摘要
根据柳树叶片能吸收、累积二氧化硫的能力,研究了盘锦市主要大气监测点位附近柳树对硫的吸收、积累特点和净化作用。结果表明:春季叶片含硫量低于夏季,成熟叶大于幼叶,叶片含硫量能指示出不同地区(点位)的大气污染状况,反应该地区的环境质量。
Based on the theory about vegetable laminas have the capacity of absorbing and accumulating sulfur dioxide , A study on absorbing characteristics and accumulating mechanism was conducted using willow leaf , which were taken around JinZhou atmospheric monitoring station . the results shows that sulfur content in spring was lower than that in summer and sulfur content in mature leaf was higher than that in immature one , this paper believes that different sulfur content in plant laminas can reflect different sulfur dioxide pollution level and air quality.
