摘要:城镇化快速发展既推动了国家经济增长，又产生了严重的生态环境问题。随着集聚经济不断发展，城镇化形态逐渐由单中心向多中心空间格局（包括极化和扁平式两种类型）演变。而关于两种多中心模式下城镇化与生态环境协调发展关系研究仍然缺乏。以福州大都市区（极化式）和厦漳泉大都市区（扁平式）为研究案例，分析2011-2017年两种多中心城镇化模式对城镇化与生态环境耦合协调发展的影响。结果表明：（1）两种多中心空间格局均有利于区域城镇化水平、生态环境水平以及城镇化与生态环境耦合协调度的提高；（2）除生态环境外，极化式与扁平式多中心格局对城镇化水平、城镇化与生态环境耦合协调发展均具有均衡效应；（3）福建两大都市区城镇化水平相对滞后，不利于城镇化与生态环境协同发展。本研究对于优化福建省城镇化空间布局，提高城镇化可持续发展水平具有重要意义。



Abstract:Chinese rapid urbanization has promoted its economic growth, while brought serious ecological environment problems simultaneously. Accompanying the development of agglomeration, the region urbanization form has gradually transformed from monocentric structures to polycentric structures which can be divided into two kinds of spatial structure:concentrated and dispersed polycentric structures. However, there still lack the research of the relationship between urbanization and ecological environment of the two forms of polycentric structure. This study focuses on two metropolitan areas in Fujian Province from 2011 to 2017 that Fuzhou metropolitan is defined as concentrated polycentric region and Xia-Zhang-Quan metropolitan is defined as dispersed polycentric region. The results suggested that:(1) Both of the two metropolitan areas are conducive to the improvement of regional urbanization, ecological environment and the coupling and coordinated development between urbanization and ecological environment (CCDUEE). (2) There's a convergence of urbanization development and CCDUEE in both two polycentric areas, except the ecological environment. (3) The lagging urbanization of the two metropolitan areas against the coordinated development between urbanization and ecological environment. The study provides significant references for optimizing the spatial structure and improving sustainable urbanization level in Fujian.
