天津市开放源可吸入颗粒物污染问题分析

The Analysis of PM_(10) Pollution from Open Source in Tianjin

通过高斯面源反演的计算方法对天津市扬尘污染源进行反演计算,建立开放源可吸入颗粒物污染源强数据库,系统分析了城市扬尘污染问题。数值试验模拟结果表明,扬尘控制措施与环境质量呈现很好的线性相关关系,通过模拟2004年天津市建筑施工扬尘对城市可吸入颗粒物污染贡献,提出扬尘污染问题解决方案。

With the development of the city structure, the pollution of PM;o from open source become more serious than ever in Tianjin. In this article the source strength of dust from open sources was estimated by inversing Guass area source formula. The database of PMlo source strength was established and the pollution of the dust from open source was systems analysised. The numeric studies showed that the relation of measure to control dust from open source and the concentration of PM10 is linear. Then put forward some strategies in how to solve the problem of open source pollution through simulating the dust contribution from the open sources of construction sites to PM10 in 2004 in Tianjin.
