【摘要】：农业活动是一个重要的大气污染物排放源。随着我国工业污染物减排措施的不断加强,以及我国农业现代化发展进程的加快,农业活动的污染物排放对大气环境的影响将日益突出。综述了农业活动排放大气污染物的基本形式和影响大气复合污染的主要机理,分析了农业活动的污染物排放及其大气环境效应模拟研究现状;并提出了面临的主要问题:1农业排放源估算和排放源清单制定的不确定性;2PM2.5与农业排放各前体物之间呈高度非线性关系;3现有空气质量模式仍缺乏对PM2.5及其化学组成的认识以及对PM2.5形成机理和形成过程的描述,对PM2.5浓度及其化学组分预报的准确性不够。
[Abstract]:Agricultural activity is an important emission source of atmospheric pollutants. With the enhancement of emission reduction measures for industrial pollutants and the acceleration of agricultural modernization in China, the impact of pollutant emission from agricultural activities on the atmospheric environment will become increasingly prominent. This paper summarizes the basic forms of atmospheric pollutants discharged from agricultural activities and the main mechanism that affect the atmospheric compound pollution, and analyzes the present situation of the research on the emission of pollutants from agricultural activities and the simulation of atmospheric environmental effects. The main problems are as follows: (1) the uncertainty of agricultural emission source estimation and emission source inventory, the highly nonlinear relationship between 2PM2.5 and agricultural emission precursors; (3) the existing air quality models still lack the understanding of PM2.5 and its chemical composition, the description of the formation mechanism and process of PM2.5, and the accuracy of prediction of PM2.5 concentration and its chemical components.
