为了对襄阳市主要河流生态基流进行估算,对常用的几种水文学计算方法进行总结,结合资料获取情况,选取Tennant法、7Q10法、90%保证率法和最枯月平均流量法对襄阳市4条代表河流控制断面的生态基流进行计算.在对计算结果进行对比和分析的基础上,结合河流生态需水要求,确定其生态基流的推荐值.对于缺乏逐日径流序列资料的河流,考虑每条河流的实际特征,结合上述4条代表河流的计算结果,对其生态基流进行估算.计算结果可为襄阳市水资源的合理开发利用和水生态文明建设提供依据.
The Estimation of Ecological Base Flow of Main Rivers in Xiangyang City Based on Multiple Hydrological Methods
As one of the important characterizations of river ecological water requirement,the ecological base flow is necessary.So the Tennant method,7Q10 method,90% reliability method and the most withered month average flow method were chosen to calculate the ecological basic flow of the four representative rivers in Xiangyang City.The recommended value of the ecological base flow was determined after comparing with the results and considering the river ecological water requirement.As for the other rivers that lack daily runoff series data,considering the actual features of every river and the calculation results of the four representative rivers,the recommended ecological base flow of the other major rivers was determined.The calculation results may serve as a guide for the reasonable utilization of water resources and ecological civilization construction of Xiangyang City.
