在环境大气中非甲烷总烃(NMHC)属于重要污染物,其成分结构较为复杂,种类较多,部分非甲烷总烃化合物具有致癌作用、刺激性和毒性,有时还会形成二次有机气溶胶和光化学烟雾,造成环境污染,严重威胁着生态环境和人体健康.研究绿道规划植被非甲烷总烃排放与大气污染间存在的响应关系具有重要意义.采用光合有效辐射和叶温等基本变量,计算绿道规划植被NMHC排放量,分析不同植被排放的NMHC成分构成,获取了光强和温度对植物排放NMHC速率产生的影响.采用最大增量活性因子法MIR和丙烯等效浓度(Prop-Equiv)研究绿道规划植被NMHC排放与臭氧生成潜势(OFP)之间的关系,进而获得NMHC排放与大气污染之间的响应关系.
Response Relationship between Vegetation NMHC Emissions and Air Pollution in Greenway Planning
Non methane total hydrocarbons are important pollutants in the environmental atmosphere,with complex composition and diverse types.Some non methane total hydrocarbon compounds have carci-nogenic,irritating and toxic effects,and sometimes form secondary organic aerosols and photochemical smog,causing environmental pollution and seriously threatening the ecological environment and human health.The research on the response relationship between non methane total hydrocarbon(NMHC)emis-sions from vegetation and atmospheric pollution in greenway planning is of great significance.The pro-posed method calculated the NMHC emissions from vegetation by using the basic variables such as photo-synthetic effective radiation and leaf temperature,analyzed the NMHC components of different vegetation emissions,and obtained the effects of light intensity and temperature on the rate of NMHC emissions from plants.On this basis,the maximum incremental reactivity factor method(MIR)and propylene equiva-lent concentration(Prop-Equiv)were used to study the relationship between vegetation NMHC emissions and ozone formation potential(OFP)in greenway planning,and to obtain the response relationship be-tween NMHC emissions and air pollution.
