随着人口继续向城市集中，世界将完全城市化，城市空间正在经历剧烈的演变。理解快速城市化背景下城市功能用地转换与扩展的空间格局，有助于我们从理论和实践层面更深入地把握城市空间演化的轨迹。以长春市中心城市为例，利用ESRI ArcGIS 9.3软件平台，采用叠置分析、转移矩阵和核密度估计等方法，分析了不同类型城市功能用地转换与扩展的时空特征。结果表明，不同功能类型的城市用地不断扩展和更替，城市空间结构不断演变。城市功能用地的转换与扩展表现出与同心带和扇形模式相似的特征，并在不同时期呈现出不同同心圆和方向的动态变化。该方法可以准确识别不同类型的城市功能用地，并探索城市空间结构的演变轨迹。这一研究将有助于协调城市不同功能空间的发展，优化未来的城市空间结构。
As populations continue to be concentrated in cities, the world will become entirely urbanized, and urban space is undergoing a drastic evolution. Understanding the spatial pattern of conversion and expansion of functional urban land, in the context of rapid urbanization, helps us to grasp the trajectories of urban spatial evolution in greater depth from a theoretical and practical level. Using the ESRI ArcGIS 9.3 software platform, methods, such as overlay analysis, transition matrix, and kernel density estimation, were used in order to analyze the spatiotemporal characteristics of different types of functional urban land conversion and expansion in the central city of Changchun. The results show that different types of functional urban land were often expanded and replaced, and the urban spatial structure was constantly evolving. The conversion and expansion of functional urban land show similar characteristics to concentric zone and sector modes and show dynamic changes in different concentric circles and directions at different periods. Our method can accurately identify the different types of functional urban land, and also explore the evolutionary trajectory of urban spatial structure. This study will help to coordinate the development of different functional urban spaces and to optimize the urban spatial structure in the future.
