摘要
Abstract
In order to understand the characteristics and sources of atmospheric precipitation components in Bozhou,the time series analysis method was used to process the weighted average data of atmospheric precipitation monitoring factors,and further analyze the long-term evolution trends and characteristics of each monitoring factor.Research showed that the pH range of precipitation in Bozhou from 2016 to 2023 was between 6.36 and 7.11,and the incidence of acid rain was 0%.The range of precipitation conductivity was between 11.89 and 56.82 mS/m,and the annual precipitation was between 31.72 and 258.2 mm.The order of ion concentrations in chemical components was SO42->NO3->Ca2+>Na+>K+>Cl->Mg2+>NH4+>F-,and there was a certain correlation between the components.There was also a significant positive correlation between SO42-、Ca2+、Na+、electrical conductivity and coal consumption,as well as between NO3-,Na+and the number of car ownership.Cluster analysis was used to classify the possible sources of precipitation ions into three major categories,accounting for 65.7%,31.6%and 2.7%respectively,and corresponding prevention and control countermeasures and suggestions were proposed.关键词
