【摘要】：農(nóng)業(yè)活動(dòng)是一個(gè)重要的大氣污染物排放源。隨著我國(guó)工業(yè)污染物減排措施的不斷加強(qiáng),以及我國(guó)農(nóng)業(yè)現(xiàn)代化發(fā)展進(jìn)程的加快,農(nóng)業(yè)活動(dòng)的污染物排放對(duì)大氣環(huán)境的影響將日益突出。綜述了農(nóng)業(yè)活動(dòng)排放大氣污染物的基本形式和影響大氣復(fù)合污染的主要機(jī)理,分析了農(nóng)業(yè)活動(dòng)的污染物排放及其大氣環(huán)境效應(yīng)模擬研究現(xiàn)狀;并提出了面臨的主要問(wèn)題:1農(nóng)業(yè)排放源估算和排放源清單制定的不確定性;2PM2.5與農(nóng)業(yè)排放各前體物之間呈高度非線性關(guān)系;3現(xiàn)有空氣質(zhì)量模式仍缺乏對(duì)PM2.5及其化學(xué)組成的認(rèn)識(shí)以及對(duì)PM2.5形成機(jī)理和形成過(guò)程的描述,對(duì)PM2.5濃度及其化學(xué)組分預(yù)報(bào)的準(zhǔn)確性不夠。
[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.
