摘要
本文利用丰满水库1959～2005年水位资料,流域降水资料,丰满水库放流资料,探讨了水库水位变化与流域降水的关系。利用统计学方法找出时空相关因子,建立数学模型,并对方程做对比检验。得出结论:采用独立站点的空间分布因子和综合站点的降水时间分布因子建立的方程模式,较为适合丰满汛期径流水位预报,径流水位预报的准确率有所提高。
According to the data of water level,basin precipitation and flow discharges from the year of 1959 to 2005 in Fengman Reservoir,the relationship between water level change and basin precipitation were analyzed.The time-space factors were found out through statistical methods,the mathematical mode was built,and comparative tests for the equations were carried out.The results show that equation models built by space distribution factors in independent station and precipitation distribution factors in integrated station are suitable for forecasting flood runoff level in Fengman Reservoir,which improve the forecast accuracy of runoff level.
