摘　　要：根据分形理论,借助ArcGIS研究连云港1980—2005年城市用地形态和结构的演化特征。研究表明,连云港城市土地形态及各职能用地存在明显分形特征,且符合城市用地分维包容原理。在区域经济发展、城市化进程和城市规划等共同作用下,整体城市用地形态维数在逐渐上升,说明城市分形发育程度还不高。城市用地在自组织优化过程中还存在公共绿地、工业用地发展的局部退化问题。The fractal theory and ArcGIS soft are employed to study the characteristics of evolution of urban morphology and structure in the City of Lianyungang. The results show that the fractal characteristics of urban morphology and structure are clear and the dimension inclusion theory is confirmed. From the viewpoint of spatial-temporal change, the fractal dimension of the whole urban morphology tends to be increasing, and the causes for such a trend can be attributed to the development of urban economy, the process of urbanization and city planning. Moreover, a few questions in land structure have also been discovered, including the centralized distribution of green land and the scattering of industrial land.
