城市郊野公园作为城镇居住区与自然农林区的过渡地段,对于城市二氧化碳的吸收、通导具有重要作用,其中郊野公园内部绿地结构设计对其碳中和功能发挥起到关键影响.基于郊野公园的碳汇功能发挥,聚焦其绿地边缘空间与内部空间对二氧化碳汇聚、通导、吸收的不同作用,以景观生态学中"廊道、斑块"基本景观要素分别构建"碳捕获区、碳流通区、碳吸收区"3类碳功能区的绿地样方.以CFD流体软件模拟与比较9种典型模式下的风环境与碳环境变化,选择不同碳功能下最优样方模式.以北京市二道绿隔地区郊野公园为例,通过公园绿地结构布局与功能布局,初步探究碳中和视角下郊野公园内部绿地结构布局的构建与应用模式.
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.
