摘　　要：扬尘多为细小的颗粒物,不仅造成大气污染还严重威胁到人类的身体健康。为更加有效地控制扬尘扩散,文章针对排放因子、活动水平数据来源等方面,对比分析了施工扬尘、堆场扬尘、道路扬尘和土壤扬尘的排放量估算方法。结果表明,在估算扬尘排放量时,不同扬尘源获取排放因子、活动水平及估算排放量的方法存在一定差异;排放因子法使用最普遍,直接测量法所得数据最准确,但两种方法的缺点明显。因此建立多方法相结合的估算体系,以此确定最为经济和准确的排放量数据,为城市扬尘控制及日常环境管理提供参考和建议。Dust is mostly fine particulate matter,which not only causes air pollution but also poses a serious threat to human health.In order to control dust dispersion more effectively,this paper compares and analyzes emission estimation methods for construction dust,landfill dust,road dust and soil dust with respect to emission factors and activity level data sources.The results show that in estimating dust emissions,there are some differences in the methods of obtaining emission factors,activity levels and estimating emissions from different dust sources.The emission factor method is the most commonly used,and the data obtained from the direct measurement method is the most accurate,but the disadvantages of the two methods are obvious.Therefore,a multi-method estimation system is established to determine the most economical and accurate emission data,and to provide references and suggestions for urban dust control and daily environmental management.
