at site B with fluctuated shallow WTD (1.9 & PLUSMN; 0.4 m), where leaf 813C was highest (-27.9 +/- 1.0 %o). The S. babylonica mainly used soil water in 30-170 cm layer (56.9%) with mean leaf 813C of -28.2 %o +/- 0.7 %o at site C with stable shallow WTD (1.5 +/- 0.1 m). It was found that both the contributions of upper soil water in 0-80 cm and deep water below 80 cm had significantly quadratic correlations with WTD under shallow water table conditions (p < 0.05). Leaf delta C-13 was negatively correlated with contributions of upper soil water above 80 cm depth, but it was positively related to the con-tributions of deep water below 80 cm in linear functions (p < 0.001). The results indicated that 2.1 m was the optimum WTD for riparian trees, because they maximized the use of deep water sources to get the highest WUE. This study provides insights into managing groundwater, surface water resources and riparian afforestation in losing rivers. |
