摘要
应用消退曲线超渗产流模型与垂向混合产流模型计算的日土壤含水量和蒸发量作为干旱指标划分重庆市7个流域的干旱等级,评定结果与实际情况吻合。通过实例应用对比,垂向混合产流模型较合理。
Based on the vertically mixed runoff model and the excessing runoff producing model with the declining curve, evaporation and soil moisture content were calculated. Then, these two variables were used as drought indexes to divide drought grades of 7 basins in Chongqing City. Calculated results accord with the actual situation. By comparison, the results show that vertically mixed runoff model is more suitable for Chongqing City.
