摘要
城市公园绿地是城市园林绿地系统的主体,是集中体现城市植物多样性的场所,研究其植物多样性可为城市生物多样性保护提供基础。以山西太原市17个综合公园为研究对象,从植物应用的重要值、Margalef丰富度、Shannon-Wiener多样性和Pielou均匀度分析其植物多样性,为太原市公园植物多样性保护及公园绿地建设提供参考。研究表明太原市综合公园的植物种类有78科164属285种。植物应用重要值排名前五的种类为大叶黄杨>紫叶小檗>圆柏>国槐>金叶女贞。植物丰富度指数为26.42,乔木层>草本层>灌木层;多样性指数为3.13,乔木层>灌木层;均匀度指数为0.60,乔木层>灌木层。木本植物多样性总体评价较高的公园为汾河公园、玉门河公园和晋祠公园;较低的为映山湖公园、长风商务区大平台景观绿化、南海子公园。
Urban park green space,the main body of the urban landscape system,is a place epitomizing plant diversity in a city.The study of the plant diversity can provide the basis for the protection of urban biodiversity.This paper takes 17 multi-functional parks in Taiyuan City,Shanxi Province,as the research objects to analyze plant diversity in the perspectives of plant application values,Margalef richness,Shannon-Wiener diversity and Pielou uniformity,providing references for the protection of plant diversity and green space construction in the parks of Taiyuan.The results show that there are 285 species of plants that belong to 164 genuses of 78 families in Taiyuan multi-functional parks.The top five species in terms of plant application importance values are Buxus megistophylla > Berberis thunbergii var. atropurpurea > Sabina chinensis > Sophora japonica > Ligustrum vicaryi.The plant richness index is 26.42,with tree layer> grass layer>shrub layer.The diversity index is 3.13,with tree layer>shrub layer.The evenness index is 0.60, with tree layer>shrub layer.The parks with high overall evaluation of woody plant diversity are Fenhe Park,Yumenhe Park and Jinci Park.Those with low evaluation are Yingshanhu Park,Changfeng Business District platform landscape greening,and Nanhaizi Park.
