江苏省高速交通与旅游耦合协调发展时空演化研究

Research on the Spatiotemporal Evolution of Coupling and Coordinated Development of High-Speed Transportation and Tourism in Jiangsu Province

以江苏省13个设区市为研究对象,以2000年、2009年、2018年为时间断面,构建了高速交通优势度和旅游业发展水平评价体系,在此基础上运用耦合协调模型分析了高速交通系统与旅游系统耦合协调发展的时空特征。结果表明:全省高速交通优势度稳步提升,苏南地区以南京为核心、沿沪宁线逐步形成了高速交通优势带,苏中和苏北地区高速公路网尚显不足,高铁建设严重滞后;全省旅游业发展水平南强北弱的空间格局变化不大;全省高速交通系统与旅游系统的耦合协调水平逐渐提升,从重度失调转变为初步协调,但耦合协调度总体仍不高,空间分布上自南向北递减;全省高速交通发展水平相对高于旅游业发展水平,省内大多数城市为旅游滞后型。

Taking 13 cities with districts in Jiangsu province as the research object and 2000,2009,2018 as the time section,this paper constructs the evaluation system of high-speed transportation superiority and tourism development level.On this basis,the coupling coordination model is used to analyze the spatiotemporal characteristics of the coupling and coordinated development of high-speed transportation system and tourism system.The results show that the high-speed transportation superiority in the whole province has steadily improved.With Nanjing as the core,southern Jiangsu has gradually formed a highspeed transportation superiority belt along the Shanghai-Nanjing line.In central and northern Jiangsu,the expressway network is still insufficient,and the construction of high-speed railway is seriously lagging behind.The spatial pattern of tourism development level in the whole province is strong in the south and weak in the north.The coupling coordination level between high-speed transportation system and tourism system in the whole province has gradually increased,from severe imbalance to preliminary coordination.However,the overall coupling coordination degree is still not high,and the spatial distribution decreases from south to north.The development level of high-speed transportation in the whole province is relatively higher than that of tourism,and most of the cities in the province are lagging behind in tourism.
