摘　　要：通过对潼塘、大西滩、五里牌、坑口、龙家山站流量测次精简引起的误差对新安江三水源预报模型影响的分析,论述了流量测次精简误差对洪水预报的影响,提出了流量测次精简误差与洪水流量预报误差之间的关系。对《水文巡测规范》(SL195-97)的精度指标进行了论证。The effects of reducing discharge measurement times on flood forecasting by using Xinan-jiang Model are analyzed based on the practical data from Tongtang,Daxitan,Wulipai,Kengkou and Longjiashan gauging stations.Meanwhile,the relation between the error of computed discharge from re-ducing number of measurements and the error of flood forecasting has been given.The precision index in《Standard of Hydrological Research》has also been discussed and proved.
