摘　　要：GWLF(Generalized Watershed Loading Function)模型是一个半分布式、半经验式的流域负荷模型。它能够利用GIS及RS提供的空间数据,在中型尺度流域的范围内进行非点源污染负荷估算,模型比较适合于数据量少,参数相对缺乏的地区。重点介绍了GWLF模型的污染物负荷估算的原理,同时将GWLF模型应用于天津市于桥水库流域,利用沙河流域1999年水量、水质数据进行校准,初步估算出于桥水库上游流域的非点源负荷。GWLF(Generalized Watershed Loading Function)model is considered to be a combined distributed/ experienced watershed loading model.It is used to estimate non-point source pollution in the medium-sized watershed using spatial data,and the model is applicable to region which is lack of data and parameters.the theory of model was focused on estimating non-point source pollution,and the model was applied to Yuqiao Reservoir watershed in Tianjin.It was calibrated using Shahe River s stream flow data and water qua...
