Research On The Dynamic Mechanism Of Spatial Form Evolution In The Neoteric Open Cities Basing On The Multi Agent Simulation Technology

The neoteric open cities as an important part of China's historical and cultural heritage, due to its special geographical location and socio-historical background, focus reflects the cultural conflict, spatial shape and regularity of urban development, urban spatial form evolution and dynamic mechanism in research has important research value mechanism. Research studies on domestic inception urban spatial morphology evolution of dynamic mechanism stays on the list of the relevant factors, the study of the mechanism of action of each dynamic way, the role of the depth of mutual relations is not deep enough, especially the lack of quantifiable. In recent years, the rise of multi-agent simulation approach provides for the academic study of a new perspective: it is based on the theory of complex systems "bottom-up" perspective, by a large number of micro-simulation to study the macroscopic behavior of individual law system, and thus bring new research opportunities.Firstly, the concept of urban space forms are defined, respectively, on the Opening of urban spatial morphology evolution of domestic and foreign research and application of multi-agent simulation in the field of urban spatial morphology are outlined. Secondly, the city set up the whole story briefly Opening and distribution characteristics, summarized the coast, the general process of the early years of urban space along the river morphology and evolution of the northeastern region, on this basis, summed up the main dynamic mechanism of urban spatial morphology evolution inception. Then simulation applications in urban spatial morphology evolution mechanisms through the introduction of multi-agent, for the following structures of the Tianjin urban spatial morphology evolution model provides a theoretical basis. By analyzing the evolution of modern commercial center of Tianjin city dynamic mechanism to create multiple multi-agent simulation model to simulate the evolution of modern business center in Tianjin city together under the dynamic mechanism to seek the facts and urban space development dynamic mechanism most consistent combination regimen, in order to dynamic mechanism constituted as a path discovery mechanism, and try to force the size of the dynamic mechanism by changing the number of possibilities to explore urban spatial morphology evolution. Finally Comments on the advantages of multi-agent simulation applications: it can be characteristic of the micro and macro environment clever individual contact, making clearer, quantitatively understand the dynamic mechanism for the evolution of modern urban spatial morphology influence and role in Tianjin possible; further analysis the difficulties and disadvantages of multi-agent simulation study, and the evolution of urban spatial morphology Opening provide outlook.
