摘　　要：以海坛岛102种野生灌木为研究对象,采用灰色关联度分析法对其进行了综合评价,根据关联度大小划分了开发利用等级。旨在合理开发利用海坛岛野生灌木资源,为滨海城市的园林绿化材料提供参考。结果表明:1)海坛岛野生灌木资源种类丰富,分布于41科72属102种,桑科Moraceae为优势科,榕属Ficus为优势属;2)海坛岛野生灌木区系地理成分多样,热带成分丰富;3)该类资源适应性强,原生境以海岸林、山坡灌丛为主(59.80%);有63.73%的灌木耐干旱、耐贫瘠,部分耐盐碱(51.96%);灌木的观赏价值较高,在观赏部位、观赏期、观赏色彩指标得分均≥2;4)参评的102种野生灌木中有54种与理想种关联度≥0.7,其中海桐(Pittosporum tobira)、雀梅藤(Sageretia thea)、车桑子(Dodonaea viscosa)、草海桐(Scaevola sericea)、滨柃(Eurya emarginata)、柞木(Xylosma racemosum)、黑面神(Breynia fruticosa)等17种野生灌木综合评价高(关联度≥0.8),可优先应用于园林绿化,并引种推广。This article takes 102 wild shrubs in Haitan Island as the research object,comprehensively evaluates it by the grey correlation analysis method,and divides the development and utilization grade according to the correlation degree.It aims to rationally develop and utilize wild shrub resources on Haitan Island,and provide a reference for the landscaping materials of coastal cities.The results showed that:1)There are abundant wild shrub resources in Haitan Island,distributed in 41 families,72 genera and 102 species,Moraceae in the family is dominant and Ficus is dominant in the genera;2)The wild shrub flora in Haitan Island is diverse in geographical components and rich in tropical elements;3)This kind of resources has strong adaptability,the original habitat is mainly coastal forest and hillside shrub(59.8%),63.73% of the shrubs are drought-resistant,barren-resistant(51.96%),the ornamental value of the shrubs is relatively high,the scores of ornamental position,ornamental period and ornamental color indexes are all≥2;4)Among the 102 wild shrubs evaluated,54 species showed a correlation degree with the ideal species higher than 0.7.Moreover,17 species showed a degree of correlation with the ideal species higher than 0.8,such as Pittosporum tobira,Sageretia thea,Dodonaea viscosa,Scaevola sericea,Eurya emarginata,Xylosma racemosum and Breynia fruticosa,which can be applied to landscape greening as well as introduced and popularized preferentially.
