| 摘 要： | 以塔里木河下游为研究区域,分析了生态输水工程实施以来该区地下水埋深、水质、植被生长状况的不同响应程度。研究表明:生态输水工程使得原本较低的地下水位在一段时间内得到抬升,局部生态环境得到改善,尤其在输水中期(2003-2005年),植被物种组成发生变化,物种多样性增加,植被盖度提高,地下水水质有所好转;但2007年以后,尤其是2008年,随着输水的间断,下游地下水位开始回落,草本植物物种数量又开始减少,因此,生态输水工程必须持续进行才能真正挽救塔里木河下游生态环境。

| Abstract: | Taking the lower reaches of Tarim river as research area,the response degrees of groundwater table,water quality and plant growth situation are analyzed after the project of ecology water transportation are put in practice.The results indicate that the ground water table imbedded lower lever was increased during certain period of time and the eco-environment has been improved in the partial area by implementing the engineering.Especially in the middle transportation period from 2003 to 2005,the vegetation s... |
