基于空间句法的城镇路网规划研究--以灵璧县黄湾镇为例

Research on town road network planning based on space syntax:A case study of Huangwan Town,Lingbi County

小城镇的道路与功能布局之间的矛盾日益显著,现状道路网规划更多地以距离与时间来衡量道路的合理性与可达性,较少考虑到道路空间的相对位置即几何属性与其拓扑关系。运用空间句法量化方法,通过“量化分析—方案构建—比较择优”的技术路线,编制安徽省灵璧县黄湾镇路网规划,以期为城镇路网规划提供定量研究新思路。研究分析了黄湾镇区路网的现状特征、存在问题及发展趋势,并与实地观察、问卷调查的结论互为补充与印证。基于发展需要与限制条件,在现状基础上构建了向西和向北发展的两种路网方案。进而比较两种方案的各项空间指标,得出更适合镇区发展的道路网络系统。

At present,the contradiction between the road network of small towns and the functional layout of townships is increasingly obvious.In the road network planning of small towns,the rationality and accessibility of roads are measured more by distance and time,and the relative position of road space,namely,the geometric attribute and its topological relation,is rarely considered.This paper uses the quantitative method of space syntax,through the technical route of"quantitative analysis,scheme construction,comparative selection",formulates the road network planning of Huangwan Town,Lingbi County,Anhui Province,in order to provide a new way of quantitative research for urban road network planning.This paper analyzes the current characteristics,problems and development trend of road network in Huangwan Town,and complements and verifies the conclusions of field observation and questionnaire survey.Based on the development demands and constraints,two road network schemes are constructed to develop westward and northward.Then the spatial indexes of the two schemes are compared to get the road network system more suitable for the development of township.
