城市尘土地球化学调查的意义及构想

Significance and Idea for Urban Dust Geochemical Survey

城市生态系统是一个自然与人工生态环境的复合体 ,由于调查、观测的介质不易确定和采样条件限制 ,常是地球化学调查工作的盲点。目前环保部门对城市环境质量监测主要是大气和水质 ,而城市尘土这个与城市人类生活密切相关的介质没有引起研究者的关注。本文从环境生态学及地球化学的角度 ,简述了城市尘土地球化学调查的意义及构想。

Urban ecological system is a compound of natural and artificial ecological environments. It is difficult to determine detected media for urban ecological environment survey. Environmental protection departments detect atmosphere and water in order to monitor urban environment, however, urban dust is in close relationship with human daily life. This paper outlines significance and idea for urban dust geochemical survey in terms of environmental ecology and geochemistry.
