摘　　要：以北京市城区主要35种乔木树种为对象,从树木个体的景观美学角度去选择评价指标,用灰色关联度分析法对现有乔木树种进行景观美学评价,按照灰色系统理论关联度分析原理,关联度大的数列与参考数列最为接近,通过各树种每个景观指标的关联度大小,可以明确各树种的优劣。加权关联序结果表明,雪松、银杏、腊梅、悬铃木、梅花、元宝枫、垂柳、山桃、白蜡和鹅掌楸等在评价上与标准数列最接近,说明综合景观美学效果优良,是北京城市绿化中适宜的景观树种。利用灰色关联分析方法评价城市景观树种,能客观、正确地反应各个树种的优劣,可操作性强,对于城市景观树种的选择具有重要的现实意义。Landscape esthetics evaluation was performed on 35 tree species in Beijing with grey correlation analysis method. According to the principle of correlation degree analysis of grey system theory, the series with a high degree of correlation are closer to the reference sequence. The advantages and disadvantages of each tree species could be identified according to the correlation degree of each landscape index of all tree species. The result of weighted grey relational degree shows that Cedrns deodara, Ginkgo biloba, Chimonanthus praecox, Platanus oreientalis, Prunus mume, Acer truncatum, Salix matsudana, Prunus davidiana, Fro.vinus chinersis and Liriodendron chinense are closest to the ideal tree species in the evaluation. The comprehensive landscape aesthetic effects of the above tree species are better, and they are suitable landscape tree species for urban greening , in Beijing. It is easily operated using the grey relational analysis method to evaluate the urban landscape tree species, and it can also objectively and correctly reflect the merits of various tree species.
