PM2.5源解析及其控制策略研究
摘要
随着工业化、城市化的快速推进，PM2.5（细颗粒物）污染已成为全球范围内普遍关注的环境问题。PM2.5因其粒径小、比表面积大、吸附性强等特点，能深入肺部甚至进入血液循环系统，对人体健康构成严重威胁。PM2.5也是导致大气能见度降低、加剧雾霾天气、影响气候系统的重要因素。解析PM2.5的来源，探索有效的控制策略，对于改善空气质量、保护生态环境、维护公众健康具有重要意义。本文首先阐述了PM2.5的基本概念、特性及主要来源分类，包括自然源与人为源的详细解析。从大气环境、气候系统及人体健康三个维度深入分析了PM2.5的广泛影响，揭示了其作为重要污染物的危害性。在源解析方法与应用部分，本文详细介绍了源解析的基本原理与流程，并对比了常用源解析技术的优缺点，重点探讨了受体模型和排放清单法在PM2.5源解析中的具体应用与案例分析。本文还关注了源解析结果的验证与评估方法，以确保解析结果的准确性和可靠性。基于前述研究，本文提出了PM2.5控制策略的基本原则与目标，从源头控制、过程控制与末端治理、综合治理与区域联防联控等多个方面提出了具体控制措施，旨在为PM2.5污染防治提供全面、系统的解决方案。

Abstract
With the rapid advancement of industrialization and urbanization, PM2.5 (fine particulate matter) pollution has become a widespread environmental concern around the world. Due to its small particle size, large specific surface area and strong adsorption characteristics, PM2.5 can penetrate deep into the lungs and even enter the blood circulation system, posing a serious threat to human health. PM2.5 is also an important factor leading to reducing atmospheric visibility, exacerbating haze weather, and affecting the climate system. The sources of PM2.5 and exploring effective control strategies are of great significance for improving air quality, protecting the ecological environment and maintaining public health. This paper first expounds the basic concepts, characteristics and main source classification of PM2.5, including the detailed analysis of natural sources and anthropogenic sources. The extensive impact of PM2.5 is deeply analyzed from three dimensions of atmospheric environment, climate system and human health, and then its harmfulness as an important pollutant is revealed. In the part of source analysis method and application, this paper introduces the basic principle and process of source analysis in detail, compares the advantages and disadvantages of commonly used source analysis technology, and focuses on the specific application and case analysis of receptor model and emission inventory method in PM2.5 source analysis. This paper also focuses on the validation and evaluation of the source resolved results to ensure the accuracy and reliability of the resolved results. Based on the above research, this paper puts forward the basic principles and ob jectives of PM2.5 control strategy, and puts forward specific control measures from the aspects of source control, process control and terminal treatment, comprehensive control and regional joint prevention and control, aiming to provide a comprehensive and systematic solution for PM2.5 pollution prevention and control.
