摘要:
[目的]通过对安徽省郎溪地区农村庭院植物组成与多样性的研究,为优化庭院植物群落结构提供科学依据。[方法]以安徽省郎溪县10个村庄的369个农村庭院群落为研究对象,对庭院分布的栽培植物进行了调查记录。[结果]该地区农村庭院共有171种植物,隶属于66科139属,其中以蔷薇科、十字花科、木犀科等含有较多的种类。多度、频度和重要值均表明,香樟和桂花分别在乔木层和灌木层具有较大优势。1号村庄和7号村庄的多样性指数分别在乔木层和灌木层优于其它村庄,但该地区农村庭院的物种多样性水平整体不高。观赏植物和食用植物在该地区农村庭院中占有较大的比重,分别为58.48%和33.33%。[结论]郎溪县农村庭院存在植物群落结构不合理,物种多样性低,部分物种过度使用,乡土树种利用率低等问题;提升村民生态环境优化意识是改善该区域庭院群落现状的关键。

Abstract:
[Objective] In order to provide scientific basis for optimization of plant community in rural homegardens(HG), we took Langxi County of Anhui Province as a study case on species composition and diversity.[Methods] Cultivated plants of 369 HG were surveyed in ten villages in Langxi County of Anhui Province.[Results] There were 171 species belonging to 66 families and 139 genera in this area. Among them, Rosaceae, Cruciferae and Oleaceae contained more species than the others. Based on the abundance, frequency and importance value, Cinnamomum camphora and Osmanthus fragrans were the most important species in arbor layer and shrub layer, respectively. Generally, the level of species diversity was lower in each HG; however, the index of species diversity of No.1 village and No.7 village were better than that of the others in arbor layer and shrub layer, respectively. Species of ornamental plants and food plants accounted for 58.48% and 33.33%.[Conclusion] There were some problems in the rural HG of Langxi County, such as unhealthy structure of plant community, lower species diversity in each HG, overuse of some species, low utilization of native species etc. To improve the present vegetation of HG, it is key to develop the consciousness of farmers about optimization of ecological environment.
