摘要
利用1980—2016年郭家屯水文站和三道河子水文站逐月流量数据,综合运用QP法、Tenant法、频率曲线法、典型水文频率年法、NGPRP(norther great plains resources program)法、近10年最枯月月平均流量法、TEXAS法等7种水文学方法,根据滦河丰水时段和枯水时段内不同月份径流量的特点,精细划分出相关断面每个月份生态基流取值的上限和下限,对相关断面的生态基流量进行测算和分析,得出三道河子断面生态基流取值1.10~6.06 m^(3)/s为宜,郭家屯断面生态基流取值0.78~5.66 m^(3)/s为宜。用上述确定的生态基流值对2个断面37年的逐月流量进行检验,结果表明:2个断面37年大部分月份生态基流都能得到保证,12月、1月和2月2个断面生态基流保证率相对较低,而对于生态基流保证率低的月份,建议通过合理划分水权、科学调度工程、建立监控体系等措施保障生态用水。
The excessive use of water resources, not only affects the sustainable development of the river basin or region but also destroys the water ecological environment to a certain extent.Therefore, it is necessary to conduct scientific accounting and regulation research on water resources, which not only guarantees the sustainable use of water resources but also maintains the healthy life of rivers, by studying the ecological base flow of rivers and ensure the maintenance of a certain flow in the river.The Luan River surrounds Beijing and Tianjin from the northwest to the southeast.It is an important and irreplaceable water conservation area and ecological support area for Beijing and Tianjin.It is also responsible for the important task of supplying water to Tianjin and Tangshan.As an important water resource link, the study of the ecological base flow of the Luan River is essential to ensure the healthy life of the Luan River.The current ecological base flow research of Luan River lacks a variety of hydrological methods to comprehensively analyzing the ecological base flow.Therefore, 7 hydrological methods are used to calculate and analyze the ecological base flow of the typical section of Luan River.Monthly flow data of the Guojiatun hydrological station and Sandaohezi hydrological station from 1980 to 2016,the QP method, the tenant method, the frequency curve method, the typical hydrological frequency year method, the NGPRP(norther great plains resources program) method, and the driest monthly average flow in the past 10 years are used comprehensively.According to the characteristics of the runoff of different months in the Luan River during the flood period and the low water period, the upper and lower limits of the ecological base flow value of the relevant sections in each month are finely divided.The outcomes show that the ecological base flow value of the Sandaohezi section is from 1.10 m^(3)/s to 6.06 m^(3)/s, and the ecological base flow value of the Guojiatun section is from 0.78 m^(3)/s to 5.66 m^(3)/s.T
