【摘要】 对包头34种园林植物的固碳、吸热、滞尘、硫含量、氟含量5个生态功能进行了测定,并应用灰色关联度分析法对它们进行评价。结果表明:紫穗槐具有最高的日固碳能力,卫矛的吸热能力最强,云杉、桧柏的滞尘能力最强,柳树的硫含量最高,新疆杨的吸氟力最强,乔灌木的固碳、吸热、滞尘、叶片吸硫吸氟的关联数值均高于草坪植物,落叶乔木在固碳、吸热方面高于针叶植物、但在滞尘方面低于针叶树,关联系数最高植物:白蜡、紫穗槐、卫矛、垂柳、河北杨、皂角、国槐、暴马丁香、杜松、新疆杨、云杉、家榆等,它们为园林绿化常用植物,表明了包头市园林树种的选择基本实现生态化。更多还原

【Abstract】 Ecological functions of 34kinds of garden plants were measured in terms of their carbon sequestration,heat absorption,dust holding,sulfur content and fluorine content using gray correlation analysis method.The results showed that amorpha has highest carbon sequestration;Euonymus endothermic has highest heat absorption;spruce and cypress is strongest in dust holding;willow has strongest capacity in sulfur absorption;Populus is strongest in fluorine absorption.Shrubs and trees have higher correlation values in carbon sequestration,heat absorption,dust holding,and sulfur and fluorine absorption than lawn plants.Deciduous trees perform better than coniferous plants in carbon sequestration and heat absorption but less in dust holding than conifers.Ash,Amorpha,Euonymus, willow,Populus alba,saponins,Sophora japonica,Syringa reticulate,juniper,Populus bolleana Lauche,spruce and elm have highest correlation coefficient更多还原
