【摘要】：針對(duì)傳統(tǒng)水文學(xué)方法計(jì)算生態(tài)流量時(shí)采用受人類活動(dòng)影響較大的實(shí)測(cè)徑流系列而導(dǎo)致計(jì)算結(jié)果偏小的問題,提出了基于長(zhǎng)系列降水徑流資料分析的改進(jìn)7Q10法,并將其應(yīng)用于灤河上、中、下游代表水文站的最小生態(tài)流量的計(jì)算中。結(jié)果表明:灤河河道徑流量在1979年后受人類活動(dòng)影響較為劇烈;與傳統(tǒng)方法相比,改進(jìn)7Q10法計(jì)算的最小生態(tài)流量結(jié)果更符合實(shí)際。
[Abstract]:In view of the problem that the measured runoff series which are greatly influenced by human activities are adopted in the calculation of ecological discharge by traditional hydrology method, the improved 7Q10 method based on the analysis of precipitation and runoff data of long series is put forward. It is applied to the calculation of the minimum ecological flow of the hydrological station in the middle and lower reaches of the Luanhe River. The results show that the runoff of Luanhe River is greatly affected by human activities after 1979, and compared with the traditional method, the minimum ecological discharge calculated by the improved 7Q10 method is more realistic.
