【摘要】 SO₂和NO₂为我国大气污染主要污染物,城市森林对SO₂和NO₂具有一定的抵抗能力和吸收净化能力,利用城市森林对大气污染进行修复具有良好的应用前景。文章概述了我国SO₂和NO₂气体污染的状况,总结了污染物进入植物体的过程及其损伤机理,并从植物抗性和吸附净化能力两方面总结了城市景观树种与SO₂和NO₂气体污染的关系研究,并基于研究结论提出今后研究可能发展方向,如SO₂、NO₂与悬浮颗粒物等复合污染对城市树种生长的影响、树种抗性和吸附能力综合研究等。更多还原

【Abstract】 SO₂ and NO₂ are the major pollutants of the air pollution in China. Urban forest has the certain resistance and purification capacity to SO₂ and NO₂, and it has a good application prospect of the restoration of air pollution. This paper summarizes the status of SO₂ and NO₂ gas pollution in China, and the process of pollutant entering the plant body and its damage mechanism. The paper also summarized the relationship between urban landscape tree species and the SO₂ and NO₂ gas pollution from the aspects of the plant resistance and purification capacity. Based on the conclusions of the study, the possible research directions, such as the effects of SO₂, NO₂ and suspended particulate matter on the growth of urban tree species, comprehensive study of the tree species resistance and absorption capacity are put forward.更多还原
