塔里木河下游生态输水及河道生态整治工程探讨

通过近几年向塔里木河下游的应急生态输水，水流到达塔里木河尾间台特玛湖，沿岸地下水位上升，沿河部分地段植被长势得以恢复，局部地区生态环境改善。为了从根本上解决塔里木河下游的生态环境问题．探讨了下游河道生态整治工程，包括河道疏浚输水线路选择和设置生态闸的问题。大西海子水库下游河道疏浚工程有3条输水线路可供选择，通过投资、占地、施工、管理、防洪等综合比较，选择在大西海子水库主坝上新建一座放水闸方案。方案在技术上和经济上是可行的。本着尽量少而又要满足河道疏浚后沿岸植被生长需水的原则，分析了沿岸生态闸设置的必要性和保护的生态植被的面积，并探讨了今后生态输水方式的选择与生态闸的开启顺序。

Ecological Water Transport and River Improvement at Lower Reaches of Tarim River

After the project of transferring ecological water at the lower reaches of Tarim river in recently years, water flow into Taitema lake, groundwater level along Tarim river rose. Correspondingly, the vegetation health improved in this region. For the purpose of improving environment for a long time at the lower reaches of Tarim river, discuss river improvement, include river dredging and ecological sluices. For the purpose of solving downstream water interception and ecological environment problems in Tarim river basin, it is necessary to implement river dredging project in Daxihaizi reservoir downstream. It have three water conveyance way to choice, through comparing investment, land, construction, management and flood control, select a new built outlet sluice scheme in main dam of Daxihaizi reservoir. The scheme is feasible in economy and technology. According to the principle of vegetation water demand along lower reaches of Tarim river and reasonable ecological sluices number, analyse and protective vegetation area, discuss ecological water transport ways and open order of ecological sluices gate.
