The Evaluating Low-carbon Ecology of Coastal Cities and a Construction Path Based on Nature-based Solutions

Abstract

Due to the natural and social features of the coastal zone, coastal cities are facing more contradictions and difficulties between ecological protection and urban development. And the goal of carbon peaking and carbon neutrality puts forward new requirements for the high-quality development of coastal cities. The paper suggests that Nature-based Solutions (NbS) has guiding significance in exploring the way to construct low-carbon ecology in coastal cities, and attempts to discuss the practical application of NbS in the urban dimension. Through case study of Zhoushan, a coastal city, this paper uses modeling and measuring to evaluate the low-carbon ecology of target cities.Based on the results of evaluation, this paper further attempts to build a propagable development path of low-carbon ecology in coastal cities under the guidance of NbS thinking and practice, including following the goal orientation to complete social challenges; adhere to the system view under the time scale and space scale; actively build models or standards for technical support, comprehensive management, economic feasibility and cultural embellishment; cultivate diversified stakeholders.
