【摘要】：城市形态是不同历史时期城市物质文明和精神文明发展的积累与沉淀,并随着城市的发展而不断演变。目前我国正处于经济高速增长和城市快速发展的过程中,其中城市人口剧增导致了城市用地增加、城市空间拓展以及城市结构重组,进而促使了城市形态的无序演变。与此同时,也产生了一系列的城市问题,所以对城市形态演变进行研究是引导城市健康有序发展的重要手段之一本文以空间句法为研究的主要理论基础和技术方法,以定量的方式来描述合肥城市空间形态动态发展的深层次特征及基本规律。研究选取空间句法理论中与城市空间形态关系密切的指标参数,即全局整合度、局部整合度、连接度、可理解度和空间智能度,构建六个不同时期的合肥市中心城区空间分割轴线地图,通过对比各时期相关测度值的变化,以此来说明城市内部空和外部空间形态的发展特征及其影响因素,即分析自组织要素和他组织要素之间的关系。另外,论文引进城市紧凑度这个衡量城市形态的重要指标,以辅助城市空间形态的外向发展研究,希望更为全面的解释城市形态的发展。最后,总结长期以来合肥中心城区城市空间形态的演变过程、特征、机制、演化动因以及当前所面临的问题,提出今后合肥城市空间形态优化策略及发展模式,为合肥城市空间的可持续发展提供了全新研究视角和思路,同时可为规划管理部门提供决策的数据支持与借鉴。
[Abstract]:Urban form is the accumulation and precipitation of material civilization and spiritual civilization in different historical periods, and evolves with the development of city. At present, our country is in the process of rapid economic growth and rapid urban development, among which the rapid increase of urban population leads to the increase of urban land use, the expansion of urban space and the reorganization of urban structure, thus promoting the disorderly evolution of urban form. At the same time, there are a series of urban problems, so the study of the evolution of urban form is one of the important means to guide the healthy and orderly development of the city. This paper describes the deep level characteristics and basic laws of the dynamic development of the urban spatial form in Hefei by means of quantitative analysis. The index parameters of spatial syntax theory which are closely related to urban spatial form, namely global integration degree, local integration degree, connectivity degree, comprehensible degree and spatial intelligence degree, are studied and selected. Construct six different periods of urban space segmentation axis map of Hefei, through comparing the changes of relevant measurement values in each period, to explain the development characteristics and influencing factors of urban inner space and outer space form. That is, to analyze the relationship between self-organizing elements and other organizational elements. In addition, the paper introduces the city compactness, which is an important index to measure the urban form, to assist the outward development research of the urban spatial form, hoping to explain the development of the urban form in a more comprehensive way. Finally, the paper summarizes the evolution process, characteristics, mechanism, evolutional motivation and current problems of the urban spatial form in the central urban area of Hefei for a long time, and puts forward the optimization strategy and development mode of the urban spatial form in Hefei in the future. It provides a new perspective and train of thought for the sustainable development of urban space in Hefei, and can also provide data support and reference for planning and management departments.
