城市河流滨水空间低碳景观评价指标体系构建研究

Index System and Evaluation Method about Low-Carbon Design of Urban River Waterfront

全球气候变化日益严峻,城市发展过程中各领域的低碳设计逐渐成为未来可持续发展的重要研究方向。本文深入探讨了当前城市河流滨水空间景观设计的现状及存在问题,并针对当前城市河流景观存在的问题及低碳设计相关行业评价标准的不完善性,采用层次分析法等研究方法建立了城市河流滨水空间低碳景观评价指标体系,包含生态健康(B1)、驳岸安全(B2)、低碳技术应用(B3)和可持续发展(B4)4个二级指标以及水质达标率(C1)、岸带植被覆盖度(C2)、生物多样性指数(C3)等16个三级指标,确定了各指标的量化标准与权重,并根据河流低碳景观设计指数为河流滨水空间景观设计方案提供一种量化评价方法。研究结果可在未来对城市河流景观规划建设中有效降低碳排放和提升景观碳汇效能提供理论依据,为践行“双碳”政策和绿色可持续发展理念做出积极贡献。

As global climate change intensifies,low-carbon design across various sectors is emerging as a crucial area of research for sustainable urban development.This paper thoroughly examines the current state and challenges of urban river waterfront landscape design,considering both the existing issues in urban river landscapes and the inadequate evaluation standards for low-carbon design.Employing research methods such as the Analytic Hierarchy Process among others,it establishes a comprehensive low-carbon landscape evaluation index system for urban river waterfront spaces.This system includes four secondary indicators:ecological health(B1),revetment safety(B2),low-carbon technology application(B3),and sustainable development(B4),along with 16 tertiary indicators such as water quality compliance rate(C1),riparian vegetation coverage(C2),and biodiversity index(C3).The study also defines the quantitative standards and weights for each indicator.By offering a quantitative evaluation method based on the Low-Carbon Landscape Design Index(LDI)for riverfront spaces,the research provides a theoretical foundation for effectively reducing carbon emissions and enhancing the efficiency of landscape carbon sinks during planning and construction.These findings significantly contribute to the implementation of policies aimed at"carbon peaking and carbon neutrality goals,"reinforcing the concept of green and sustainable development.
