摘　　要：【目的】识别都市圈的核心区和边缘区是分析都市圈发展问题的关键。耦合空间环境和人类社会活动两个层面,刻画都市圈“核心-边缘”空间结构特征,从而深化对于都市圈动态演化机制的理解,进一步揭示都市圈内部差异化的成长模式及其对周边区域的辐射效应,对于未来优化都市圈的空间资源配置具有重要意义。【方法】以广州都市圈和深圳都市圈为研究区域,基于土地利用数据、遥感影像等多源数据,采用耦合协调度模型等分析方法,通过测度物理环境与社会活动的耦合协调度识别两大都市圈的核心区和边缘区,并对都市圈边缘区域进行分类分析。【结果】(1)2010—2020年广州都市圈和深圳都市圈的良好及优质协调区面积快速增长,优质协调区在城市中心集聚成片,良好协调区由中心向外围扩张。(2)广州都市圈核心区呈现“核心集聚型”的核心区空间形态,空间扩张模式以边界填充为主,空间格局相对稳定;深圳都市圈核心区呈现“带状连绵型”核心区空间形态,以走廊式特征快速扩张,扩张区域主要集中在深圳市东北部及东莞市中部和东部。(3)将都市圈边缘区划分为近郊居住型、工业与物流园型、农业与生态保护型、新兴发展型、过渡性混合型5种空间类型。其中,广州都市圈主核心区东北侧边缘区多为农业生态保护型;西南侧多为过渡性混合型。深圳都市圈边缘区类型和分布模式复杂,东莞和深圳片区已基本被主核心区覆盖,深惠交界处多分布近郊居住区型边缘区。【结论】基于“核心-边缘”的空间分析视角,对都市圈的空间结构特征进行刻画,能较为准确地反映都市圈的空间发展状况与演化趋势。都市圈核心区和边缘区的空间形态差异明显,强化“核心-边缘”联系、优化边缘区域组团定位与分工、实施差异化的发展策略是推动都市圈“核心-边缘[Objective]Identifying the core and peripheral areas of a metropolitan region is crucial for analyzing its development issues.Characterizing the core-periphery spatial structure of a metro‐politan region by coupling the spatial environment and human social activities is of great signifi‐cance for optimizing the spatial resource allocation of the metropolitan region.[Methods]Focusing on the Guangzhou Metropolitan Region and Shenzhen Metropolitan Region,this study uses multi-source data(land-use data,remote sensing images)and methods like the coupling coordination degree model to identify primary and secondary core area and classify the latter.[Results](1)From 2010 to 2020,high-quality coordinated areas in both regions increased rapidly,clustering in city centers with well-coordinated areas expanding from center to periphery.(2)The Guangzhou Metropolitan Region’s core area expanded mainly through near-boundary filling,maintaining a relatively stable spatial pattern.In contrast,Shenzhen’s core area expanded corridor-like towards the northeast of Shenzhen City and central-eastern Dongguan City,forming a strip-continuous spatial form.(3)Peripheral areas were classified into four types:suburban residential,industrial and logistics park,agricultural and ecological protection,emerging development,transitional mixed.In Guangzhou,the northeastern side of the primary core area was mostly agricultural/ecological,while the southwestern side was transitional mixed.Shenzhen’s peripheral areas are complex,primarily distributed in Huizhou City.[Conclusion]Core and peripheral areas’spatial forms differ significantly.Strengthening core-periphery connections,optimizing peripheral area positioning and labor division,and implementing differentiated strategies are effective ways to promote coordinated development.
