Study on the Green Space Structure of Urban Country Parks Based on Wind and Carbon Environment Simulation from the Perspective of Carbon Neutrality
As the transition section between urban residential areas and natural agricultural areas,urban country parks play an important role in the absorption and transmission of urban carbon dioxide.The design of the internal green space structure of the country park plays a key role in its carbon neutralization function.Based on the exertion of the carbon sink function of the country park,this study focuses on the different effects of its green space edge space and internal space on the carbon dioxide accumulation,transmission and absorption.The study constructs green space samples of three types called"carbon capture area,carbon circulation area,and carbon absorption area"based on the basic landscape elements of"corridors and patches"in landscape ecology.CFD fluid simulation software is used to simulate and compare the changes of wind environment and carbon environment under 9 typical modes,and the optimal quadrat mode under different carbon functions is selected.With the second green belt of Beijing as an example,the coupling application relationship between the form of"corridors and patches"in the sample area and the park landscape elements is analyzed,and the construction approach of the internal green space structure layout of the country park under the guidance of carbon sink is preliminarily explored.
