建立了湖泊三维风生流的隐格式差分模型，通过对该模型计算稳定性的分析发现，它的时间步长的取值具有较大的灵活性．该模型波用于武汉市墨水湖的民生流模拟，实例计算表明该模型计算结果合理，能较好地反映湖泊风生流的流态特征．
The implicit difference model of three-dimensional wind flow in lakes is established. By analyzing the stability of the model, it is found that the value of time step has great flexibility. The model wave is used to simulate the livelihood of the Lake in Wuhan, and the calculation results show that the model is reasonable and can reflect the characteristics of the flow in the lake.
