Under the new circumstances of global economic integration, industrialization and the urbanization promote the rapid development of IT industry, especially ’information expressway and internet’-based on computer and remote-sensing technology among big cities gets faster development. Information network has great influences on the formation and the development of urban agglomeration. The network of urban agglomeration is not only the most superior model in material flow between cities and countries, but also is the optimized urbanization model on the process of formation of urban agglomeration. The network organization of urban agglomeration is being perfected and has all kinds of models in the area of well-equipped infrastructure. The article focally discusses the following issues: ①The conception and the spatial distribution of network in urban agglomeration. ②The four network models of urban agglomeration: core region network, towns of dumbbell network, multiple nuclei network, corridor-type network.③The influences of network on the flows of people, material and information in urban agglomeration. Based on the analysis on the reasonability of network in view of spatial organization, the authors try to adjust the contradiction between the planned economic activities and disorderly management.
