基于空间内外耦合的广州碧道建设初探

Construction of Guangzhou Ecological Belt Based on Spatial Internal and External Coupling

摘要:

碧道是集多功能于一体的滨水复合型廊道，碧道建设不仅是陆域和水域的共建，更是空间内外耦合营造的典型范例。通过对空间内外耦合模式进行梳理，明晰碧道建设的空间耦合关系。从广州碧道生态空间与人文空间内外耦合层面出发，归纳得出 3 种耦合手法，探讨其构成要素与耦合机制：1）打造水生态带，将水环境、水生态、水景观与水游憩视为有机整体；2）构建“生态 - 人文”防洪堤，提升防洪堤的多功能性；3）打造“防洪 - 通航”景观闸桥，实现交通、景观与防洪需求。分析得到目前仍存在建设缺乏整体性与系统性、多元融合培育不充分的不足，并提出挖掘水经济、丰富“碧道 +”模式等建议。

Abstract:

Ecological belt is a multifunctional waterfront complex corridor, and the construction of anEcological belt is not only the co-construction of land Ecological belt is a multifunctional waterfront complex corridor, and the construction of Ecological belt is not only the co-construction of land and water, but also a typical example of spatial internal and external coupling. The spatial coupling relationship of Ecological belt construction is clarified by sorting out the spatial internal and external coupling modes. Three coupling methods are summarised based on the internal and external coupling of ecological space and humanistic space of the ecological belt in Guangzhou. Their components and coupling mechanisms are explored: 1) to create a water ecological belt and to consider the water environment, water ecology, water landscape and water recreation as an organic whole; 2) to build an 'ecological-humanistic' levee and to enhance the multi-functionality of the levee; 3) to build a 'flood control-navigation' landscape gate and bridge to achieve the traffic, landscape and flood control needs. It analyses the lack of holistic and systematic construction and insufficient cultivation of diversified integration. It suggests exploring the water economy and enriching the mode of 'Ecological belt +'.
