摘 要
大气悬浮颗粒物在大气之中分布范围很广，其化学成分比较复杂，由于其对全球气候和空气质量的影响较大，从而日益引起相关专家的重视，在大气科学中成为了重点的研究对象。由于生态环境的脆弱和人为的不合理的行为因素的影响，云龙区的空气质量受到了严重的污染，空气污染目前已经成为云龙区发展的一个重要制约因素之一。根据2018-2022年5年间云龙区的大气污染情况，对云龙区地区的大气污染现状进行了初步的分析，并对城市大气中总悬浮颗粒的污染情况进行了描述，归纳出城市尘埃污染的空间分布特点，进而明确了总悬浮颗粒物污染产生的原因，并提出了防治总悬浮颗粒的相关对策。

Abstract
Atmospheric suspended particulate matter is widely distributed in the atmosphere, and its chemical composition is relatively complex. Because of its great impact on the global climate and air quality, it has increasingly attracted the attention of relevant experts, and has become a key research object in atmospheric science. Due to the fragility of ecological environment and the influence of artificial unreasonable behavior factors, the air quality of Yunlong District has been seriously polluted, and air pollution has become one of the important constraints for the development of Yunlong District. According to 10 years from 2013-2022 host area of atmospheric pollution, the atmospheric pollution situation of the preliminary analysis, and the pollution of suspended particles in the city atmosphere is described, summarizes the spatial distribution characteristics of urban dust pollution, and clear the cause of the total suspended particulate pollution, and the relevant countermeasures of total suspended particles are put forward.
Keywords: Suspended particles; pollution; prevention and control
