摘　　要：流域枯水期径流影响和制约着流域水资源开发利用的整体效益,对年内较长时间存在枯水径流的流域进行径流预报分析研究对流域内取用水工程运行、调度具有重要参考作用。文章以实例数据为依据,对伊春河流域的枯水径流特征进行了简要概括,采用线性回归法对历年枯水径流做了拟合分析,得出回归方程,拟合和实例预报精度基本满足要求,本次数据系列选择预报因子较少,仅供参考。Runoff affects and restricts the overall benefit of water resources development and utilization in the low water period of the basin.The runoff prediction and analysis of the watershed with dry water runoff for a long time in the year has an important reference role for the operation and regulation of the water intake project in the basin.Based on the example data,the characteristics of low water runoff in Yichun River Basin are briefly summarized in this paper.The linear regression method is used to fit and analyze the dry water runoff over the years,and the regression equation is obtained,and the precision of fitting and forecasting examples basically meets the requirements.The factors of this data series are just a few,only for reference.
