摘要
由于湿周法在确定突变点中存在主观性的缺陷,而最大曲率法可客观的确定河流生态基流,避免了主观性。在湿周法的基础上,研究了河流生态基流的概率分布,同时研究了径流特征值和生态基流之间的关系,为河流生态需水的预测提供了解决方法。
As the wetted perimeter method has the subjective shortcoming in determination of the inflection point, however, the method of maximum can determine river ecological basic flow objectively to avoid the subjectivity concerned, the probability distribution of river ecological basic flow is then studied on the basis of the wetted perimeter method. At the same time, the relationship between the characteristics of runoff and the ecological flow is studied as well, which provide a method to predict the ecological water demand of river.
