中文摘要：

Populus euphratica Oliv 和 Tamarix ramosissima Ldb 的 eco 生理的反应和改编在水版本时期期间被调查。九个典型区域和 45 横断沿着 Tarim 河的更低的活动范围被选择。地下水桌子以及植物表演和脯氨酸，可溶的糖，和植物的内容内长的荷尔蒙(骆驼毛的织物， CTK ) 在叶子被监视并且分析。地下水桌子在不同区域被提起，横断走水路推出程序。生理的压力到 P。euphratica 和 T。ramosissima 在水版本以后被减少了。我们的结果建议在学习区域的地下水桌子在 3.15～4.12 m 留下了，从 9.28～11.06 的脯氨酸内容( mmol/L )，从 224.71～252.16 的可溶的糖内容( mmol/L )，从 3.59～5.01 的 ABA 内容( ng/g FW )，并且从 4.01～4.56 的 CK 内容( ng/g FW )，为最佳生长和 P 的恢复。植物性能参数和水申请的效率显示的 euphratica 最高。在学习区域的地下水桌子在 2.16～3.38 m 留下了，从 12.15～14.17 的脯氨酸内容( mmol/L )，从 154.71～183.16 的可溶的糖内容( mmol/L )，从 2.78～4.86 的 ABA 内容( ng/g FW )，并且从 3.78～4.22 的 CK 内容( ng/g FW )，为最佳生长和 T 的恢复。植物表演参数和水申请的效率显示的 ramosissima 最高。为在学习区域的植被的恢复的合理地下水桌子在 3.15 ～ 3.38 m。

英文摘要：

The eco-physiological response and adaptation of Populus euphratica Oliv and Tamarix ramosissima Ldb during water release period were investigated. Nine typical ＇areas and forty-five transects were selected along the lower reaches of Tarim River. The groundwater table as well as plant performance and the contents of proline, soluble sugars, and plant endogenous hormone （ABA, CTK） in leaves were monitored and analyzed. The groundwater table was raised in different areas and transects by water release program. The physiological stress to P. euphratica and T. ramosissima had been reduced after water release. Our results suggested that the groundwater table in the studied region remained at -3.15 to -4.12 m, theproline content from 9.28 to 11.06 （mmol/L）, the soluble sugar content from 224.71 to 252.16 （mmol/L）, the ABA content from 3.59 to 5.01 （ng/g FW）, and the CK content from 4.01 to 4.56 （ng/g FW）, for the optimum growth and restoration of P. euphratica indicated by the plant performance parameters and the efficiency of water application was the highest. The groundwater table in the studied region remained at -2.16 to -3.38 m, the proline content from 12.15 to 14.17 （mmol/L）, the soluble sugar content from 154.71 to 183.16 （mmol/ L）, the ABA content from 2.78 to 4.86 （ng/g FW）, and the CK content from 3.78 to 4.22 （ng/g FW）, for the optimum growth and restoration of T. ramosissima indicated by the plant performance parameters and the efficiency of water application was the highest. The rational groundwater table for the restoration of vegetation in the studied region was at -3.15 to -3.38 m.
