摘　　要：为科学确定秦岭北麓典型河流沣河的生态流量,保障生态环境安全,合理开发秦岭北麓水资源,基于沣河秦渡镇水文站1953~2013年连续实测月径流资料,使用Tennant法、90%保证法、最枯月平均流量法、Tessman法、年内展布法、Texas法、典型水文频率年法及NGPRP法8种水文学方法计算沣河生态流量值。通过分析对比结果表明,Texas法在满足程度、水文节律方面表现较好,最终推荐Texas法作为沣河的生态流量计算方法,并给出生态流量推荐值。研究结果可为秦岭地区水资源的开发利用提供科学依据,对区域河流生态系统健康也具有重要意义。In order to scientifically determine the ecological flow of the Fenghe River,a typical river in the northern foothills of the Qinling Mountains,ensure the safety of the ecological environment,and rationally develop water resources of the northern foothills of the Qinling Mountains,eight hydrological methods,including the Tennant method,90%guarantee method,method of average discharge in the driest month,Tessman method,annual distribution method,Texas method,typical hydrologic frequency year method and NGPRP,were used to calculate the ecological flow value of Fenghe River using the continuously measured monthly runoff data of the Hydrological Station of Qindu Town in Fenghe River from 1953 to 2013.Through analysis and comparison,the Texas method performed well in terms of satisfaction degree and hydrological rhythm.Finally,the Texas method was recommended as the calculation method of ecological flow in Fenghe River,and the recommended value of ecological flow was given.The results of this study can provide a scientific basis for the development and utilization of water resources in Qinling Area,and are also of great significance to the health of regional river ecosystems.
