Research On The Optimization Of Microclimate Environment In The Street Space Of Beijing Old City Area Under The Concept Of Low Carbon

Today,climate change has become one of the major challenges recognized globally.In order to adapt to and improve climate change and control greenhouse gas emissions,how to achieve long-term development in street space with the concept of low-carbon is considered to be an important practice to form a systematic urban renewal.Therefore,in the cross research of low-carbon construction and microclimate spatial environment,we aim to find a refined transformation model of urban street space under the low-carbon concept,and provide strategies for future urban renewal to build a more comfortable street spatial environment.Based on the concept of low carbon,this paper combines the microclimate environment of the street space in the old city of Beijing with low carbon comprehensive benefits,and constructs the renewal path and design strategy of the street space in the old city of Beijing from macro to micro dimensions.By exploring the impact of low carbon city construction on the microclimate environment elements of street space,we can further enrich the existing achievements of low carbon city construction,and provide some reference for the optimization of the microclimate environment of streets in the old urban areas of Beijing.Firstly,conduct an overall environmental analysis of the block units in the old urban area of Beijing at a macro scale,construct an evaluation system for climate environment and carbon sink service functions,and conduct a macro level evaluation of administrative division street units at the block scale.Secondly,through the evaluation system,Xinjiekou Street(2.3688)with lower scores was selected as a typical street for key research.Quantitative analysis of the mesoscale low-carbon comprehensive benefit value of the street was conducted,and a street plant information database was established.The total annual ecological benefit value of the8 roads surveyed was 13.57711 million yuan,with an average comprehensive ecological benefit value of 4188.01 yuan per plant.Calculate the comprehensive benefit value evaluation results of each road in the street,rank the low-carbon benefit value of the road,and obtain the SS8 street with the lowest benefit value.Once again,simulate the microclimate environment of street space at a micro scale,and analyze the influencing factors of street space microclimate from a dual perspective of low-carbon and people-oriented.Finally,guided by the above conclusions,a strategy for optimizing the overall street environment in the old urban area of Beijing is proposed,and a detailed method for optimizing the node environment is proposed by summarizing the specific problems of typical street spaces.Finally,strategic guidance is proposed for optimizing the microclimate environmental factors under the low-carbon concept.The purpose of this paper is to study the construction of a street space system shared by the whole people under the concept of low carbon in the old urban area of Beijing,and to conduct classified guidance and refined management based on the exploration of road shape and classification.Effective conclusions are drawn on carbon sink monitoring,ecological efficiency enhancement and optimization of microclimate environmental factors,and finally the improvement and promotion strategy of street space climate environment is proposed.Put forward the idea of low carbon and sustainable development of street space design,which will provide reference and practical significance for the realization of the “carbon peaking and carbon neutrality” goal in the future.
