基于韧性理念的小城镇道路系统更新设计的方法与实践

The Method and Practice of Small Town Road System Renewal Design based on the Concept of Resilience

文章以新昌县儒岙镇为例,从韧性理念的视角切入,探讨了小城镇道路系统更新设计的方法与策略。研究采用空间句法与实地调研分析相结合的方法,研究表明:(1)儒岙镇路网密度较低,镇区道路韧性相对较差。(2)特殊路段存在人车流量骤增导致的交通拥堵现象,不利于可持续发展。基于问题导向,进而提出小城镇道路系统可持续更新的策略:(1)优化道路系统网络,根据空间句法识别的现状问题进行路网优化并进行验证。(2)优化道路弹性设计,从景观、建设、管理三个维度提出道路“弹性空间”营造的策略与方法。

Taking Ru'ao Town of Xinchang County as an example,this paper discusses the methods and strategies of the road system renewal design in small towns from the perspective of resilience concept.The research adopts the method of Space Syntax and field investigation analysis.The results show that:(1)The road network density in Ru'ao town is low,and the toughness of the road in the town is relatively poor.(2)Traffic congestion caused by sudden increase of traffic flow in special sections is not conducive to sustainable development.Based on the problem orientation,the sustainable renewal strategy of the road system in small towns is proposed:(1)Optimize the road system network,optimize the road network according to the current problems of space syntax recognition and verify it.(2)Optimize the design of road elasticity,and propose the strategies and methods for creating road"elastic space"from three dimensions of landscape,construction and management.
