摘　　要：通过综合评价柳树无性系观赏性状及生长状况,筛选观赏性强的柳树优良无性系种质资源。选择139个柳树无性系研究对象,测定株高、地径、叶长、叶宽,邀请林业及园林相关领域专家对枝条红艳程度和垂直度打分;基于层次分析法(AHP)构建评价层次结构模型,设置柳树观赏价值评判目标层,树木生长、叶片和外观等3个准则层,在此基础上设置6个因子层,确定各指标权重;对各指标分别赋分,根据综合评分进行观赏性排序,进而评价139个柳树无性系观赏及生长情况。结果表明:因子层各指标对于目标层权重由高到低依次为红艳程度(F5)、垂直度(F6)、株高(F1)、叶长(F3)、地径(F2)和叶宽(F4),F5和F6权重分别为0.4782和0.2388,为主要指标。各无性系形态因子均存在一定差异,观赏价值极高的Ⅰ级(综合得分大于4.5000分)共6个无性系,分别为LS-9、HGLC-18、DPC-1、LS-14、SLC-1和SLC-2;观赏价值高的Ⅱ级(4.0000~4.5000分),共22个无性系。基于层次分析法构建了吉林地区具有代表性的柳树无性系观赏价值层次结构模型,选出的优良无性系柳树观赏价值高,可用于园林绿化及推广栽培。The ornamental characters and growth status of willow clones were evaluated comprehensively in order to select the germplasm resources of willow clones with high ornamental value.A total of 139 one-year-old willow cuttings were selected as the research objects to measure their plant height,ground diameter,leaf length and leaf width,and then experts in forestry and landscape related fields were invited to score the redness and perpendicularity of the plants.An evaluation hierarchical structure model was built based on analytic hierarchy process(AHP),and the evaluation target layer of willow ornamental value were set up,and three criterion layers were set up,namely tree growth,leaf and appearance.Six factor layers were set up to determine the weight value of each index,each index was assigned a score,and the ornamental level was ranked according to the comprehensive score,and then the ornamental and growth situation of 139 willow clones was evaluated.The results show that the weight of each index in the factor layer for the target layer from high to low is redness(F5),verticality(F6),plant height(F1),leaf length(F3),ground diameter(F2)and leaf width(F4).The weights of F5 and F6 were 0.4782 and 0.2388,respectively,which were the main indicators.There were some differences in morphological factors among all clones.There are 6 clones in grade I with extremely high ornamental value(comprehensive score greater than 4.5000),namely LS-9,HGLC-18,DPC-1,LS-14,SLC-1 and SLC-2.There are 22 clones of gradeⅡ(4.0000-4.5000)with high ornamental value.Based on the analytic hierarchy process(AHP),a representative ornamental value hierarchy model of willow clones in Jilin region was established.The selected clones with high ornamental value could be used for afforestation and promoting cultivation.
