中文摘要	【目的】在克拉玛依造林碳汇基地外围,对比分析梭梭和柽柳蒸腾耗水的差异性。【方法】使用包裹式茎流计(Flow4)对梭梭(Haloxylon persicum)和柽柳(Tamarix elongata)枝液流动态进行了监测。对液流速率和枝直径进行相关性分析和回归分析。【结果】梭梭和柽柳枝液流速率同枝直径达到显著相关,可分别使用幂函数和指数函数进行拟合。在1.0-3.0 cm的枝直径范围内,柽柳的液流速率大于梭梭,液流速率均随枝直径的增大呈减小,液流速率的差异在减小。【结论】在1.0～3.0 cm的径级范围内梭梭抗旱能力强于柽柳,随着植株的生长梭梭和柽柳抗旱能力增强,柽柳抗旱能力同梭梭的差距逐渐变小。
英文摘要	[Objective] The purpose of this program is make a contrastive analysis of the transpiration water consumption between Haloxylon persicum and Tamarix elongate in Arid Regions.[Method] Flow4 was used to measure the sap-flow dynamics in outer margin of Karamay Cabe forest during 10-30 of July,2010.The correlation and regression between sap flow velocity and diameter of branch were analyzed.[Result]We found that there was a significant correlation between sap flow velocity and diameter of the branch.The relation can expressed as power function and logarithmic function.The sap flow velocity of Tamarix elongate was greater than Haloxylon persicum’s and the sap flow velocity and difference between them bacame smaller with the increase of branch’ s diameter.[Conclusion] Haloxylon persicum’ s drought resistance was stronger than Tamarix elongate when diameter of branch ranging from 1.0 to 3.0 cm.The drought resistance became stronger with the development of the plant and reducing the differences between Haloxylon persicum and Tamarix elongate.
