加快将环渤海地区打造成为中国北方真正增长极,对于构建新时代区域发展格局具有深远意义,以此为立足点解析了 2001-2020年环渤海地区生态-经济-社会(EES)系统耦合协调时空演化特征及驱动机理.结果表明:① EES系统耦合度优于协调度,两者绝对差异及相对差异均呈上升趋势;空间上呈"集聚+级差"的演化格局,形成辽中南城市群、京津唐区、山东沿海城市群 3个相对高值区,耦合协调空间对应关系明显.② EES系统耦合协调空间关联由沿海到内陆呈圈层式热冷点集聚分布;尺度差异格局呈省间差异>省内差异>区间差异.③ EES系统耦合协调空间格局呈核心边缘特征,城市群中心城市为区域增长极;呈等级化特征,与城市行政等级正相关;呈职能化特征,综合型职能城市优于资源型城市;沿海城市优于内陆城市.④ EES系统耦合协调时空格局演化是自然地理区位、子系统相互作用、空间邻近效应、战略政策等诸多要素及相关因子综合驱动的,驱动因子作用方向及区域基本保持一致.
Spatio-temporal evolution characteristics and driving mechanisms of Ecologic-al-Economic-Social system coupling coordination in the Bohai Rim Area
Accelerating the transformation of the Bohai Rim Area into a true growth pole in northern China had profound significance for building a new era of regional development pattern,based on this,this paper sys-tematically analyzed the spatiotemporal evolution characteristics and driving mechanisms of the Ecological-Economic-Social(EES)system coupling coordination in the Bohai Rim Area from 2001 to 2020.The results indicate that:1)The overall development of the coupling degree of the EES system was better than that of co-ordination,and the absolute and relative differences showed a slight upward trend;in terms of space,there was an evolutionary pattern of"agglomeration+differentiation",forming three relatively high value areas:the mid-southern Liaoning urban agglomeration,the Beijing-Tianjin-Tangshan district,and the Shandong coastal urban agglomeration,and the coupling coordination spatial correspondence was obvious.2)The coupling and co-ordination spatial agglomeration characteristics of the EES system were obvious,with a circular distribution of hot and cold spots from coastal to inland areas;the scale pattern showed inter provincial differences>intra pro-vincial differences>interval differences.3)The coupling and coordination spatial differentiation characteristics of the EES system were obvious,showing core edge characteristics,and the central city of the urban agglomer-ation was the regional growth pole;featuring functionalization,comprehensive functional cities were superior to resource-based cities;It had a hierarchical characteristic and was positively correlated with the administrat-ive level of the city;coastal cities develop better than inland cities.4)The coupling and coordinated spatiotem-poral evolution of the EES system was driven by various factors such as natural geographical location,subsys-tem interaction,spatial proximity effect,strategy and policy,and related factors;the direction and region of the driving factors of the two were basically consistent.
