| 摘 要： | 由于近50a来人类不合理地资源开发,造成塔里木河下游的生态环境问题日趋严峻.为拯救下游绿色走廊,恢复和重建受损的下游生态系统,于2000年7月始,实施了塔里木河下游应急生态输水工程,水流于2001-11-02流进塔里木河尾闾--台特玛湖,使干涸近30a的台特玛湖重新受到水的滋润.笔者根据近2a在塔里木河下游的监测结果,通过对塔里木河下游地下水在河道纵向、横向的响应,地下水位响应强度及地下水位的变化带来下游天然植被的变化等方面对塔里木河下游生态输水工程进行阐述,分析了生态输水后地下水位响应的初步规律.研究结果表明:地下水位在一定范围内对生态输水的响应很明显,并由此带来下游生态环境向有利的方向转变.

| Abstract: | Due to unreasonable human exploitation of natural resources in recent 50 years,many environmental problems have appeared at the lower reaches of the Tarim River.In order to restore the "Green Corridor" and the environment in the downstream,the emergency ecological water transport project in the lower reaches of the Tarim River was carried out from June 12,2000.The water flowed into Taitema Lake,tail section of the Tarim River,on November 2,2001.Taitema Lake,which has been extinct for nearly 30 years,was restored with water.According to monitoring data in the lower reaches of the Tarim River in about 2 years,the response range and extent of the groundwater were described;the response intensity of groundwater level and the variation of natural vegetation in the lower reaches as a result of change of the groundwater level were also described;and the rules of groundwater response to the ecological water transport were thus analyzed preliminarily.It was shown that the response of groundwater level to the ecological water transport is very obvious to certain extent,which should bring about favorable changes of the eco\|environment in the lower reaches. |
