摘　　要：本文以2011年6月以来彭水和银盘水电站流量及流域面雨量数据为基础资料,对银盘—彭水区间流量与面雨量变化关系进行了分析,并从该区间流量的形成规律出发,探寻对区间产流作用明显的影响因素,采用前一日区间流量、当日面雨量等预报因子建立分月的银盘—彭水日均区间流量预报模型。结果表明,利用回归模型求解,能够较为准确地预测区间产流的量级。Based on the data of runoff and area rainfall of Pengshui and Yinpan Hydropower Stations since June 2011,this paper analyzes the relationship between the runoff and area rainfall in Yinpan-Pengshui interval,and explores the obvious influencing factors on the interval runoff from the formation law of Yinpan-Pengshui interval flow,and establishes a monthly daily average interval flow forecasting model of Yinpan-Pengshui by using forecasting factors such as the previous day’s interval flow and the current area rainfall.The results show that the order of interval runoff can be accurately predicted by using regression model.
