摘要:以悬铃木、国槐、白蜡、广玉兰、女贞、石楠、大叶黄杨、小叶女贞、海桐、雪松、圆柏、龙柏12种新乡市道路绿化树木为试材,对新乡市12种道路绿化树木叶片硫、铅和铜的含量进行分析,研究了绿化树木叶片富集大气污染物的差异性。结果表明:除广玉兰和女贞叶片硫含量秋季比春季略有减少外,所有供试绿化树种叶片的硫、铅、铜含量随春、秋季节变化呈递增趋势,硫、铅和铜的递增范围分别为18%~216%、4%~385%和27%~334%;与清洁区相比较而言,污染区域所供试的所有绿化树木叶片污染物硫、铅和铜的含量都较高,其变化幅度范围分别为9%~223%、37%~390%和85%~374%。根据绿化树木叶片污染物含量的综合分析,将其分成3类,第1类以雪松和广玉兰为代表,叶片中含污染物硫、铅、铜的量较高;第2类包括白蜡、女贞、悬铃木和大叶黄杨,叶片中3种污染物含量居中;龙柏、国槐、小叶女贞、圆柏、海桐和石楠叶片硫、铅和铜的含量相对较低,归为第3类。运用隶属函数法对不同类型绿化树种叶片硫、铅、铜含量进行综合分析,结果表明常绿乔木叶片综合污染物含量最高,针叶树种次之,其次是落叶乔木,常绿灌木最低。
Taking Platanus hispanica ,Sophora japonica ,Fraxinus chinensis ,Magnolia grandi flora ,Ligustrun lucidum , Photinia serrulata , Buxus megistophylla , Ligustrurn quihoui , Pittporum tobira , Cedrus deodara , Sabina chinensis, Juniperus chinensis 12 road green trees as materials,to explore the differences of air pollutant amount accumulated byafforestation trees in X.inxiang,the foliage content of sulfur, lead and copper were analyzed. The results showed that the sulfur,lead and copper contents of tree leaves increased according to seasonal variation of spring and autumn,except for Ligustrun lucidum and Magnolia grandifLora. And the increment range of sulfur,lead and copper respectively was 18% -216%-385% and 270%-%. In comparison with cleaning area, the sulfur,lead and copper contenzs of all afforestation trees were relative higher than polluted area,and its increment range respectively was 9%- 223%, 37 % - 390% and 85%-374%. The green tree species were classified on the basis of the comprehensive analysis of leaves contaminant levels. Cedrus deodara and Magnolia grandiflora was classified to the first category and its leave contaminant level was relative higher. The second category included .,;gustrun lucidum, Fraacinus chinensis, Bantus megistophylla and Platanus hispanica. Their leaves contaminant contems were at medium levels, The third category included J uni perus ch inensis , So phora japonica Linn,Ligustrum quihoui , Sabinach inensis , P itl porum tobira and Photinia serrulata. Their leaves contaminant contents were at relative lower levels. Comparing cornprehensionly with the foliage sulfur,lead and copper contents of different type of afforest trees by membership function,it find that evergreen trees were the highest, followed by coniferous species,followed by deciduous trees,evergreen shrubs were the lowest.
