摘要
随着城市化进程的不断推进,由施工建设造成的扬尘逐渐成为城市空气污染的重要原因.以城市为研究对象整体描述污染排放情况,对全面评估施工扬尘的环境影响具有关键意义.因此,结合遥感影像解译和排放因子法,提出一种城市整体视角下的施工扬尘排放清单构建方法.在此基础上建立广州市 2020 年施工扬尘源颗粒物排放清单,并将研究区域使用2 km×2 km网格分布进行排放特征分析,研究结果为进行高空间分辨率的污染物扩散模拟和环境影响评估提供了重要数据基础,并为观察施工污染提供了宏观视角,政府可以此为参考从城市整体出发进行污染监测和治理.
Abstract
As urbanization continues,construction-related dust has emerged as a significant contributor to urban air pollution.A comprehensive evaluation of the environmental impact of construction dust necessitates an understanding of the pollution discharge from an urban perspective.Consequently,this paper proposes a construction dust emission inventory construction method from the urban perspective,which combines remote sensing image interpretation and the emission factor method.On this basis,a particulate matter emission inventory of construction dust sources in Guangzhou in 2020 is established,and the emission characteristics of the study area are analyzed using a 2km×2km grid distribution.The findings of this research provide a crucial data foundation for high-resolution pollutant diffusion simulations and environmental impact assessments.They also offer a macro perspective for observing construction pollution,which can be utilized by the government to monitor and control pollution from an urban perspective.
