以浙江省69个县(市)为研究对象,利用1996、2004、2012年交通路网和经济社会数据,采用加权平均旅行时间指标、主成分分析法和耦合协调度模型,探讨城市综合交通可达性时空演变及其与经济社会耦合协调发展关系。研究结果表明:(1)1996~2012年,城市综合交通可达性以及经济社会发展水平均出现不同程度提高,两者耦合协调关系逐渐由低水平向高水平转变;(2)协调性存在空间分异,环杭州湾、金丽衢平原、温台平原城市协调性普遍高于西部低山丘陵地区城市,地级市辖区协调性普遍高于各县(县级市);(3)协调性空间格局演变显著,呈现出由东北向西南、中心城市向周围县域梯度改善现象,且逐等级类型提升特征显著。总体上来看,浙江省城市可达性演变及与经济社会的耦合协调关系,体现了区域经济社会发展以及交通基础设施完善的结果。
Taking 69 counties (cities) in Zhejiang Province as the research object and using the traffic network and economic and social data in 1996, 2004 and 2012, the weighted average travel time index, principal component analysis and the coupling coordination model were used to explore the feasibility of urban comprehensive traffic Evolutionary Spatial - Temporal Evolution and Its Relationship with Economic and Social Coupling and Coordinated Development. The results show that: (1) From 1996 to 2012, the accessibility of urban comprehensive traffic and the level of economic and social development all increased to some extent, and the coupling and coordination relationship gradually changed from low level to high level; (2) There was room for coordination Differentiation, Central Hangzhou Bay, Jinliqu plain, Wentai Plain, the urban coordination is generally higher than in the western hilly region, prefecture-level city area generally higher than the county (county-level cities); (3) Coordination of spatial pattern Evidently evolving. It shows a gradual improvement of the gradient from northeast to southwest and central cities to the surrounding counties, and is characterized by a significant increase in graduation type. Generally speaking, the evolution of urban accessibility and the coupling and coordination with the economy and society in Zhejiang Province reflect the result of regional economic and social development and improvement of transportation infrastructure.
