摘　　要：桂江流域具有降雨量大,汇流快,难预报的特点。利用EasyDHM模型建模,采用EasyDHM产流模型和马斯京根法汇流模型演算方法进行产汇流计算。经过参数率定,模型模拟的洪水具有较高的精度,同时,模型所率定的参数适用于验证期的洪水。对桂江流域比较重要的参数进行了对比分析,得出适用于桂江流域的一组参数。Guijiang Basin has characteristics of large rainfall ,fast runoff generation and difficult to forecast .First ,a model based on the Easy DHM is established .Then ,by using the runoff generation model of Easy DHM ,the Muskingum method ,runoff calculation can be made .After parameter calibration ,the flood is simulated with a high precision and it is suitable for the flood of the validation period .By analyzing the important parameters for the river basin ,a set of parameters suitable for the river basin has been concluded .
