佛子岭水库流域预报根据雨量值,优选9站平均值代替流域14站平均值作为流域预报根据雨量值。经用佛子岭水库流域1983-2004年25场次降雨过程计算分析,9站组合比原先5站组合相对误差明显减小,是提高水情预报精度的重要举措。优化组合思路综合考虑了各站点交通、通讯等条件,对相关流域进行雨量站点科学规划及提高流域预报雨量根据值预报精度提供参考,具有重要的现实意义。
For the prediction of watershed of Foziling Reservoir, the average value of 9 stations should be used instead of the average of 14 stations as the forecast of river basin based on the rainfall value. Based on the calculation of 25 rainfall events in Fuziling Reservoir watershed from 1983 to 2004, the relative errors of 9 stations and 5 stations were significantly reduced, which is an important measure to improve the accuracy of hydrological forecast. Optimization of combination of ideas Considering traffic, communication and other conditions of all stations, it is of great practical significance to carry out scientific planning of rainfall stations in relevant basins and to improve rainfall forecasting of watersheds according to their forecasting accuracy.
