| 摘 要： | 以复杂网络理论为基础,运用最短增广链算法构建城市PM2.5扩散的容量网络模型。通过分析城市环境中水平距离、海拔、风力等因素的作用,对PM2.5区域性扩散的物理过程进行一次有益的探索。西安市近期空气监测数据的实证分析显示,预测值与监测值基本吻合。同时,模型输出揭示了西安市PM2.5的扩散途径。

| Abstract: | Build the capacity network diffusion model of PM2.5 in urban areas with the algorithm of the shortest augmenting chain based on the theory of complex network. By analyzing the influence of various factors including horizontal distance, altitude and wind power, explore the physical transfer process of PM2.5 in urban areas. Following instance analysis with Xi'an air quality data showed that predicting values and actual measured values were generally consistent. Meanwhile the output of model reveals the diffusion pathways of PM2.5 in Xi'an. |
