摘要
[目的]明确不同园林植物的生态功能,为景观合理配置提供科学依据。[方法]对内蒙古包头市32种园林绿化植物的固碳、吸热、滞尘以及叶片氮、硫含量共5个生态功能指标进行测定,并应用灰色关联度分析法进行综合量化评价。[结果]不同生活型植物的生态功能差异明显,总体关联度从大到小为乔木、灌木,落叶植物、常绿植物;常绿乔木、落叶乔木和灌木中关联度最大的分别是杜松、白蜡和紫穗槐,樟子松、龙爪槐和桑树、珍珠梅和沙枣最小;不同类型绿地的生态功能关联度从大到小为乔灌草型、乔灌型、乔草型、灌草型、草坪型。[结论]应充分利用这些植物最优的生态功能进行乔、灌、草合理搭配,营造出更大的绿化率,最大程度地发挥城市绿地的生态效益。
[Objective] To provide scientific basis for rational configure of landscapes by clarifying the ecological functions of different garden plants.[Method]5 ecological function indexes（ carbon fixation,endotherm,detaining dust,sulfur content,fluorine content） of landscape plants of 32 kinds in Baotou City of Inner Mongolia were determined,and applied grey relational degree analysis to conduct comprehensive quantitative evaluation.[Result]The difference of ecological function of different life type plants was obvious.The order of total correlation degree from high to low was tree,shrub,deciduous plant,evergreen plant.The greatest correlation degrees of evergreen trees,deciduous trees and shrubs were respectively Juniperus rigida,Fraxinus chinensis and Amorpha fruticosa.The smallest correlation degrees were respectively Pinus sylvestris var.mongolica in evergreen trees,Sophora japonica and Morus alba in deciduous trees,Sorbaria sorbifolia and Elaeagnus angustifolia in shrubs.The correlation degree order of ecological function of different types green space from high to low was tree-shurb-grass type,tree-shurb type,tree-grass type,shurb-grass type,lawn type.[Conclusion]We should make full use of the best ecological functions of these plants,make reasonable collocation of trees and grass,create a greater green rate,and maximize the ecological benefits of urban green space.
