摘　　要：树种对区域自然地理和生态环境的适宜性是园林绿化树种选择和应用的基础。为给太原市的园林绿化树种选择与应用提供依据,从树种的本地生长发育状况、生态要求、抗逆性和抗污染性4方面构建评价指标体系,采用层次分析与系统聚类分析相结合的方法,对太原市340个现有园林绿化树种进行生态适宜性评价和分类,建立分类体系,明确类型特征。按树种生态要求,分为中性至弱碱性-耐粘重-浅土、中性-轻壤-中土、中性-沙壤-浅土、中性至弱碱性-中壤至轻壤-较深土、耐碱-中壤-深土、弱酸性-轻壤至沙壤-较深土和耐碱-中壤至轻壤-中土树种,共7个类型;按树种抗逆性,分为耐寒-耐旱-耐瘠薄、较耐寒-较耐水湿-较耐荫、不耐寒-较耐旱、较耐寒-较耐旱-较耐瘠薄、不耐寒-不耐旱-不耐瘠薄、不耐寒-不耐旱-较耐水湿和不耐瘠薄-耐水湿-较耐荫树种,共7个类型;按树种生态适宜性分为较耐寒-较耐旱-较耐荫-浅土、耐寒-耐旱-较深土、不耐寒-较耐水湿-较深土、较耐寒-较耐瘠薄-耐荫-中性-中土、较耐寒-不耐荫-不抗污染-中性至弱碱性-深土、不耐寒-不耐旱-不耐瘠薄-轻壤至沙壤-中性-较深土、不耐寒-不耐旱-较耐水湿-轻壤至沙壤-中土和不耐瘠薄-较耐荫-不抗污染-沙壤-较深土树种,共8个类型。Suitability of tree species to regional physical geography and ecological environment is basis for selection and application of landscape tree species.In order to provide reference for selection and application of landscape tree species in Taiyuan city,evaluation index system was builded from local growth condition,ecological requirement,stress resistance and pollution resistance.Ecological suitability of 340 existing landscape tree species in Taiyuan city was evaluated and classified by method of analytic hierarchy process and systematic cluster analysis.Classification system was established,and characteristics of all types were defined.In terms of ecological requirements,tree species could be divided into 7 species including neutral to weak alkaline-heavy soil-shallow soil,neutral-light loam-middle soil,neutral-sandy loam-shallow soil,neutral to weak alkalinemiddle loam to light loam-deeper soil,alkali resistance-middle loam-deep soil,weak acid-light loam to sandy loam-deeper soil and alkali resistance-middle loam to light loam-middle soil.In terms of stress resistance,tree species could be divided into 7 species including cold resistance-drought resistance-barren resistance,relatively cold resistance-relatively waterlogging resistance-relatively shade resistance,frigolabile-relatively drought resistance,relatively cold resistance-relatively drought resistance-relatively barren resistance,frigolabile-siccolabile-not resistant to barren soil,frigolabile-siccolabile-relatively waterlogging resistance and not resistant to barren soil-waterlogging resistance-relatively shade resistance.In terms of ecological suitability,tree species could be divided into 8 species including relatively cold resistance-relatively drought resistancerelatively shade resistance-shallow soil,cold resistance-drought resistance-deeper soil,frigolabile-relatively waterlogging resistance-deeper soil,relatively cold resistance-relatively barren resistance-shade resistanceneutral-middle soil,relatively cold resistance-intolerant of shade-not r
