Abstract

This paper presents an analysis of the employment and residential functions of Xi'an City People's Stadium and the factors influencing ambient fine particle (PM_2.5) concentrations. The spatial distribution of employment and home locations in Xi'an extends to the surrounding in the form of “employment-mixed-residential-mixed”. Based on this result, the PM_2.5 concentration data, environmental factors, traffic flow data, and the jobs-housing imbalance factor are selected to fit the PM_2.5 concentration of the City People's Stadium, with an adjusted R² of 0.97. The dissipative structure theory is used to analyze the PM_2.5 at the City People's Stadium, identifying the factors leading to a threshold exceedance for PM_2.5. This study tests a 20 % reduction in traffic flow in Xi'an to verify the model's effectiveness at detecting threshold exceedance.

工作-住房平衡对社区交通和空气质量的影响

本文对西安市人民体育场的就业、居住功能及环境细颗粒物（PM2.5）浓度的影响因素进行了分析。西安就业和居住区位的空间分布以“就业-混合-居住-混合”的形式向周边延伸。在此基础上，选取PM2.5浓度数据、环境因素、交通流量数据和职住失衡因素对城市人民体育场PM2.5浓度进行拟合，调整后R2为0.97。运用耗散结构理论对城市人民体育场的PM2.5进行分析，找出导致PM2.5阈值超标的因素。本研究以西安交通流量减少20%为例，验证了该模型在检测阈值超标方面的有效性。
