ABSTRACT
摘要
As an important part of urban space, street space has become the urban living place where multifunctional activities happen with the development of history. based on the role and position of the street space in cities, it is important for urban designers to set up the principles for the setback, form and function of the buildings along the street, thus take optimization control of the spatial form.
随着历史的发展,作为城市空间的重要组成部分的街道空间已成为城市中各类活动发生的场所。城市设计师应基于街道空间在城市中的作用和地位(的考量),来建立沿街建筑的退界原则、形式原则和功能原则,从而(更好地)优化、控制空间形态。
However, in China, the control of the street building forms can mainly meet the basic needs of traffic and safety. The methods and principles for controlling for perception or suitability for activities have hardly been established, especially according to different functions or different locations of the streets. Space syntax, known as a scientific and mature approach, can be used to describing the relationship between street space and the whole or local city configuration.
而在我国,对沿街建筑形态的控制可基本满足交通、安全需求。街道活动的认知分析和适宜性分析的方法和原则至今几乎未确立,特别是对于街道的不同功能或区位(的尺度所进行的分析)。空间句法——作为一种科学且成熟的分析手段,可以用来描述街道空间和城市整体的或在地的组构关系。
Thus this paper takes the calculated value of space syntax as a classification standard, then analyzes the morphological characteristics of street buildings, the distribution of activities alongside the streets of different types. Estimation methods are created and optimization strategy is put forward.
因此,本文以空间句法度量值为分类标准,分析不同类型街道的沿街建筑形态特征和街道活动分布规律。最终,确定评估方法并提出优化策略。
Firstly, street space is classified according to the connectivity value of the road network in Nanjing core urban areas based on space syntax. Then four typical streets are selected as a sample. They are investigated and portrayed in detail with respect to the location, height and function of the buildings alongside them, also including people`s activities on the urban ground floor and so on. Thirdly, the visual perception of street samples (streetscape), the use and distribution of street space, the frequency and density of human activities are evaluated based on existing methods. After comparing the evaluation results of different types and taking the high quality street space as a reference, suggestions are given for further optimization of different kinds of street space. This paper preliminarily demonstrates that it is valid to take the space syntax calculated value as a classification standard when it comes to street spatial morphological optimization.
首先,基于空间句法对南京核心区街道网络中的不同连接度的街道空间进行分类;然后,选取4条具有典型性的街道作为样本,并对其沿街建筑的位置、高度、功能、底层人群活动等进行调研和特征归纳;其后,在现有方法的基础上,对街道的视觉认知(即街景)、街道空间的利用与分布,以及人群活动的频率与密度进行评价;最后,通过比较不同类型街道的评价结果,以得到较好评价结果的街道空间为参考,给出不同类型街道的进一步的优化建议。本文初步论证了空间句法度量值作为街道空间形态优化的分类标准的有效性。
