| 摘 要： | 本文简要回顾了我国中、新生代典型中酸性火山活动的气候环境效应的研究进展,重点讨论了新生代长白山天池火山喷发和中生代辽西火山活动对气候环境造成的影响。天池火山气体含量呈现两个相同趋势的旋回式变化,从早到晚,卤化物和H2O呈降低趋势,而硫化物气体呈增加趋势。火山旋回早期富含HF气体导致动物窒息、甚至大批集群死亡;晚期喷出的大量硫化物气体可以形成大规模酸雨和剧毒火山灰云幕,对周围的动植物生长有严重影响。辽西火山气体可分为三种组合,形成酸雨,导致地表温度下降,加速臭氧浓度降低,甚至破坏臭氧层,从而对生物的生存环境造成严重危害。

| Abstract: | This paper has briefly reviewed advances of the research on environmental and climate impact caused by the Mesozoic and Cenozoic volcanism in China,especially has discussed the environmental and climate impact in the Changbaishan and western Liaoning areas caused by the Cenozoic volcanic eruption of the Tianchi volcano in the Changbaishan area and the Mesozoic volcanism in the western Liaoning area as the volcanic eruption could emit huge amounts of volatiles and resultant aerosols into atmosphere and could change the environment and climate.There are two cycles for the variation of volcanic volatiles of the Tianchi volcano.From the early stage to late stage of a volcanic cycle,the halogenide and H2O contents are decreased,whereas the sulfuric gas is increased.High content of HF is contained in the volatiles emitted out in the early stage of the volcanic cycle.It could cause animal suffocation or death in large scale.A large amount of sulfuric gases contained in the late stage volatiles could form acid rain and poisonous volcanic clouds in large scale and severely influence the growth of animals and vegetations in the surrounding area.The acid rain formed with 3 groups of volcanic volatiles of the western Liaoning area,resulted in the decrease of surface temperature,the decrease of ozone content or the broken of ozonosphere,and further severely damage the living environment of organisms. |
