以抗风性状相关的林木类型、树高、胸径、冠幅、冠形、干形通直度、气干密度、叶层状况、根系状况等9个性状作为园林绿化树种综合评价指标,利用综合评价法和灰色关联度法建立园林绿化树种综合评价与分级模型。对湛江市常见的82种绿化树种进行综合评价与分级,结果为:Ⅰ级树种19种、Ⅱ级树种20种、Ⅲ级树种31种、Ⅳ级树种12种,其中灰色关联度评价法比综合评价法能更好地对树种抗风性进行评价和分级。

In terms of tree type, tree height, diameter at breast height, crown width, stem strength, wood density, foliage layer and root morphology, which were all related with the wind-resistance, graduation and comprehensive evaluation of tree species wind-resistance were studied by comprehensive evaluation and grey relational grade method in this paper.For 82 tree species in Zhanjiang city, the classification result was that:They were classified into four classes including class Ⅰ with 19 species, class Ⅱ with 20 species, class Ⅲ with 31 species and class Ⅳ with 12 species, and grey relational grade was much fitter to evaluate and grade the wind-resistance of tree species than comprehensive evaluation.
