摘　　要：以8种在长江流域及以南地区自然越冬的宿根花卉为目标物种,采用层次分析法建立了评价体系及评价标准,评价了其在北京背风向阳环境条件下的观赏性及生长适应性。结果表明:草原毛叶蜜糖草无法自然越冬,花叶紫娇花越冬率约60%,其余6种(紫娇花、紫叶毛地黄钓钟柳、裂叶锥托泽兰、银边花菖蒲、雄黄兰、樱桃鼠尾草)在北京背风向阳环境条件下均可以露地无保护越冬,且观赏性较强,具有较高的应用推广价值。In this study,8 perennial flowers that can overwinter naturally in Yangtze River Basin and the south were selected as the objective species.The evaluation system and evaluation criteria were established by using analytic hierarchy process(AHP)to estimate their ornamental value and growth adaptability under the environmental conditions of leeward and sunward in Beijing.The results showed that Melinis nerviglumis‘Savannah’can't live through the winter in Beijing even though planted on the south side of the building;the rate of overwintering of Tulbaghia violacea‘Variegata’was about 60%,and the other 6 species(Tulbaghia violacea,Penstemon digitalis‘Husker Red’,Conoclinium dissectum‘Blue Mist’,Iris ensata‘Variegatum’,Crocosmia×crocosmiiflora and Salvia greggii)could overwinter without any protection under the microclimate outdoor environment which was lee wind with a sunny exposure in Beijing.They are worthy to promote application in Beijing because of the ornamental value and adaptability.
