| 图5 5月22日6.7 mm和8月31日7 mm降水脉冲下土壤水δ18O值(A, B)和梭梭木质部水δ18O值(C, D)的变化(平均值±标准误差, n = 4)。五角星所在位置为降水发生的日期以及对应的δ18O值。灰色横条代表当月地下水的δ18O值(平均值±标准误差, n = 4)。 |
| Fig. 5 Responses of δ18O values of soil water (A, B) and δ18O values of xylem water in Haloxylon ammodendron (C, D) to 6.7 mm precipitation on May 22 and 7 mm precipitation on August 31 (mean ± SE, n = 4). Stars indicate the day of precipitation and δ18O values of precipitation, and gray horizontal bands represent δ18O values of groundwater in May and August, respectively (mean ± SE, n = 4). |
