摘要
城市道路网是城市空间结构的骨架,是连接城市各功能区的纽带。路网结构的完善是城市可持续发展的重要保证。本文以中国西部12个省会城市、直辖市为研究对象,运用空间句法评价方法对中国西部城市建成区路网进行量化处理和描述,并辅以SPSS软件对可达性进行相关性分析。从全局可达性、局部可达性、感知可达性3个方面对研究区域范围内的路网进行可达性测度,并对路网进行评判优化。研究结果表明:(1)西部城市可达性与城市规模和形态呈一定程度的正相关。西部城市因为受到地理、历史条件的影响较大,所以西部城市的路网呈现不均衡式的发展,甚至有些边陲地区的路网总体上处于一种无序的低效发展状态。(2)西部城市的全局可达性、局部可达性、感知可达性总体呈中等偏下水平。因此,本文旨在提高西部城市交通可达性而对路网结构进行优化分析,为西部城市的规划决策提供建设性的建议。
The urban road network is the skeleton of the urban spatial structure and the link between the spatial links between the functional areas.The improvement of the road network structure is an important guarantee for the sustainable development of the city.This paper takes 12 provincial capital cities and municipalities directly under the central government in western China as the research object,and uses the spatial syntax evaluation method to quantify and describe the road network of urban built-up areas in western China.And the SPSS software is used to analyze the correlation of accessibility.From the aspects of global reachability,local reachability and perceptual reachability,the reachability measurement of the road network within the research area is carried out,and the road network is judged and optimized.The results show that:(1)The accessibility of western cities is positively correlated with the size and shape of cities.The road network of western cities is unevenly developed,and it is greatly affected by geographical and historical conditions.The road network of some border areas is generally in a state of disorderly and inefficient development.(2)The overall accessibility,local accessibility,and perceived accessibility of western cities are generally moderately lower.Therefore,this paper aims to improve the accessibility of western cities and optimize the structure of road networks to provide constructive suggestions for planning decisions in western cities.
