2015年喀什市大气颗粒物的时空分布特征
Spatial and Temporal Distribution of Atmospheric Particulates over Kashgar City in 2015
摘要
Abstract
Based on the air pollutant concentration data collected from 3 environmental monitoring stations in Kashgar City in 2015,spatial and temporal characteristics of atmospheric pollutants were analyzed.The results showed that the general kind of pollution was PM (particulate matter), including PM10 and PM2.5 pollution.PM had clearly seasonal variations,the average concentration of PM10 were the highest in spring (504.2 μg·m-3),the lowest in winter (222.6 μg·m-3),and autumn (264 μg·m-3)and summer (239.6 μg·m-3)in between.The average concentration of PM2.5 were the highest in winter(145.9 μg·m-3),the lowest in summer(77.6 μg·m-3),and spring(132.2 μg·m-3) and autumn (118.8 μg·m-3)in between.In addition,the PM2.5 to PM10 ratio was 86% in December, the result showed that the main pollution was PM2.5 in winter. The daily variety indicated that the concentration of PM presented the shape of "3-peak-3-valley"in spring and summer,"double-peak"in autumn and winter.The highest daily concentration of both PM10 and PM2.5 occurred at midnight in summer,around 13:00 in other seasons.The lowest daily concentration of PM10 occurred early in the morning,however, that of PM2.5 occurred in the late afternoon.From the spatial distribution,the concentration of both PM10 and PM2.5 was low in the north of the city,high in the southeast.关键词
