摘要
城市大气环境质量是人们生活环境评价的重要组成部分,大气污染造成空气质量下降影响人类健康。对城市大气环境质量进行分析是有效解决其污染防治的前提条件。本研究以湖南省14个城市的大气环境指标PM2.5值为研究对象,通过环境监测平台查询2015年和2016年的大气环境数据进行统计分析。结果得出:从2015年到2016年湖南省14个城市年度大气PM2.5变化范围由44至57下降至40至54。影响大气环境质量的主要污染物是工业排放产生的二氧化硫、氮氧化物和大气烟尘等。在此研究基础上提出了城市大气环境污染的一些防治措施,通过认识大气污染特点到治理大气污染,建设绿色环保的城市发展方式。
The quality of urban air environment is an important component of people＇s living em ironment evaluation, when the air pollution is serious, the formation of fog and haze. The analysis of urban air quality is the precondition to solve the problem of pollution prevention and control. In this study, the PM2.5 value of atmospheric environmental indicators in 14 cities of Hunan province was taken as the object of study and Statistical data for the past 2015 and 2016 are analyzed. The results showed that from 2015 to 2016, the annual variation of atmospheric PM2.5 in 14 cities in Hunan decreased from 44 to 57 to 40 to 54. Atmospheric pollutants are mainly industrial emissions of sulfur dioxide, nitrogen oxides and atmospheric dust and so on. On the basis of this study, some prevention measures for urban air pollution are put forward. Through knowing the characteristics of air pollution, to control air pollution and build a green urban development.
