道路交通污染对昆虫的影响

综述了国内外近年来道路交通污染及其空气污染物对昆虫影响的研究状况。介绍了交通污染的现状，阐述了汽车尾气中不同污染物，包括二氧化硫（SO₂）、氮氧化物（NO_x，包括NO和NO₂）、碳氧化物（CO_x，包括CO和CO₂）、挥发性有机物（VOCs）、酸雨和臭氧（O₃），以及细颗粒扬尘等污染物对昆虫发生和种群适合度等的影响，并分析了交通污染影响昆虫的作用机理，指出了国内今后该领域的研究方向。此外，道路交通污染对周边生物环境也会造成相关的生态影响。今后应加强生态道路建设，减轻交通污染对路域生态系统的影响。

Impacts of roadway traffic pollutions on insects

The effects of roadway traffic pollutions and atmospheric pollutants on insects were reviewed based on the recently domestic and international studies.An introduction was presented about the status of roadway traffic pollutions and the impacts of the pollutants of automobile exhausted gas,e.g.,sulfur dioxide(SO_2),nitrogen oxide(NO_x,including NO and NO_2),carbon oxide(CO_x,including CO and CO_2),volatile organic compounds(VOCs),acid rain,ozone(O_3)and particulate matters(PM),on the occurrence,performance and population fitness of insects,and the function mechanisms of the above pollutants were also elucidated.Moreover,some topics about the impacts of roadway traffic pollutions on insects were also provided to advise the future research in China.Furthermore,some ecological effects on peripheral environment of road-region ecosystems were also caused by roadway traffic pollutions.In the future,the constructions of ecological roadways should be reinforced in order to alleviate the adverse impacts of traffic pollutions on road-region ecosystems.
