摘要
2023 年 5 月—2024 年 4 月,PM2.5、PM10、O3 是影响织金县空气质量的主要污染物,其中,PM2.5 为冬季的首要污染物.对比分析发现,燃煤取暖是织金县冬季PM2.5 超标的主控因素.后向轨迹法(Hysplit4)结果显示,织金县冬季PM2.5 浓度超标可能还与周边区域的PM2.5 输入有关,1 000 m高度气流来源差异可能导致局部PM2.5 浓度差异.据此,本文提出了大气污染防治对策,旨在为织金县的大气污染防治提供思路.
Abstract
PM2.5,PM10,and O3 were the main pollutants affecting the air quality in Zhijin County from May 2023 to April 2024,with PM2.5 being the primary pollutant in winter.Comparative analysis revealed that coal-fired heating was the main controlling factor for excessive PM2.5 content.The results of the backward trajectory method(Hysplit4)showed that the excessive PM2.5 concentration may also be related to the PM2.5 input from the surrounding areas,and the difference in air flow sources at a height of 1 000 meters may lead to spatial PM2.5 concentration differences.Based on this,measures for air pollution prevention and control have been proposed,aim to provide ideas for the prevention and control of air pollution in Zhijin County.
