利用地衣群落监测SO_2的污染

USING LICHEN COMMUNITIES AS SO_2 POLLUTION MONITORS

本文研究了二氧化硫浓度梯度变化对地衣群落的影响。采用数量分析的方法,研究了受二氧化硫影响的地衣群落间的相似性。通过调查区冬季二氧化硫等值图表明,二氧化硫浓度变化是造成地衣群落间相似性的主导因素。在城市周围,可以用数量分析的方法分类判别地衣群落,从而确定二氧化硫的污染程度和范围。

Using quantitative analysis, the change of SO_2 level in air affecting lichen communities was researched in Nanjing city, China. Pattern of mean SO_2 in winter shows that SO_2 level is the main factor that impact on relativity of lichen communities. The result states that we can make know about SO_2 pollution concentration and scale by means of qaantita-tive analysis of lichen communities.
