近60 a潘家口水库控制流域径流情势研究

Runoff Situation in Panjiakou Reservoir Watershed over the Past 60 Years

基于所选取的代表性水文站点和长系列天然与实测年径流量系列,分别采用Kendall非参数检验法、Hurst指数法、Mann-Whitney-Pettitt法分析了潘家口水库控制流域3个代表性水文站点的天然、实测年径流量系列变化的趋势性、持续性和突变性,研究结果可为优化引滦工程水资源调度工作提供技术参考。

Based on selected representative hydrological stations and long series of natural and measured annual runoff data,the trends,persistence and abrupt changes in the variations of natural and measured annual runoff series are analyzed for three representative hydrological stations in Panjiakou Reservoir watershed using the Kendall non-parametric test,Hurst exponent method,and Mann-Whitney-Pettitt test.The aim is to provide technical references for optimizing the water resources scheduling of Luanhe River Water Diversion Project.
