阜新市大气污染分布规律研究

以阜新市1996-2000年大气环境监测数据为基础,采用污染负荷系数法,分析了半干旱区域的资源型城市大气污染分布规律,揭示了城市环境空气污染物随季节、年际、功能区变化的规律,并分析了形成这种规律的原因.结果表明,阜新市大气污染物的浓度具有明显的时空分布规律,时间上表现为年内冬强夏弱,年际间自1996年以来总悬浮颗粒和一氧化碳逐年减轻;空间上,空气污染物的浓度依功能区不同而异,交通区的污染状况最严重.

Study on distribution regularity of air pollution in Fuxin City

On the basis of air monitoring data published in Fuxin City from 1996 to 2000,this paper has made an analysis on the distribution regularity of the air pollution in a coal-resource city of half arid area by means of pollutant load rates.Our analysis reveals the regularity of air pollutant activities in the urban environment of Fuxin changes with different seasons,years as well as the different functions of areas of the city.At the same time the paper has analyzed the reasons for forming such given regularity.The results are described as follows: there exist remarkable time and position distribution regularity of concentration of the atmospheric pollution in Fuxin,with the highest concentration of pollutant activities was monitored in winter and the lowest one in summer.From 1996 to 2000,the pollutant loading rates of DF and CO proved to be declining by and by.Whereas the pollutant loading rate of each atmospheric pollutants changes with the areas of different functions,with pollution of traffic area being the most serious.Thus,the analysis provided here can offer a scientific basis for preventing further more serious air pollution.
