摘　　要：目的:全面调查德夯风景名胜区野生观赏植物资源物种组成,从生物学特性、观赏特性和利用潜力3个方面对野生观赏植物资源进行评价。方法:采用野外调查、标本采集鉴定及文献查阅方法,结合AHP层次分析法和熵权法,对该区野生观赏植物资源进行系统分析与评价。结果:该区共有野生观赏植物114科285属422种,其中含种数10种以上的优势科有蔷薇科、百合科、菊科、豆科、茜草科和忍冬科6科;含种数4种以上的优势属有冬青属(Ilex)、荚蒾属(Viburnum)、珍珠菜属(Lysimachia)、卷柏属(Selaginella)、蓼属(Polygonum)、榕属(Ficus)和山茶属(Camellia)7属;生活习性以木本为主;观赏部位以观花植物居多,园林用途中以独赏植物类占明显优势。根据评价值将野生观赏植物划分了5个等级,其中评价值>8.0观赏利用价值最高的I级有75种、评价值>7.0的II级有44种。结论:该区野生观赏植物资源丰富,但利用程度较低,应注重有效保护和合理开发。Objective:To comprehensively investigate the species composition of wild ornamental plant resources in Dehang Scenic Spot,and to evaluate wild ornamental plant resources from three aspects:biological characteristics,ornamental characteristics and utilization potential.Methods:The wild ornamental plant resources in this area were systematically analyzed and evaluated by field investigation,specimen collection and identification,literature review,AHP analytic hierarchy process and entropy weight method.Results:There were 422 species of wild ornamental plants in 285 genera and 114 families,including 6 families with more than 10 species of Rosaceae,Liliaceae,Asteraceae,Fabaceae,Rubiaceae and Caprifoliaceae.The dominant genera with more than 4 species were 7 genera of Ilex,Viburnum,Lysimachia,Selaginella,Polygonum,Ficus and Camellia.The living habits were mainly xylophyta.Ornamental parts were mostly flowering plants.And in garden use,exclusive appreciation plants were obviously dominant.Wild ornamental plants were divided into 5 grades according to evaluation value,of which 75 species were grade I with the highest ornamental value>8.0,and 44 species were grade II with the highest ornamental value>7.0.Conclusion:The wild ornamental planttion and rational development should be emphasized.
