| 摘 要： | 【目的】确定恰当的流域汛期,为水库的防洪安全奠定基础,同时为水资源的优化调度提供决策依据。【方法】基于相关分析方法,采用千河流域31年的日均流量资料,对流域不同时段的径流自相关性进行研究,根据其显著性差异确定千河流域的汛期和主汛期。最后从水文气象学原理出发,结合西北地区的气候特征分析,对汛期和主汛期的划分结果进行验证。【结果】确定千河流域的汛期为5月下旬至10月上旬,与千河流域主要降雨期一致;主汛期为07-01-08-31,与千河流域的暴雨峰值期一致;说明汛期、主汛期的划分结果是合理的。【结论】基于相关分析法的汛期划分研究,方法简单直观,物理概念清晰,可为千河流域冯家山水库的安全运行及水资源调度决策提供参考。
