Identifying and revealing the coupling relationship between urbanization and ecological environment and its forming mechanism, and then putting forward regulation measures, will benefit urban management in making decisions. We examined the coupling process between new-style urbanization and ecological environment system of Fujian Province through the coupling model and coupling-coordination model, and realized the spatial visualization based on the index system of urbanization and ecological environment, in which the index weight was based on the variation coefficient. The results showed that the variation of coupling degree between new-type urbanization and ecological environment system was relatively stable, ranging from 0.77 to 0.99 during 2000 to 2015. There was no obvious difference among the cities except for the Putian in 2000 and Zhangzhou in 2010 were in the break-in stage. The coupling-coordination degree between new-type urbanization and ecological environment system fluctuated around 0.50 during 2000 to 2015 with significant spatial differentiation and shorter evolution time from east to west. The coupling-coordination types of Fujian Province were dominated by the harmonious development type, accompanied by the types of moderate unadjusted recession, moderate coordinated development, and high coordinated development. There was transformation phenomenon among different types. Xiamen was the only one deve-loped into the high coordinated development type in 2015. The city development was mainly featured by lagged urbanization, with the lagged ecological environment in Xiamen in 2010 and in both Fuzhou and Xiamen in 2015.
识别和揭示城镇化与生态环境之间的耦合关系及其形成机理,进而针对性地提出调控对策,有助于城市管理相关部门制定决策.本研究针对福建省所处立地环境构建新型城镇化与生态环境系统指标体系,利用变异系数确定指标权重,通过耦合度模型和耦合协调度模型探讨福建省新型城镇化与生态环境系统的耦合过程,并实现空间可视化.结果表明: 2000—2015年,福建省地级市的新型城镇化与生态环境系统耦合度变化相对平稳,其值在0.77～0.99,且各城市间差异不显著,只有2000年莆田和2015年漳州的耦合度处于磨合阶段;福建省新型城镇化与生态环境系统耦合协调度在0.50上下波动,从东向西演变时间短,空间分异显著;福建省两系统耦合协调类型以调和发展型为主,还存在中度失调衰退型、中度协调发展型和高度协调发展型,两系统耦合协调类型间还存在转化现象,到2015年只有厦门发展为高度协调发展型城市;城市发展以城镇化滞后为主,到2010年(厦门)和2015年(厦门和福州)才出现生态环境滞后现象.
