摘　　要：2023年5月—2024年4月,PM_(2.5)、PM_(10)、O_(3)是影响织金县空气质量的主要污染物,其中,PM_(2.5)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PM_(2.5)超标的主控因素。后向轨迹法(Hysplit4)结果显示,织金县冬季PM_(2.5)浓度超标可能还与周边区域的PM_(2.5)输入有关,1000 m高度气流来源差异可能导致局部PM_(2.5)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。PM_(2.5),PM_(10),and O_(3)were the main pollutants aff ecting the air quality in Zhijin County from May 2023 to April 2024,with PM_(2.5)being the primary pollutant in winter.Comparative analysis revealed that coal-fi red heating was the main controlling factor for excessive PM_(2.5)content.The results of the backward trajectory method(Hysplit4)showed that the excessive PM_(2.5)concentration may also be related to the PM_(2.5)input from the surrounding areas,and the diff erence in air fl ow sources at a height of 1000 meters may lead to spatial PM_(2.5)concentration diff erences.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.
