Abstract:

The overlooking landscape of a mountain city is not only the natural landscape resources given by the nature, but also an important part of urban characteristics. Now, with rapid urbanization, the mountain body is gradually integrated with urban construction, forming the spatial characteristics of a mountain city. However, with the development of urban construction, the relationship between the city and the mountain gradually changes. The mountain landscape could be constantly changed during extensive urban construction, and the overlooking landscape of the mountain city will be disappeared in tall buildings and dense blocks. When people look far away, the green mountains will been gone, replaced with dense and airtight facade of high-rise buildings. Therefore, the overlooking landscape of a mountain city needs to be protected through appropriate methods. Taking Jinan city center as an example, this paper explores the rules of the evolution of architectures constructed based on the controlling zones and develops a spatial evolution model of mountain city by combining Cellular Automata theory and Multi-Agents theory which is called Overlooking Space Cellular Automata model (OSCA). We also use some data processing platforms such as GIS, to analyze and modify the results and discuss the developed models of urban spatial structure in a more intuitive way. Finally, we put forward strategies for future spatial development in mountain cities in order to protect or control the overlooking landscape of mountain cities. The OSCA model theoretically combines cellular automaton theory and multi-agent theory and technically integrates NetLogo simulation platform and ArcGIS 3D display platform, which is very innovative. Our research results show that the OSCA model can realize the dynamic evolution of a mountain city’s overlooking landscape and predict the future growth mode and development and construction mode of mountain city's overlooking space evacuation. It provides important theoretical and application values to guide urban planning and control the development of urban space. Although this study cannot bring all the complex elements into the model, it still provides reasonable evacuation suggestions for overlooking space according to the simulation results. We also put forward some solutions for the follow-up study on urban dynamic model construction and provide reasonable suggestions for the development of urban space and urban structure in future.
