为了筛选出冬季绿墙应用表现较好的矾根品种，采用AHP层次分析法，对在杭州地区调查收集的21个矾根品种进行冬季绿墙应用综合评价。选取叶观赏价值、冬季生长状况以及绿墙应用潜力等作为评价指标，确定了矾根评价的3级15个指标，建立了综合评价模型。结果表明，21个矾根品种可分为4个等级，其中Ⅰ级（分值≥4.0）5种（草莓旋涡、花毯、力量之源、里奥、上海）、Ⅱ级（分值3.0~4.0）6种（黑曜石、梅子布丁、瑞福安、栖富浪芭、油麦果、玛玛雷都）、Ⅲ级（分值2.0~3.0）7种（朱根砂、黄金斑马、巴黎、芝加哥、日食、冰花、樱桃可乐）、Ⅳ级（分值≤2.0）3种（好莱坞、落日骑士、日出），并参考综合评价及各层次评价结果，结合矾根的观赏特性，推荐了杭州地区冬季绿墙应用中较适宜的矾根品种(草莓旋涡、花毯、力量之源、里奥、上海、黑曜石、梅子布丁、瑞福安、栖富浪芭、油麦果、玛玛雷都)。

In order to screen out the varieties of Heuchera micrantha with good performance in winter green wall application，this paper proposed a comprehensive evaluation model by AHP to evaluate the green wall ap plication of 21 varieties of Heuchera micrantha collected in Hangzhou area in winter.Leaf ornamental value， winter growth status and green wall application potential were selected to define 15 evaluation indexes in 3 grades to build the model.The results showed that，the first grade(≥4.0 scores) included 5 kinds of H.mi crantha(H.micrantha Strawberry Swirls，H.micrantha Tapestry，H.micrantha Solar Power，H.micrantha Ｒio，H.micrantha Shanghai) ，6 kinds in the second grade(3.0—4.0 scores) (H.micrantha Midnight Ｒuffles，H.mi crantha Plum Pudding，H.micrantha Ｒave On，H.micrantha Peach Flambe，H.micrantha Lime Ｒuffles，H.mi crantha Marmalade) ，7 kinds in the third grade(2.0—3.0 scores) (H.micrantha Cinnabar Silver，H.micrantha Gold Zebra，H． micrantha Paris，H.micrantha Gotham，H.micrantha Solar Eclipse，H.micrantha Cracked Ice， H.micrantha Cherry Cola) and 3 kinds in the fourth grade(≤2.0 scores) (H.micrantha Hollywood，H.micran tha Sunset Ｒidge，H． micrantha Sunrise Falls) ． According to the comprehensive evaluation result and evaluation results of each level，combined with the ornamental characteristics of H.micrantha，H.micrantha Strawberry Swirls，H.micrantha Tapestry，H.micrantha Solar Power，H.micrantha Ｒio，H.micrantha Shanghai，H.micrantha Midnight Ｒuffles，H.micrantha Plum Pudding，H.micrantha Ｒave On，H.micrantha Peach Flambe，H.micrantha Lime Ｒuffles，H.micrantha Marmalade，are recommended in the application of green wall in winter．
