根据抚仙湖的特点，提出了一个二维分层积分数值模式。应用该模式探讨了抚仙湖内波及上、下层流场特征。计算结果表明：在无旋风场作用下，内波在空间上作４２．５ｈ周期性旋转；在有旋风场作用下，抚仙湖北部湖区存在转向相反的双层水平环流，并且上层的反时针环流主要是由湖区正旋度附加风场作用而形成的。模拟结果与观测事实吻合较好。
According to the characteristics of Fuxian Lake, a two-dimensional layered integral numerical model is proposed. Using this model, the characteristics of wave propagation in upper and lower laminar flow in Fuxian Lake are discussed. The calculation results show that the inner wave rotates periodically in the space of 42.5h under the effect of no cyclone field. Under the action of the cyclone field, there exists a double horizontal circulation with opposite turn in the northern part of Fuxian Lake, and the counterclockwise Circulation is mainly formed by the role of additional curvilinear wind in the lake area. The simulation results are in good agreement with the observed facts.
