城市用地格局对居民出行影响研究

城市用地格局对居民出行有着决定性的影响.我国城市的发展实践表明,不同发展阶段形成的不同特征的用地格局往往导致完全迥异的居民出行特征,现阶段各大城市蔓延形成的无序且低密度的用地模式通常不利于居民出行良性结构的形成.借鉴景观生态学中的空间格局分析方法,引入多样性、优势度、均匀度、破碎度等指数对城市用地空间格局进行定量描述,在此基础上研究了苏州市城区用地格局演变对居民出行特征的影响,指出用地格局不合理是导致居民出行条件恶化的主要因素.

Analyzing Impacts of Land-Use Patterns on Travel Characteristics

Land use patterns are one of the critical influencing factors to urban travel characteristics. It was observed in China that different land use patterns formed in different land use development periods led to totally different travel characteristics. The current land use patterns in metropolitan areas are sprawling un-orderly with scattered parcels isolated from each other, resulting in unfavorable daily travel conditions to trip-makers in those areas. Through introducing landscape-ecological spacing methods, this paper analyzes in a quantitative manner the land use patterns in Suzhou, Jiangsu Province, based on measures of diversity, superiority, evenness, and fragmentation. The results show that the evolution of the land use patterns in the city influences travel characteristics, and the unreasonable land use patterns are the main factors that cause problematic travel characteristics.
