摘要
为了探析不同用地的大气污染情况,文章选取了沈阳市和大连市的5种用地类型地块作为研究区,基于移动监测法对地面大气颗粒物浓度进行水平分布的实地监测,采用地理探测器模型探究PM2.5浓度与城市环境因子之间的影响机制.结果表明,在不同功能的区域中,土地利用性质不同,影响大气污染物空间分异的主要因素根据实际情况也有所不同.居住、工业、文教、旅游、商业区内影响大气污染物浓度的最主要因子分别是街道走向、天空开阔度、近水距离、贴线率和交通量,最主要因子与其他因子的交互增强作用也相对明显.
Abstract
In order to explore the air pollution of different land uses,this study selected five land types in Shenyang and Dalian as the study area,and used the mobile monitoring method to monitor the horizontal distribution of surface atmospheric particulate matter concentration,and used the geographic detector model to explore the influence mechanism between PM2.5 concentration and urban environmental factors.The results show that the main factors affecting the spatial differentiation of air pollutants are different according to the actual situation in different functional areas,and the land use properties are different.The most important factors affecting the concentration of air pollutants in residential,industrial,cultural,educational,tourism,and commercial areas are street direction,sky openness,water distance,line attaching rate,and traffic volume.The interaction between the most important factor and other factors is also relatively obvious.
