摘要
自2000年向塔里木河下游实施生态输水以来,国内大多数学者所关注的问题一直集中在如何确定下游生态安全保障体系的合理生态保护范围及生态需水量;如何通过河道水流演进—地下水位抬升—植被恢复等关联性问题的系统,为下游生态输水整体效益评估、河道整治、水资源合理配置与优化调度、生态重建提供科学依据等问题上。对于塔里木河下游生态应急输水工程影响后评价的研究现在还不多见。为此,本论文以塔里木河下游生态输水为背景,对该工程影响后评价的内容进行探讨,目的在于得出塔里木河下游生态应急输水工程影响后评价的研究框架,为客观,公正的评价该工程影响提供依据。
Ever since ecological water was fed to the downstream of the Tarim River, concerns have centered on how to define a rational ecological protection scope and ecological water demand for downstream ecological safety assurance system, and how to provide scientific basis through a system composed of such relative factors as river flow advance, rise of ground water level, and vegetation recovery for overall benefit assessment of downstream ecological-based emergent water conveyance project, river regulation, reasonable allocation and optimal scheduling of water resources, and ecological restoration. However, there have been just a few studies on impact-post assessment of ecological-based emergent water conveyance project at downstream the Tarim River. In view of this, this paper attempts to discuss the impact-post assessment of the said project with ecological-based water conveyance to the downstream of the Tarim River as the background, and aims to develop a study framework for that, offering a basis for an objective and fair assessment of the project＇s impacts.
