【摘要】：针对传统水文学方法计算生态流量时采用受人类活动影响较大的实测径流系列而导致计算结果偏小的问题,提出了基于长系列降水径流资料分析的改进7Q10法,并将其应用于滦河上、中、下游代表水文站的最小生态流量的计算中。结果表明:滦河河道径流量在1979年后受人类活动影响较为剧烈;与传统方法相比,改进7Q10法计算的最小生态流量结果更符合实际。
[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.
