摘要
对引江济渭入黄工程水源区,汉江上游的生态环境需水量进行了一定的研究探讨。生态环境需水量的计算存在许多种方法,根据长江流域的特点和实际条件,初步确定选用Tennant法、Q90法和湿周法等3种方法来计算引江济渭入黄工程水源区生态环境需水量,并通过比较综合确定最终的生态环境需水量。
In this paper, the eeo-environment water demand in the upper-stream of Hanjiang River was studied. We used 3 methods (Q90 method, Tennant method and Wet perimeter method) to calculate the eco-environment water demand, and then we give the recommended water volume based on these results.
