摘　　要：运用常微模型平衡态制固定性规则，编制了定性制图的计算机程序，并将其用于数学生态常微模型上，通过计算机操作，绘制多参数定性分类图形，观察到平衡点的精确的局部定性，简化了复杂的经典定性计算．当平衡点难于从非线性常微模型计算时，仍能从图中观察到它的精确的局部定性．A computer, program of qualitative nomography with the rules of nomographic qualitative observations of equilibria in ordinary differential models is made and applied to the mathematical ecologic models. Under the computer, the graphics of multiparametric qualitative classifications of the model is drawn, from which the accurate local qualitative behaviour of the equalibria can be observed. It simplifies the complex classical qualitative caculations, even when the equilibria can not be easily caculated from the nonlinear ordinary model, its accurate local qualitative behaviours also can be observed.
