本文采用引力模型、城市流模型，结合GIS空间分析方法，分析了近十年滇中城市群城市空间联系的时空演变。研究表明：（1）滇中城市群城市空间联系强度逐渐增加，区域差异明显，联系强度总体偏低。（2）城市群空间联系方向以昆明为中心呈圈层式向外辐射状及沿南部、东北交通干线呈轴线式空间拓展，西北部空间联系强度最弱。（3）城市经济发展水平与交通状况对区域空间联系强度影响较大，通过产业结构转型及交通道路网完善，可以实现城市群的协调发展。%By applying the economic relation intensity model, urban lfow model and GIS spatial analysis methods, this article studied the temporal evolution of spatial connection among cities of Dianzhong urban agglomeration in recent 10 years. The results show that: (1) The spatial connection among cities of Dianzhong urban agglomeration has been gradually strengthened and shows distinctive difference in different urban. The whole spatial connection is still low. (2) The spatial connection direction appears in a circle shape, which radiates externally around Kunming and expands along south and northeast trafifc arteries. The weakest spatial connection of Dianzhong urban agglomeration is in northwest area. (3) The economic development level and trafifc conditions have a great impact on the degree of spatial connection. Industrial structural transformation and traffic network improvement can promote Dianzhong urban agglomeration developing coordinately.
