摘要

从干旱区台兰河流域存在的环境问题出发，在确定流域平原区生态环境需水类型的基础上，构建了台兰河流域平原区生态环境需水定量模型，估算了流域平原区生态环境的规模。计算结果表明，台兰河平原区最大生态环境需水量为4.146×108m3，最小生态环境需水量为2.372×108m3，最适生态环境需水量为2.983×108m3，分别占台兰河平原区水资源总量(8.121×108m3)的51.05%，29.21%和36.73%。在不考虑河流输沙需水量的情况下，台兰河河流生态环境需水量平均为1.440×108m3。在考虑输沙需水量的情况下，河流生态环境需水量平均为2.604×108m3。明确了在确定流域生态环境需水量时，必须考虑研究区环境状况和生态保护目标，从而在不同区域和用水部门间进行调配，并针对流域不同的生态系统状况和对应生态系统类型确定了面向生态的水资源合理配置方案。

Abstract

In view of the present main environmental problems in the Tailan River basin

based on the types of eco-environmental water requirement for river basins

quantification model of eco-environmental water requirement for plain regions of Tailan River basin is established and the scale of eco-environmental water requirement is estimated.The results indicate that the maximum of eco-environmental water requirement is 4.146×108m3

the minimum is 2.372×108m3 and the optimum is 2.983×108m3

which take 51.05%

29.21% and 36. 73% of the regional watergross

respectively.Average eco- environmental water requirement in Tailan River is 1.440×108m3when excluding water requirement of sand transportation

and 2.604×108m3if considering the water requirement of sand transportation.According to environmental status and the aim of ecological protection

eco-environmental water requirement in river basin can be ascertained.Consequently

water resources use will be allocated in different area and different usage department

and the rational scheme of water resources in ecology will be confirmed based on the different status of eco system and corresponding types of ecosystem in arid in land river basin.
