【摘要】 根据植物对大气污染的反应方式来选择城市绿化树种是减轻大气污染的重要途径和手段。通过观察污染地区绿化树种叶片的受害症状来判断植物对以氯为主要污染物的抗性程度,根据植物对其污染物的反应特性划分植物的抗性等级,筛选出对以氯为主要污染物的抗性植物种类和敏感监测植物种类,从而为绿化植物的合理选用提供依据。结果表明,抗性树种有:花曲柳、桑树、皂角、旱柳、柽柳、忍冬、枸杞、水蜡、紫穗槐、桂香柳、叶底珠、卫矛、刺槐、山桃、木槿、榆树、枣树、臭椿;敏感监测树种有:油松、锦带花、榆叶梅、糠椴、山杏、连翘、糖槭、云杉、桧柏、白桦。更多还原

【Abstract】 In order to reduce air pollutants, it is very important to choose urban planting tree species according to the reaction modes of plants on the air pollution. Through observing damage symptoms of leaves of planting trees in the polluted areas, we estimated resistant degrees of plants to chlorine-dominant pollutants. We classified resistant levels of plants according to their reaction characteristics on their pollutants. As a result, we screened out resistant and sensitive monitoring plant species. The result can be applied to the selection of resistant plant species for planting. It shows that the resistant species include: Fraxinus rhynchophylla, Morus alba, Gleditsia japonica, Salix matsudana, Tamarix chinensis, Lonicera japonica, Lycium chinense, Ligustrum obtusifolium, Amorpha fruticosa, Elaeagnus angustifolia, Securinega suffruticosa, Euonymus alatus, Robinia pseudoacacia, Prunus davidiana, Hibiscus syriacus,Ulmus pumila, Zizyphus jujuba, Ailanthus altissima. And the followings are some sensitive monitoring species: Pinus tabulaeformis, Weigela florida, Prunus triloba,　Tilia mandshurica, Prunus armeniaca var. ansu, Forsythia suspense, Acer saccharum, Picea koraiensis ,Sabina chinensis, Betula platyphylla更多还原
