惠州城市公园绿地自生植物调查分析

Investigation and Analysis of Spontaneous Vegetation in the Huizhou Urban Park Greenbelt

自生植物在城市环境中不仅能明显减轻养护管理负担,而且在构建可持续低投入维护的园林植物景观中具有重要地位。以惠州市城市公园为研究对象,采用样方法,对城市公园绿地自生植物进行调查,并深入分析其物种组成特征和群落特点。结果表明:本次研究共调查自生植物121种,隶属于44科105属,以豆科(Fabaceae)、菊科(Compositae)、禾本科(Gramineae)、大戟科(Euphorbiaceae)、莎草科(Cyperaceae)等5个科为优势科;生活型组成十分丰富,其中一年生草本植物最多,共计有41种。植物来源以乡土植物为主,有59种,占48.76%;国内外来植物有51种,占42.15%;国外外来植物有11种,其中入侵植物有7种。在群落多样性方面,不同生境中自生植物群落多样性存在显著差异。

Spontaneous vegetation in the urban environment can not only significantly reduce the burden of maintenance management but also play a vital role in the construction of sustainable low-input maintenance garden plant landscapes.Taking Huizhou City Park as the research object,we used the sampling method to investigate the spontaneous vegetation in the green space of urban parks,and we analyzed their species composition characteristics and community features in depth.The results show that there are 121 species of spontaneous vegetation investigated in this study,belonging to 44 families and 105 genera,with five families as dominant families,including Fabaceae,Compositae,Gramineae,Euphorbiaceae,and Cyperaceae,and the composition of life types is very abundant.The composition of life types is very abundant,among which annual herbaceous plants are the most numerous,totaling 41 species.The plant sources were dominated by native plants,with 59 species,accounting for 48.76%;51 domestic and foreign plant species,accounting for 42.15%;and 11 exotic plant species,including seven species of invasive plants.In terms of community diversity,there were significant differences in the diversity of spontaneous vegetation communities in different biomes.
