摘要
根据流域的产、汇而特性，总结了以往对该流域的洪水预报模型研究与探索工作的经验，采用了以雨量站控制面积划分单元的分单元计算方法，较好地解决了预报精度问题，７年１３场大洪水（洪峰流量大于７０００ｍ￣３／ｓ）全部合格，一般洪水的合格率也达到９５．６％以上，成果比较满意。
According to charecteristics of runoff yield and afflux in the basin,analysis of flood prediction mod-el and experince are summarized.Computation from catchment area of each precipitation station is used to getaccurate flood prediction. The thirteen times of catastrophic floods in seven years(discharge of peak flood ismore than 700Om￣3/s)are all predicted accurately. Accruacy of ordinary flood is up to 95.6%with satisfactory resuIts.
