摘 要
生物质燃烧作为一种重要的能源利用方式，在全球范围内广泛存在，尤其在发展中国家和农村地区，其对区域大气环境质量的影响日益受到关注。本研究旨在系统评估生物质燃烧对大气污染物排放特征及其环境影响，通过选取典型生物质燃料类型，采用在线监测与离线分析相结合的方法，获取了详细的化学组成数据，并结合气象参数建立了三维数值模型进行模拟分析。研究表明，生物质燃烧是颗粒物、挥发性有机物及一氧化碳等污染物的重要来源，其中细颗粒物（PM2.5）占比显著，且含有较高浓度的多环芳烃等有害物质。不同燃烧条件下污染物排放因子差异明显，优化燃烧条件可有效降低污染物排放量。

Abstract
As an important way of energy utilization, biomass combustion is widely present around the world, especially in developing countries and rural areas, and its impact on regional atmospheric environmental quality is increasingly attracting attention. The purpose of this study is to systematically evaluate the characteristics of biomass combustion on air pollutant emissions and their environmental impact. Select typical biomass fuel types and combine on-line monitoring and offline analysis to obtain detailed chemical composition data, and establish a three-dimensional numerical model based on meteorological parameters. Studies have shown that biomass combustion is an important source of pollutants such as particulate matter, volatile organic compounds, carbon monoxide and other pollutants, among which fine particulate matter (PM2.5) accounts for a significant proportion, and contains high concentration of polycyclic aromatic hydrocarbons and other harmful substances. The pollutant emission factors differ significantly under different combustion conditions, and optimizing the combustion conditions can effectively reduce the pollutant emission.
