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.
