摘　　要：为了充分发掘广东石门台国家级自然保护区野生木本观赏植物资源,利用层次分析法,对保护区自然分布的102种野生观赏木本植物的观赏价值、开发潜力、生物学特性等进行综合评价。综合评价模型由观赏价值、资源开发潜力、生物学特性和应用价值四大约束因素,共17个指标因子构成。结果表明:在一级指标中,观赏价值所占权重最大,表示观赏价值在综合评价中较为重要;在二级指标中,花果色彩、经济价值、生态习性、芳香性等因素对评价结果影响较大。根据综合评分的等级划分,乔木组有15种(南山茶、观光木、毛桃木莲、蓝树、金叶含笑、伯乐树、香港四照花、假地枫皮、头状四照花、厚叶厚皮香、广东含笑、厚叶冬青、桂南木莲、木竹子、钟花樱桃),灌木组有7种(桃金娘、黄花倒水莲、南岭小檗、红花八角、马银花、猴头杜鹃和灯笼树)植物的综合评价为Ⅰ级,此类植物在观赏价值、资源开发潜力和生物学特性方面都具有明显优势,具有较强的开发前景。研究结果可为合理开发木本观赏植物资源提供决策依据。To fully explore the wild woody ornamental plant resources in Guangdong Shimendai National Nature Reserve,a hier-archical analysis method was used to comprehensively evaluate the ornamental value,development potential,and biological characteristics of 102 wild ornamental woody species naturally distributed in the reserve.The comprehensive evaluation model consists of 17 indicators for the four ornamental value constraints:resource development potential,biological characteristics,and application value.The results showed that among the primary indicators,the ornament value accounted for the highest weight,which indicated that the ornamental value was more important in the comprehensive evaluation;among the secondary indicators,the color of flowers and fruits,economic value,ecological habit,and aroma had a better impact on the evaluation results.Ac-cording to the graded classification of the comprehensive score,there are 15 species in the tree group(Camellia semiserrata,Tsoongiodendron ocorum,Manglietia kwangtungensis,Wrightia laevis,Michelia foveolata,Bretschneidera sinensis,Cornus hongkongensis,Illicium jiadifengpi,Cornus capitata,Ternstroemia kwangtungensis,Michelia guangdongensis,Ilex elmerrilliana,Manglietia conifera,Garcinia multiflora,Cerasus campanulata)and seven species in the shrub group(Rhodomyrtus tomentosa,Polygala fallax,Berberis impedita Illicium dunnianum,Rhododendron ovatum,Rhododendron simiarum,Enkianthus chinensis).The comprehensive evaluation of the plants was Grade I.Such plants have advantages in ornamental value,resource development potential,and biological characteristics and have strong development prospects.The results of this study can provide a basis for decision-making regarding the rational development of woody ornamental plant resources.
