中文摘要：

在对塔里木河下游生态环境本底状况调查的基础上，通过大量的监测资料，应用河道水力学、地下水动力学、植被生态学以及系统分析与优化方法，对五次应急输水植被生态响应效应，进行了全面系统地评价。科学地确定了合理的生态修复目标和下游河道输水与区间水量优化配置方案。为创建和完善干旱区受损生态系统输水、修复与重建的评价体系奠定了理论和实践基础，也为塔里木河流域综合治理提供了重要的技术支撑。

英文摘要：

In this paper, on the basis of local survey of the lower reaches of Tarim River eco - environment and a large number of monitoring data, by application of river-hydraulics, groundwater mechanics,vegetation ecology as well as system analysis and optimization methods, we made a comprehensive systematic evaluation on the 5 e- mergency water supply response and the effect of water vegetation ecology, and determined scientifically the sound of ecological restoration goal and downstream river water quality and interval optimization probqam, we laid a theoretical and practical basis for establishment of evaluation system for assessing the creation and improvement of damaged eco - systems in arid zone and also provided important technical support for the comprehensive gov- ernance of the Tarim watersed.
