摘要

由于西南地区地形地貌复杂多变,许多地区缺乏实测洪水资料,给水利工程建设带来诸多不便。为了解决上述问题,为水利工程建设提供参考资料,基于西南地区11个流域66个水文站点的设计洪峰流量(Q_p)和集水面积(F)资料,通过统计分析,分类研究了西南地区Q_p与F之间的关系。结果表明:嘉陵江流域、沱江流域、涪江流域、岷江流域、澜沧江流域Q_p与F之间能较好地满足线性关系;大渡河流域、青衣江流域、雅砻江流域Q_p与F之间指数关系较显著;金沙江流域、怒江流域和雅鲁藏布江流域Q_p与F之间幂函数关系较好。研究成果可为无资料地区建立流域Q_p与F之间的相关关系提供参考。

Abstract

The lack of flood measurement data due to complex and changeable landform brings about many inconveniences to hydro-project construction in southwest China. According to data of design flood peak discharge (Q_p) and collecting area (F) at 66 hydrologic stations in 11 basins in the southwest region of China, the relationship between Q_pand F is researched by statistical analysis. Results show the Q_p-F relationships in the Jialing River basin, Tuojiang River basin, Fujiang River basin, Minjiang River basin and Lancang River basin follow linear relationship; while in the Dadu River basin, Qingyi River basin and Yalong River basin, the Q_p-F relationships match well with exponential relationship; and in the Jinsha River basin, Nujiang River basin and Yarlung Zangpo River basin the relationships conform well to power function. The research results offer reference for obtaining the Q_p-F relationships in ungauged river basins.
