摘　　要：以梅州地区55株野生钟花樱的观赏性综合评价为例,采用Delphi法确定钟花樱各评价因子的权重,运用灰色关联分析法对野生钟花樱的观赏性进行评价。通过计算各单株的加权关联度值r,对r进行排序;再根据有序关联度值r,运用有序样品聚类法,将55株野生钟花樱植株分成4个等级;最后用方差分析对分级结果进行差异性显著性检验,检验结果表明分级结果合理可行。该评价模式可为植物观赏性综合评价提供参考。Take the ornamental characteristic comprehensive evaluation of 55 strains of wild Cerasus campanulata in Meizhou area as an example,the weight of each evaluation factor was determined by Delphi method,the grey correlation analysis method was used to evaluate the ornamental characteristic of wild Cerasus campanulata. Through calculating the weighted correlation degree value r of each individual,ranking r. Then,according to the ordered correlation degree r,the 55 strains of wild Cerasus campanulata were divided into four grades by using the ordered sample clustering method. Finally,variance analysis is used to test the difference of classification result. The test result show that the classification results were reasonable and feasible. The evaluation model can provide a reference for the comprehensive evaluation of plant ornamental characteristic.
