摘　　要：协调生态网络格局与城镇网络格局是实现城市群区域可持续发展的重要课题。湾区城市群因其独特的地理优势和经济活力成为区域发展的核心单元,但其生态与城镇发展的协同问题日益凸显。以粤港澳大湾区城市群为例,通过综合运用形态空间格局分析、景观格局指数、最小累积阻力模型等方法确定生态源地和经济社会源地,识别生态廊道和交通廊道,构建湾区城市群区域的生态与城镇双网络格局,探讨双网络格局空间关系与干扰情况,最后提出湾区城市群跨区域生态协同的建议。结果表明:(1)提取生态源地30个,总面积21205.0 km^(2),经济社会源地422个,总面积7629.35 km^(2),生态廊道、交通廊道总面积分别为8506.98 km^(2)和4562.11 km^(2),共同构成了外环形生态屏障和城镇发展内循环网络;(2)生态关键点1011个、生态干扰点7527个,对其进行针对性修复和保护可显著改善生态连通性;(3)识别研究区具有源地协同、流域协同和滨海协同等三种生态协同类型,并提出了构建城市群跨区域生态协同模式框架。Coordinating ecological network patterns with the urban network patterns is crucial for sustainable development in urban agglomerations.The bay area urban agglomerations,with their unique geographical advantages and economic vitality,have become the core unit of regional development,but the synergy between ecological and urban development is increasingly critical.Taking the Guangdong⁃Hong Kong⁃Macao Greater Bay Area as an example,by comprehensively applying methods such as morphological spatial pattern analysis,landscape pattern indices,and the least cumulative resistance model to determine ecological sources and economic and social sources,identify ecological corridors and traffic corridors,construct the ecological and urban dual network pattern of the bay area urban agglomeration region,explore the spatial relationship and interference of the dual network pattern,and finally propose suggestions for cross⁃regional ecological synergy in the bay area urban agglomeration.The results showed that(1)The study area contains 30 ecological sources spanning 21205.0 km^(2)and 422 socioeconomic sources spanning 7629.35 km^(2)..The total area of ecological and transportation corridors are 8506.98 km^(2)and 4562.11 km^(2)respectively,together forming an outer ring⁃shaped ecological barrier and an internal cyclical network for urban development around the study area.(2)The study area features 1011 key ecologicalpoints and 7527 ecological disturbance points,offering opportunities for targeted restoration and protection to enhanceecological connectivity significantly.(3)Three types of ecological synergy in the study area were identified based onsource,watershed and coastal wetland.A framework for constructing a cross⁃regional ecological synergy model for urbanagglomerations was proposed.
