摘要
在计算河道内生态需水量方面,传统Tennant法存在局限性。基于河流功能的量化计算,从计算时段标准、特征流量、综合影响因子等方面对Tennant法进行改进,提高了模型的实用性。用改进的模型计算黄河花园口、高村、艾山三站的生态需水量,并用其他方法的计算结果进行了验证。结果表明:改进的Tennant法计算结果更为合理,兼顾了生态需水的众多影响因素,有利于生态保护和维持河道持续健康发展。
In the calculation of the in stream ecological water requirement,the traditional Tennant method has limitations.In consideration of the river function quantitative calculation,the improved Tennant method was proposed for increasing the practicality of the model from the aspects of calculation time standards,flow features and comprehensive influence factor.On the basis of the improved method on ecological water requirement calculation on three hydrological stations at Huayuankou,Gaocun and Aishan,the model is verified by the calculation results of other methods.After the comparison between this method and other correlation methods,the results show that the improved method is more reasonable and has taken account of the many affecting factors of ecological water requirement.This improvement is helpful to protect the ecology and maintain the sustainable development of the river.
