Research On Optimal Design Of Urban Riverfront Landscape Based On "Double Carbon" Target

With the development of global urbanisation and industrial development,global warming,extreme climate disasters and ecological degradation have become problems.In order to mitigate the impact of disasters and promote sustainable development,countries have agreed to a “dual carbon” goal.The origin,construction and development of cities are linked to rivers,which are an important natural resource in modern cities.The urban riverside landscape connects urban rivers to the city and not only carries out the important task of flood control,but also purifies water bodies,maintains the stability of species and satisfies residents’ recreation.As rivers are notoriously flood-prone and poorly accessible,traditional urban riverfront landscape research has focused on both flood safety and vitality enhancement,while its ecological benefits are gradually being emphasised to meet the demands of ecological civilisation,but also mainly in terms of water quality.Urban waterfront landscapes usually run through the whole city and are connected to two carbon reservoirs: forests and wetlands,which are rich in plant resources and have a major impact on carbon neutrality.How to optimise the design of urban waterfront landscapes in the context of the “dual carbon” objective is an urgent issue for consideration.Therefore,this paper attempts to summarise the design methods of urban waterfront landscapes under the "double carbon" target,and apply them to cities that urgently need to sequester carbon and reduce emissions,contributing to the "double carbon" target.Firstly,this paper explains the background,theoretical background and research opportunities of the time,and analyses the concept and development of "double carbon",the related theories,the means to achieve it,and the low carbon analysis to analyse the inner meaning of the "double carbon" target.The mechanism of the link between the"double carbon" objective and landscape gardening,the definition of the scope and specific design elements of urban riverfront landscape,the feasibility,specific methods and necessity of combining the "double carbon" objective with urban riverfront landscape,and finally the construction of "Secondly,this paper analyzes the problems faced by the optimization of urban riverfront landscape based on the "double carbon" objective,compiles the survey and data of urban riverfront landscape,and addresses the issues of weak river continuity,low carbon sequestration,high energy consumption,and high resource efficiency.The five design principles of continuity,high carbon sequestration efficiency,low energy consumption,poor resource utilization and weak functional guidance are proposed,and corresponding design strategies are proposed,including connecting urban river landscape elements,creating high carbon sequestration efficiency plant landscape,optimizing low carbon materials,shaping low energy consumption landscape,optimizing riverfront The paper also proposes five specific strategies,including connecting urban river landscape elements,creating a high carbon sequestration efficiency plant landscape,updating low carbon materials,shaping a low energy consumption landscape,optimising the use of riverfront landscape resources and creating a convenient multi-functional landscape space,to build a composite design method for optimising the urban riverfront landscape based on the "double carbon" objective,and to comprehensively enhance the capacity of the urban riverfront landscape to increase sinks and reduce emissions.Finally,this paper takes the riverfront landscape of the urban section of the Shizi River in Changzhi as the design site,and through the application of the design strategies summarised in the previous paper,constructs an urban riverfront landscape design scheme with high carbon sink,low carbon emission and high guidance.The thesis analyses the influence of "double carbon" on the urban waterfront landscape,and improves the strategy and methodology of carbon neutral landscape in the optimal design of urban waterfront landscape,in order to meet the needs of the times and improve the quality of the environment.
