摘　　要：为了对武威市绿化树种现状进行分析评价,选择武威市城区典型绿化区域对绿化树种构成、应用频度、生活型、开花特性、观赏特性、生态适应性及应用形式进行调查,结果表明,武威市建成区共有城市绿化树种113种(含变种、变型、品种),其中常绿树种18种,落叶树种95种;乔木48种,小乔木25种,灌木42种,藤本3种;观花树种50种,观叶类树种28种,观果类树种15种,观枝类树种6种;完全适应当地气候条件树种78种,基本适应25种,适应较差10种;栽植方式有孤植、列植、对植、丛植、丛植、群植等6个,配置模式有乔+灌+草、乔+草、灌+草、乔+灌、乔+乔等5个。根据应用频度、栽植数量、生态适应性、用途分为5类,其中基调树种5种,骨干树种15种,常规树种71种,试用树种10种,特用树种12种。In order to analyze and evaluate the current situation of greening tree species in Wuwei,the composition,application frequency,life form,flowering characteristics,ornamental characteristics,ecological adaptability and application form of greening tree species were investigated in typical greening areas of Wuwei.The results showed that there were 113 greening tree species(including varietas,forms and varieties)in the built-up area of Wuwei,there are 18 evergreen tree species and 95 deciduous tree species;48 kinds of trees,25 kinds of small trees,42 kinds of shrubs and 3 kinds of vines;50 species of flowering trees,28 species of foliage trees,15 species of fruit trees and 6 species of branch trees;78 tree species fully adapted to local climatic conditions,25 species basically adapted,and 10 species poorly adapted.There were 6 planting modes,including isolated planting,row planting,opposite planting,cluster planting,cluster planting and group planting.There were 5 configuration modes,including arbor+shrub+grass,arbor+grass,shrub+grass,arbor+shrub and arbor+arbor.There were 6 planting modes,including isolated planting,row planting,opposite planting,cluster planting,cluster planting and group planting.There were 5 configuration modes,including arbor+shrub+grass,arbor+grass,shrub+grass,arbor+shrub and arbor+arbor.According to the application frequency,planting quantity,ecological adaptability and use,the optimization strategies were divided into 5 categories,including 5 basic-tone tree species,15 framework tree species,71 common tree species,10 trial tree species and 12 technological tree species.
