摘要
建立了变系数扩散的一维自组织非线性气候模型，取热流输运系数为Ｄ（ｘ）＝Ｄ０（１－ｘ２）（ｘ＝ｓｉｎθ，θ为纬度），运用超熵产生理论讨论了ＣＯ２浓度增加与气候突变的稳定性关系，得到突变时ＣＯ２浓度的临界值，所得结论基本上符合近代气候变化的时间尺度特征，也与有关文献的结论一致．
A one dimensional nonlinear self organized climate model with varing diffusion coefficient is developed.By taking D(x)=D 0(1-x 2)(x=sinθ,θ is latitude)as the diffusion coefficient,the relations between increase of CO 2 concentration and abrupt climate warming are discussed by using excess entropy production theory,and the critical value of CO 2 concentration is derived when abrupt climate warming occurs.The results are basically in agreement with the time scale character of modern climate change and with the conclusions of related references.
