Abstract： In order to accurately analyze the temporal and spatial distribution characteristics of haze-causing particulate matter in the air in the coastal area of Lianyungang City， with Xuwei New Area as an example， based on the data of six air quality monitoring stations and meteorological data of the same period from March 2019 to February 2020， the quarterly， monthly and weekly mean values of PM2.5 were statistically analyzed and compared horizontally and vertically， and the correlation between air pollutants and meteorological elements was analyzed in this paper.

Keywords： PM2.5; temporal and spatial distribution; meteorological conditions; coastal areas
