摘要：绿化树种是改善环境的载体,叶片是大气污染物的吸收器,于2011年选择新乡市26种绿化树种(不同的季节和功能区),对其叶片氯含量进行分析,结果表明,26种绿化树种叶片氯含量随春、夏、秋季节的变化呈现递增趋势,针对较清洁的校园而言,污染严重的工业区所有绿化树种叶片氯含量都较高。运用K-均值聚类法对城市绿化树种叶片氯含量进行分类,大叶黄杨、紫丁香、卫矛、杨树和大叶女贞叶片含氯量相对较高,归为第1类;臭椿、榆树、五角枫、榆叶梅、栾树、小叶黄杨、银杏和构树叶片氯含量居中,归为第2类;第3类包括连翘、毛泡桐、毛白杨、紫荆、国槐、椤木石楠、枇杷、白玉兰、红叶石楠、凤尾兰、垂柳、紫叶李和白蜡,叶片氯含量相对较低。
The afforest tree is an important supporter in environmental improvement and whose foliage is an absorber of atmospheric pollutants,26 afforestation trees were chosen in different seasons and functional areas in the year of 2011 in Xinxiang,and the foliage chlorine contents of different trees was mensurated.The results indicated that the chlorine contents of the afforest trees＇ leaves increased according to seasonal variation of spring,summer and autumn.In comparison with clean areas,the chlorine contents of all the trees were relatively high in severely polluted industial areas.The foliage chlorine contents of different afforestation trees could be classified by K-Means Cluster,Buxus megistophylla,Syringa oblate,Euonymus alatus,Populus canadensis,Ligustrun lucidum,were classified as the first category and their chlorine contents were relatively high.The second category included Ailanthus altissima,Ulmus pumila,Acer elegantulum Fanget,Amygdalus triloba,Koelreuteria paniculata,Buxus sinica,Ginkgo biloba and Papermulberry,their chlorine contents were in the medium.The third category included Forsythia suspense,Paulownia,Populus tomentosa,Cercis chinensis,Sophora japonica Linn,Photinia davidsoniae,Eriobotrya japonica,Magnolia denudate,Photinia serrulata,Yucca gloriosa,Salix babylonica,Prunus cerasifera and Fraxinus chinensis,their foliage chlorine contents were relatively low.
