中文摘要	在干旱区,水是植物生长发育的主要限制性因子。运用稳定氧同位素技术探究了准东地区生长在相邻地段不同径级的梭梭(Haloxylon ammodendron)和白梭梭(Haloxylon persicum)的水分来源。通过测定不同径级梭梭和白梭梭的小枝木质部水、不同土层的土壤水以及地下水的delta~(18)O同位素值,运用MixSIAR模型、平均吸水深度模型和直观图法分析不同径级梭梭和白梭梭对各潜在水源的利用比例和主要吸水层位。结果表明:生长在丘间低地的四个径级梭梭主要水源是土壤水,随着径级的增长,梭梭水分利用方式更加灵活,趋向于利用稍浅层的土壤水。生长在沙丘顶部的四个径级白梭梭主要水源是土壤水,随着径级的增长,白梭梭更趋向于利用深层土壤水。梭梭和白梭梭通过不同的水分利用策略合理的利用干旱区有限的水源。
英文摘要	Water is the principal limited factor for plant growth in arid area. In this paper,Haloxylon ammodendron grows at inter-dune lowland and Haloxylon persicum grows at the sand dune were chosen,and stable oxygen isotopes technology was used to study the water sources of the two species of different diameter classes in the eastern Junggar Basin. The oxygen isotope ratios(delta~(18)O) of xylem water of H.ammodendron and H.persicum of different diameter classes,soil water in different soil layers,and groundwater were measured. The MixSIAR model was used to calculate the possible ranges of potential water sources used by H.ammodendron and H.persicum,while graphical inference method and mean depth of water uptake model were used to determine the main soil layer absorbed by the two species. The results showed that soil water was the main water source for H.ammodendron of four different diameter classes. The Ⅰ(d≤1 cm) diameter class of H.ammodendron mainly used shallow soil water(060 cm), with the possible contribution proportion of (45.4 10.9) %,and its water uptake soil depth was at 4060 cm. The Ⅱ (1 cm< d≤5 cm) and Ⅲ (5 cm< d≤10 cm) diameter classes of H. ammodendron mainly used deep soil water(140200 cm), with the possible contribution proportion of (40.711.5) % and (41.711.8) %,respectively,and their water uptake soil depth were all at 140160 cm. The Ⅳ (10 cm
