城市地表灰尘的概念及其研究现状分析

Concept and Research Status of Urban Surface Dust

城市地表灰尘污染已经成为人们生活中不可回避的一个重要环境污染问题,严重影响着人们的生活、学习和工作。国外对相关领域起步较早,并取得了一定的研究成果,国内对该领域起步晚,研究少。本文就城市地表灰尘的概念的理解及来源做了系统的介绍,并提出了新的理解,重点突出了地表灰尘的来源及特点。在此基础上介绍了国内外在相关领域的主要研究内容及研究方向,地表灰尘对城市生态环境具有指示作用,其污染物质的迁移和转化直接影响着城市的水圈、大气圈、土壤圈等。最后,讨论了有关生态风险并提出了切实可行的治理方法。

Urban surface dust pollution has become a major environmental issue that cannot be avoided in people's lives. It has great impacts on people's lives,study and work. Related fields about urban surface dust pollution abroad started earlier,and made certain achievements,but China started late and few. This article introduces the concept and source of urban surface dust,meanwhile propose a new understanding that highlights the source and characteristic of urban surface dust. This paper introduced the main research content and research direction in related fields at home and abroad. Urban surface dust is an important indication to urban ecological environment,the migration and conversion of pollutants of that which directly affects the hydrosphere,the atmosphere and pedosphere of the city. Finally,this article discusses the ecological risks of urban surface dust and put forward practical control measure.
