乌鲁木齐街区形态对空气质量的影响研究——以友好北路街区为例

Study on the Influence of Block Form on Air Quality in Urumqi——Taking Youhao North Road Block as an Example

  • 摘要: 以乌鲁木齐友好北路街区为研究对象,采用定点监测法收集数据,分析了街区空气污染物的空间变化特征,探讨了气象因子和形态因子对污染物的影响。结果显示:NO2的空间分布具有较强的自相关性,PM2.5的空间分布较为分散,NO2和PM2.5与气象因子有显著相关性;建筑密度、高度、容积率与污染物呈正相关,天空视域因子呈负相关,道路密度与污染物也呈正相关。

     

    Abstract: In this study, Urumqi was taken as the research object. The data was collected by fixed-point monitoring method and analyzed the spatial variation characteristics of air pollutants in the neighborhood. The effects of meteorological factors and morphological factors on pollutants were discussed. The results showed that the spatial distribution of NO2 had a strong autocorrelation, and the spatial distribution of PM2.5 was scattered, and NO2 and PM2.5 had a significant correlation with meteorological factors. Building density, height, and floor area ratio were positively correlated with pollutants, while sky sight shed factor was negatively correlated, and road density was also positively correlated with pollutants.
