    Abstract:

    To explore the blocking impact of plant communities on atmospheric particulate matters,we monitored the PM2.5 and PM10 concentrations and related meteorological factors near plant communities in three functional areas of Zhengzhou's Jinshui district,which were garden area (Digital Park),residential area (Zhengzhou Blue Bay),and cultural & educational area (Henan Agricultural University).The monitoring period covered a whole winter from December 2020 to February 2021.The results indicated that the diurnal variation trends of PM2.5 and PM10 concentrations were basically the same for all sampling plots,which were generally high in early morning and low in evening;obvious differences in PM2.5 and PM10 concentrations were observed among plant communities,which were most significant between the square plot and other plots;for the three functional areas,the blocking of PM2.5 and PM10 were all the strongest by the combined structure of arbor,shrub and grass,followed by arbor & shrub and arbor & grass structures,and the lowest by structure of shrub & grass and single structure of grass;the PM2.5 and PM10 concentrations were observed to be negatively correlated with temperature and wind speed,and positively correlated with relative humidity.
