摘要
通过分析旬降雨、旬初土壤蓄水状态、旬径流信息之间的关系,借鉴短期降雨径流相关模型的思想,建立了一个旬降雨─旬土壤蓄水量─旬径流的非线性相关模型。将该模型应用于大伙房水库流域,模拟预测结果令人满意,结果表明该模型简单,可操作性强。将为应用美国的GFS预报系统和中国气象局的213模式10～15d降雨预报信息,预报旬径流量提供一个有效方法。
A non-inear correlation model is presented based on correlation between the rainfall and the runoff of every ten days. The model is apPlied for the Dahuofang Reservoir basin by use of the observed data. The result of simulation and calculation is satisfactory. The results shows that the model is simple and feasible. It will provide an effective tool to forecast the runoff of every ten days with the advance information of rainfall forecasted by GFS （Global Forecasting System） and the T213 model of China Meteorological Administration.
