| 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: | The ecological flow obtained from traditional hydrologic methods that adopt measured runoff series affected by human activities is lower than its actual value. In order to solve this problem, an improved 7Q10 method is proposed based on analysis of long series of rainfall and runoff data, and is used to calculate the minimum ecological flow at representative hydrological stations upstream, midstream, and downstream of the Luanhe River. The results indicate that runoff in the Luan River has been significantly affected by human activities since 1979, and the minimum ecological flow obtained from the improved 7Q10 method is more reasonable than that obtained from the traditional method. |
