Based On CO₂ Diffusion Simulation Study On The Layout Optimization Of Green Spaces In Shenyang North New Area

With the rapid development of carbon dioxide emissions of the city's rapid increase prompted the rapid rise in the total amount of greenhouse gases in the world,the city greenbelt system plays a very active role in reducing global greenhouse gas emission in response to climate warming.The traditional research methods that increase the amount of carbon sink decrease the content of greenhouse gas is mainly through total quality green green area increase or increase carbon sequestration,but in the case of the green area can not be unlimited supply of green space.How to improve the green carbon sequestration capacity has become an important problem to study this down in the existing green area.The results show that the constant Higher concentrations of carbon dioxide can enhance plant carbon sequestration,carbon dioxide and air pollutants are closely related to the spatial distribution of spatial pattern,so we can simulate the spatial distribution of carbon dioxide to guide the implementation of green space,green space layout and ecological effects of vegetation are coupled to play the best ecological benefit,which not only can fully exert the effect of plant carbon sequestration also,can reduce the content of other air pollution gases in the atmosphere,so as to improve the air quality.City greenbelt area is limited,we can not blindly increase the green area to increase the amount of carbon sink,so with the green space layout optimization case study of Shenyang North New Area,to carry out the research on green space layout of green carbon sequestration and pollutant abatement effect based on coupling,elaborated how in the limited area of green space next,the spatial distribution pattern of carbon dioxide through the simulation technology to obtain the city atmospheric dynamics,reveal the spatial distribution characteristics of carbon dioxide,the definition of City plant ecological effect best boundary,spatial layout optimization of city green space system,increase the amount of carbon sink from the spatial pattern change,resulting in the limited city green area Under the play to maximize the ecological effects of vegetation,in order to increase the amount of carbon sequestration to reduce the concentration of carbon dioxide in the city,alleviate the greenhouse effect.This research can provide methods and technical support for Shenyang city and other industrial city green space system ecological planning and construction for reference.This paper is divided into six chapters,the first chapter through to the world,China and Shenyang North New Area three levels of carbon emissions situation and research summary,put forward to study the problem,determine the purpose and significance of research and research content,using the method and technical route,laid the foundation for the next step will be the research.The second chapter summarizes the related concepts used in this study,the theory and methods,to be used according to the concrete conditions of Shenyang North New Area in the next section,in-depth analysis and summary.The third chapter on Shenyang North New Area related introduction of the carbon source and sink calculation shows that Shenyang North New Area current carbon emissions to far The super carbon amount.In the fourth chapter,from the large scale domain,three point scale in built-up area and small scale residential area to spread the application of geographic information system technology and CFD software of carbon dioxide is simulated,the simulation results obtained Shenyang North New Area carbon dioxide,and analyzed the simulation results obtained in different scale space integration.Under the condition of the land suitability distribution results,after the contrast verification proves the feasibility of the method was by the methods of field testing of the simulation results.The fifth chapter is based on the simulation results respectively from the macro,meso and micro three aspects of Shenyang North New Area's green space layout optimization is put forward corresponding strategies.The results of this paper are summarized,and the problems and deficiencies in the research process are pointed out.Finally,the future development of green space optimization and layout system is prospected.
