摘要
依托湾区特定的地理区位与港口交通优势,海湾型都市圈已成为国际竞争和低碳转型发展的重要空间单元.基于"绿色低碳、产业辐射和科创集群"3 种海湾型都市圈规划模式的比较,文章重点解析了契合当前"双碳"建设目标的绿色低碳模式.基于对"翡翠之城"西雅图都市圈的案例解析,揭示了低碳规划模式以"织补绿色生态网络、链接绿色区域格局、优化绿色产业体系"3 个方面为核心,从"碳汇增量、碳汇提质、低碳布局、低碳交通、低碳设施、产业类型、产业结构、绿色市场"8 个方面,构成了海湾型都市圈绿色低碳规划发展的前沿探索.结合我国双碳发展目标和海湾型都市圈现实,进一步从"生境(绿色织补)、城境(空间承载)、产境(市场激活)"3 个维度提出了我国海湾型都市圈绿色低碳发展路径.他山之石可为我国低碳可持续都市圈发展探索提供启示与借鉴.
Abstract
Relying on the unique geographic location and port transportation advantages of bay areas,bay-type urban agglomerations have become important spatial units for international competition and low-carbon transformation.Based on a comparison of three planning models for bay-type urban agglomerations—"green and low-carbon,industrial radiation,and sci-tech innovation clusters"—this article focuses on analyzing the green and low-carbon model that aligns with the current"dual-carbon"goals.Through a case study of the"Emerald City"Seattle metropolitan area,the article reveals that the low-carbon planning model centers on"weaving green ecological networks,connecting green regional patterns,and optimizing green industrial systems".It identifies eight key aspects of green and low-carbon planning development for bay-type urban agglomerations:carbon sink enhancement,carbon sink quality improvement,low-carbon spatial layout,low-carbon transportation,low-carbon facilities,industry types,industrial structures,and green markets.In light of China's dual-carbon development goals and the realities of bay-type urban agglomerations,the article proposes a green and low-carbon development path for China's bay-type urban agglomerations from three dimensions:habitat(green restoration),urban framework(spatial carrying capacity),and industrial framework(market activation).The experiences of other countries offer valuable insights and lessons for exploring sustainable and low-carbon development in China's urban agglomerations.
