摘要:
文章以野鸦椿(Euscaphis japonica)为例 , 采用层次熵灰色关联法 , 对梅州地区调查发现的 33 株自然生长的野鸦椿植株的观赏价值进行综合评价。首先根据林业专业人员给出的各评价指标的重要性 值 , 用层次分析法确定各指标权重 , 然后用熵值法进行修正 , 在修正的权重基础上 , 对野鸦椿进行灰色关 联综合评价 , 并根据加权关联度 R 的大小对 33 株野鸦椿的观赏性进行量化排序与分级。 33 株野鸦椿分成 4 个等级 , 其中观赏价值高的一级单株有 1 株 (R=0.868), 是 32 号树 ( 苍子下 3 号 );观赏价值较高的二级 单株有 1 株 (R=0.681), 是 12 号树 ( 樟坑 12 号 );观赏价值为三级的单株有 7 株 (0.402 ≤ R < 0.681);其 余 24 株为四级单株 (0 < R < 0.402)。且所分等级差异性通过了显著性检验 , 说明分级结果合理可行。

Abstract:
In order to explore the scientific plant ornamental evaluation method, taking Euscaphis japonica as an example, the grey correlation method was adopted to evaluate the ornamental value of 33 naturally growing strains of E. japonica in Meizhou area. Firstly, according to the importance value of each evaluation index given by forestry professionals, the weight of each index was determined by analytic hierarchy process, and then was modified by entropy method. On the basis of the corrected weight, the grey relational method was used to comprehensively evaluate the E. japonica. Based on the size of the weighted correlation degree R, the 33 strains of E. japonica appreciation was quantitatively ranked and classified. The results showed that 33 strains of E. japonica were divided into four grades, among which 1 plant with high ornamental value ( 0.868) R = was NO. 32 (Cangzixia NO.3), and 1 plant in the second-grade ornamental value ( 0.681) R = was NO. 12 (Zhangkeng NO.12). There were 7 plants with the ornamental value of grade three(0.402 ≤ R < 0.681), and the remaining 24plants were in the four-grade (0 < R < 0.402). In addition, the difference in grade passed significance test, which showed that the classification results were reasonable and feasible.
