2016年含山县PM_(2.5)的污染特征及与气象要素的相关性分析

The Correlation Analysis between Meteorological Elements and PM_(2.5) Pollution Characteristics in Hanshan County in 2016

当前,随着生态文明建设的深入实践,人们的环保意识不断提高,空气质量作为判别环境好坏的直观标准之一,愈发受到社会关注。该文研究了2016年含山县大气污染物PM_(2.5)的变化特征,对PM_(2.5)数据进行统计分析,分析含山县PM_(2.5)的污染水平,然后重点探究了PM_(2.5)质量浓度日数据与气象要素气压、气温、湿度、降水量、风速的相关性。结果表明:含山县1月、2月、3月、12月的PM_(2.5)污染较为严重,PM_(2.5)日平均质量浓度与气压正相关,与气温、湿度、降水量、风速负相关。该文结论可以为当地通过气象要素的变化分析预测空气质量提供参考依据。

Currently,with deepening practice of ecological civilization construction and continuous improve-ment of people's awareness of environmental protection,the air quality has been considered as one of thevisible standards to judge the environment status and got more and more attention from the social public.This thesis makes research on the change characteristics of air pollutant PM_(2.5) in Hanshan County in 2016,and focuses on the study about the correlation between daily data of PM_(2.5) mass concentration and meteoro-logical elements including atmospheric pressure,temperature,humidity,precipitation and wind speed,etc.Theresult shows that,the PM_(2.5) pollution of Hanshan County was serious in January,February,March and Decem-ber,and PM_(2.5) daily average mass concentration is positively correlated with air pressure,but negatively corre-lated with temperature,humidity,precipitation and wind speed.The conclusion of this thesis can provide the-oretical reference to local meteorological research center for predicting the air quality through analysis onthe change of meteorological elements.
