哈密市木本园林植物多样性

为指导哈密市园林景观植物合理搭配,以哈密市的木本园林植物为研究对象,对其物种组成、生活型以及物种来源等进行了分析研究。结果表明:哈密市木本园林植物共35科66属168种,物科属较丰富,种相对匮乏;优势科为蔷薇科、杨柳科、木樨科等;生活型组成中乔木种类灌木木质藤本;引进植物种类与乡土植物的种类比例约为2∶1。未来研究区景观规划和管理中建议根据当地立地条件和特色景观要求,将乡土观赏植物作为骨干,增加其种类和灌木比例。此外,通过适当改造景观结构,以保持较高的物种多样性,改善生态功能。

Plant Diversity of Woody Landscape Plants in Hami City

In order to better understand the plant community characteristics of the Hami city,the woody landscape plants were studied and the species composition,life form and species source of the plants were analyzed.The results showed that a total of 35 families,66 genera and 168 species were founded in the study area;the dominant families were Rosaceae,Salicaceae,Osmanthus,etc;the species of arbor > shrub > woody vines;the ratio of introductionspecies and native species is about 2∶1.Taking into account the local conditions and characteristics under landscape planning and management of the study area in the future,taking local ornamental plants as the backbone,increasing its' varieties and shrub proportion should be a good choice.Furthermore,it would be better to maintain higher species diversity to improve the ecological functions by appropriately transforming the landscapes' structure.
