河道生态环境需水量的计算方法众多,不同方法的适用性也不同;且根据不同生态环境的要求,生态需水量也有较大差别。本文采用Tennant法和水量平衡法进行阜阳城区河道的生态需水量分析,并按照最基本的生态要求和生态效果非常好的两种工况进行研究,确定在不同生态效果条件下的河道生态需水量。 There are many calculation methods of river ecological environment water demand, and the applicability of different methods are also different. According to the requirement of different ecological environment, the ecological water demand also has great difference. In this paper, the Tennant method and the water balance method were used to analyze the ecological water demand of the rivers in Fuyang City. According to the most basic ecological requirements and the two ecological conditions with very good ecological effects, the ecological ecological water requirements under different ecological effects were determined .
