Comprehensive Evaluation of Willow Ornamental Value Based on Analytic Hierarchy Process
摘要
Abstract
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(Fl),leaf length(F3),ground diameter(F2)and leaf width(F4).The weights of F5 and F6 were 0.478 2 and 0.238 8,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 4.500 0),namely LS-9,HGLC-18,DPC-1,LS-14,SLC-1 and SLC-2.There are 22 clones of grade Ⅱ(4.000 0-4.500 0)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.关键词
