【摘要】：針對傳統(tǒng)水文學方法計算生態(tài)流量時采用受人類活動影響較大的實測徑流系列而導致計算結果偏小的問題,提出了基于長系列降水徑流資料分析的改進7Q10法,并將其應用于灤河上、中、下游代表水文站的最小生態(tài)流量的計算中。結果表明:灤河河道徑流量在1979年后受人類活動影響較為劇烈;與傳統(tǒng)方法相比,改進7Q10法計算的最小生態(tài)流量結果更符合實際。
[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.
