GIS辅助的吴淞工业区铺设道路扬尘估算

Estimation of fugitive dust emission from paved roads in Wusong industrial estate based on GIS

本文以上海市的吴淞工业区为研究对象,借鉴美国EPA提出的AP-42方法,利用动力学粒径谱仪的粒径分析结果对公式系数进行修正,在GIS手段的辅助下对吴淞工业区铺设道路不同粒径的扬尘量进行估算,最终由V isualBasic语言和MapObjects2.0组件建立的铺设道路扬尘管理信息系统表明GIS的使用有利于加强扬尘污染的研究和控制。

In this article,GIS was assisted to estimate the fugitive dust emission inventory of paved roads with the method of AP-42 provided by EPA in Wusong Industrial Estate.One of the parameter,k,particle size multiplier,was corrected by using the Aerodynamic Particle Sizer to analyse the particle size of silt loading for the first time.The MIS of fugitive dust from paved roads established by Visual Basic and MapObjects 2.0 showed that GIS was propitious to the study and control of fugitive dust pollution.
