中文摘要:
      规划驱动下的城市化与生态环境耦合关系是区域协调发展的重要问题。针对江淮生态大走廊规划区,采用耦合协调模型和灰色分析方法,探讨了该区域城市化与生态环境的耦合特征及影响因素。结果表明:2012-2016年间,城市化与生态环境指数均为线性增加过程,且增幅较大。不同地区城市化指数变化过程较相似,同步性较好,但生态环境指数存在一定差异;城市化与生态环境耦合关系在区域上可划分为两类,其一为波动型耦合关系,包括淮安、宿迁和徐州3市,其二为平稳型耦合关系,包括扬州、泰州两市;江淮生态大走廊整体城市化与生态环境的耦合度与协调度都呈线性增加过程,除2013年外,其余年份都为高水平耦合阶段。2012和2013年为中、低协调发段,2014-2016年为高协调或极协调阶段;空间城市化、社会城市化和人口城市化方面的结构性指标是影响耦合关系的主要城市化因素,而水气环境是影响耦合关系高低的主要生态环境因素。
英文摘要:
      The coupling interaction and coordination between urbanization and ecological environment is a key issue for harmonious development in regional planning strategy. This paper uses the coupling interaction and coordination degree model and Grey Relevance Analysis to explore the evolution of urbanization and ecological environment and its influencing factors in the ecological corridor of Yangtze-Huai River (ECYHR). The results showed that: the urbanization and the ecological environment indices generally increased linearly between 2012 and 2016 with a relatively large amplitude. The urbanization indices between different cities had similar trend, but with different ecological environment indices. The five cities in the ECYHR can be divided into two types, one is characterize as fluctuation coupling relationship, which consists of Huaian, Suqian and Xuzhou; the other is featured to be stable coupling relationship, which consists of Yangzhou and Taizhou. The coupling degree between urbanization and ecological environment is in high coupling stage in studied five years except for 2013. The year of 2012 and 2013 are in the low-to-middle coupling coordination stage, and it changed into high coupling coordination stage ever from 2014 to 2016. The indices relevant to spatial, social and the demographic urbanization has larger weight in the factors of the urban system, and the indices relevant to the water and the atmospheric environments has larger weight in consideration of the factors in the aspect of the ecological environment system.
