【摘要】：随着科学技术的发展,城市化进程不断加快,城市的用地规模迅速扩大,城市土地利用中的矛盾日趋紧张,因此,必须进行合理有效地城市规划来引导和推进。为了合理规划土地利用,本文从城市规划角度出发,利用传统的元胞自动机模型,引入控制性详细规划层,构建城市规划元胞自动机模型。以无锡市区为研究区域,对其城市空间结构演变进行有效的动态模拟和预测。本文研究的主要工作包括：首先详细阐述了元胞自动机模型产生背景、构成和特点,根据元胞自动机自身特点和优点在模拟城市空间结构形态同样存在一些不足,如元胞空间尺度划分、城市元胞转换规则定义等；其次提出了从城市规划角度出发,将传统的城市元胞自动机模型改进为“自上而下”与“自下而上”相结合的城市规划元胞自动机模型思想,构建城市规划元胞自动机模型。介绍了模型构成要素组成、参数、规则、模型的评价指标等；再次运用城市规划元胞自动机模型,对无锡市城市空间结构形态进行动态模拟；最后根据城市发展按现有速度发展存在一些问题,提出了三种规划方案对对未来无锡城市空间结构进行分析和模拟,并运用聚类分析方法,对无锡市区47个镇、街道进行规划城市土地利用功能划分。在本研究中,将城市规划理论与元胞自动机原理相结合,构建了城市规划元胞自动机模型,模型算法简单、直观。应用城市规划元胞自动机模型对无锡市城市空间结构动态演变进行模拟尝试,在一定程度上促进了城市元胞自动机在城市空间结构中的应用研究,同时模型中设定的几种规划方案模拟城市空间形态,为城市规划工作者规定城市规划提供了一定的参考价值。
[Abstract]:With the development of science and technology, the process of urbanization is speeding up, the scale of urban land is expanding rapidly, and the contradiction in urban land use is becoming increasingly tense. Therefore, reasonable and effective urban planning must be carried out to guide and promote it. In order to plan land use reasonably, this paper, from the point of view of urban planning, uses the traditional cellular automata model, introduces the control detailed planning layer, and constructs the urban planning cellular automata model. Taking Wuxi urban area as the research area, the urban spatial structure evolution is simulated and forecasted effectively. The main work of this paper is as follows: firstly, the background, composition and characteristics of cellular automata model are described in detail. According to the characteristics and advantages of cellular automata, there are some shortcomings in simulating the shape of urban spatial structure. Such as cell space scale division, urban cell transformation rules definition and so on. Secondly, from the point of view of urban planning, The traditional urban cellular automata model is improved to the "top-down" and "bottom-up" urban planning cellular automata model idea, and the urban planning cellular automata model is constructed. This paper introduces the composition, parameters, rules and evaluation indexes of the model, and makes a dynamic simulation of the urban spatial structure in Wuxi by using the cellular automata model of urban planning. Finally, according to the existing problems in urban development, three planning schemes are proposed to analyze and simulate the urban spatial structure of Wuxi in the future, and 47 towns in Wuxi are analyzed by cluster analysis. Street planning urban land use function division. In this study, a cellular automata model of urban planning is constructed by combining the theory of urban planning with the principle of cellular automata. The algorithm of the model is simple and intuitionistic. This paper attempts to simulate the dynamic evolution of urban spatial structure in Wuxi by using the cellular automata model of urban planning, which to some extent promotes the application of urban cellular automata in urban spatial structure. At the same time, several planning schemes are set up in the model to simulate the urban spatial form, which provides a certain reference value for urban planners to stipulate urban planning.
