首先对河道内生态需水计算方法进行了研究，采用Tennant生态环境状况评价等级标准对常用的五种生态需水量计算方法进行了评价。其次，分析了河流受降雨、污染物、水生生物三大因素的影响条件下的状态变化。将所研究的计算方法应用与丰乐河生态需水量计算。结果表明，丰水期（5－9月）河道生态需水量可采用多年同期平均流量的65％～75％计算；枯水期（10月－翌年4月）生态需水量可采用多年同期平均流量的40％～60％。实践证明，研究结果对于河道生态需水量计算具有重要参考价值。

The calculation method of river ecological water requirement at home and abroad are studied in this paper by using the Ten‐nant ecological environment evaluation grade standard to evaluate the five kinds of commonly used river ecological water requirement calculation methods .Secondly ,the change of the river influenced by the three factors :rainfall ,pollutants ,aquatic organisms ,is an‐alyzed .The calculation method of research is applied to calculate the Fengle River ecological water requirement .The results show that the ecological water requirements is 40% ~60% (can be applied from May to September) and 65% ~75% (can be applied from October to next April) of the mean flow of many years in the same period .The research result has an important reference value for river ecological water demand calculation .
