On Comparison of Content of Sulfur,Chlorine and Fluorine in Foliage in 10 Kinds of Afforestation Trees

ZHANG Jia-yang,CHEN Li-li,REN Min

摘要: 为探究绿化树种叶片富集大气污染物的差异性，对新乡市10种道路绿化树种叶片硫、氯和氟的含量进行了分析。结果表明：10种绿化树种叶片硫、氯和氟的含量随春、秋季节的变化呈现递增趋势，硫、氯和氟的递增范围分别为104％～644％、127％～526％和164％～1117％；与清洁区相对照而言，污染区域供试的所有的绿化树种叶片污染物硫、氯和氟的含量都较高，其变化幅度范围分别为108％～342％、167％～503％和116％～421％。根据绿化树种叶片污染物含量的大小将其分成3类，第一类以杨树、臭椿和构树为代表，叶片污染物硫、氯和氟的含量较高；第二类包括悬铃木、紫叶李、榆树和垂柳，污染物含量居中；白蜡、银杏和国槐叶片硫、氯和氟的含量相对较低，归为第三类。其中叶片表面粗糙、具有密集绒毛和沟道组织的园林绿化树木叶片污染物含量较高。

Abstract: To study the differences of the content of sulfur ,chlorine and fluorine in foliage by the afforesta-tion trees w hose level concentrated atmospheric pollutants ,10 kinds of afforestation trees in Xinxiang have been selected .T he results indicate that the content of sulfur ,chlorine and fluorine in foliage show an in-creasing trend with the changes of spring and autumn ,and the increasing range of sulfur ,chlorine and flu-orine are respectively 104% ~644% ,127% ~526% and 164% ~1117% ;Compared with the unpolluted ar-ea ,the content of sulfur ,chlorine and fluorine are higher relatively in polluted areas ,and the changing range of them are 108% ~342% ,167% ~503% and 116% ~421% respectively .It has been divided into three categories according to the pollutant content of foliage in afforestation trees :Populus Canadensis , A ilanthus altissima and Papermulberry are classified to the first category and the content of sulfur ,chlo-rine and fluorine are higher ;The second category ,including Platanus hispanica ,Prunus cerasifera ,Ul-mus pumila and Salix babylonica ,presents medium content of pollutant ;The third category included Fraxinus chinensis ,Ginkgo biloba and Sophora japonica Linn in which the content are lower .The pollu-tant content are higher in foliage with rough surface ,covering with flur and having a channel organization .
