基于CO<sub>2</sub>扩散模拟的校园空间低碳优化研究

Abstract

在保持绿地面积总量的前提下提高植物固碳能力，并以此提出优化校园绿地空间的布局模式。本文以沈阳建筑大学校园为依托，开展了基于绿地固碳功能与CO2空间分布相耦合的城市绿地空间布局研究，通过CFD模拟技术获取校园CO2空间分布格局，利用CO2空间数据耦合绿地固碳功能，揭示植物固碳效应最佳边界。最终提出了校园绿地空间布局模式，优化了校园绿地空间布局，使校园绿地在有限的面积下发挥了最大的生态效应。研究结果为城市以及更大范围内的绿地空间布局模式的选择, 应对全球气候变化和温室气体减排，以及提升城市空间环境质量方面具有重要意义。 On the premise of keeping total green areas to improve plant carbon sequestration ability, the model of optimizing the layout of the campus green space was put forward. This article focused on Shenyang Architecture University campus, and discussed urban green space layout based on the relationship between the green carbon sequestration function and CO₂ spatial distribution. At the same time, we obtained CO₂ space distribution pattern through CFD simulation technology, and revealed that plant carbon sequestration effect was the best boundary by using of CO₂ space data with green carbon sequestration function. The paper raised the mode of campus green space layout, optimized the campus green space layout, and made the campus green space in the limited area under playing the biggest ecological effect. The result is of great significance for the city, a broader range of green space layout pattern choice, response to global climate change and greenhouse gas emissions, and promotion of the urban space environment quality.
