中文摘要：

以城市功能的演进历程为城市联系研究的新视角，构建了城市联系的城市功能网络分析框架。其中，城市功能网络由功能要素、联系通道和作用载体三部分组成，是城市功能在多元、差异和互补的基础上通过有形或无形的联系通道，以实体或虚拟的空间“流”为作用载体形成的城市功能空间网络化结构。基于城市功能网络的概念内涵，以珠江三角洲城市功能网络的演化历程为实例，演示了该地区城市联系的演化历程和空间特征，探索了城市联系的城市功能网络分析视角。

英文摘要：

As an important property of city, city functions in different periods differ in forms, intensity and spa- tial characteristics from the preindustrial age to the postindustrial age. City function experienced from a single and simple function to various, messy and homogeneous functions and then to the diversified different and complementary networked evolution process. This article tries to open a new view angle of city linkage re- search based on the evolution of city function by constructing an analytical structure of city functional net- work. The city functional network in the postindustrial period consists of three components of function ele- ments, linkage channel and role carrier. On the basis of diverse, different and complementary city function and through the tangible or intangible linkage channel and taking the entity or virtual spatial flow as the role carti- er, forms spatial network structure of city functional network was formed. Based on the evolution process of city function and the concept and connotation of city function network, the article took the evolution of city function network in the Zhujiang River Delta as an example, and reconstructed the history and space features of city linkage in the region and finally constructed a new analytical perspective of city function network on city linkage researches.
