摘要
组织8位林业专业技术员依据5分制评分标准对梅州地区野生刨花润楠(Machilus pauhoi)的9个观赏评价指标进行评分记录,在层次分析法基础上运用熵技术对权系数进行修正并进行评价分析。评价结果表明:(1)叶片性状的权重值为83.33%,明显高于其他性状;(2)熵技术修正后各性状不同观赏评价因子的权重值排序为:叶大小(39.36%)>叶形(26.48%)>叶色(8.55%)>冠形(8.11%)>株形(7.73%)>叶密集度(3.39%)>耐修剪性(3.22%)>色叶期长短(1.94%)>生长势(1.22%);(3)熵技术修正后25株刨花润楠不同单株分为4个等级:Ⅰ级(4.0≤A≤5.0)观赏价值高,共计2个单株;Ⅱ级(3.6≤A<4.0)观赏价值较高,共计8个单株;Ⅲ级(3.0≤A<3.6)观赏价值中等,共计8个单株;Ⅳ级(0<A<3.0)观赏价值低,共计7个单株。观赏价值高的单株编号分别为:2012-01、2015-24。
The nine ornamental evaluation scores of wild Machilus pauhoi were graded through the organization of eight forestry professional technicians based on five-mark standards and evaluated with Analytic Hierarchy Process in Meizhou. Based on the Analytic Hierarchy Process, the weight coefficient was modified and evaluated by the entropy technology. There were three evaluation results were listed as follows： （1） The leaf traits weight was 83.33% which was higher than other traits; （2） After modification with entropy technique, the order for leaf traits weight in different evaluation factors was leaf size（39.36%） 〉 leaf shape（26.48%） 〉 leaf color （8.55%） 〉 crown types（8.11%） 〉 plant type（7.73%） 〉 leaf density（3.39%） 〉 trim degree（3.22%） 〉 color leaf stage（1.94%） 〉 growth vigor（1.22%）; （3） According to the comprehensive evaluation value which modified by entropy technology, 25 different wild M. pauhoi were divided into 4 grades. Level I （ 4.0 ≤ A ≤ 5.0 ） type of higher ornamental value, totally 2; Level Ⅱ （ 3.6 ≤ A 〈 4.0 ） type of high ornamental value, totally 8; Level Ⅲ（ 3.0 ≤ A 〈 3.6 ） type of moderate ornamental value, totally 8; Level IV （ 0 〈 A 〈 3.0 ） type of low ornamental value, totally 7. Type of higher ornamental value was 2012-01, 2015-24 respectively.
