菏泽曹州牡丹园植物群落多样性研究

Study on plant community diversity of Caozhou Peony Garden in Heze

城市公园是城市绿地系统的重要组成部分,是城市植物多样性集中体现的场所,研究其植物多样性可为城市生物多样性保护、维持城市生态系统平衡提供理论基础。文章以菏泽市曹州牡丹园为研究对象,采用典型样方法,对公园植物群落物种组成及物种多样性进行了调查统计和分析。结果表明:公园共有36科、66属、81种植物,其中乔木43种、灌木21种、草本17种、常绿植物16种、落叶植物65种;优势种明显,优势科为蔷薇科、禾本科、豆科、木犀科等;物种多样性指数均为乔木层>灌木层>地被层,灌木层与地被层物种丰富度较低。

Urban parks are an important part of the urban green space system.They are the places where urban plant diversity is concentrated.Studying its plant diversity can provide a theoretical basis for the protection of urban biodiversity and maintaining the balance of urban ecosystems.The article takes the Caozhou Peony Garden in Heze City as the research object,and uses the typical method to investigate and analyze the species composition and species diversity of park plant communities.The results show that there are 36 families,66 genera and 81 species in the park,including 43 species of trees,21 species of shrubs and 17 species of herbs;16 species of evergreen plants and 65 species of deciduous plants;the dominant species are obvious,and the dominant families are Rosaceae and Wo.Undergraduate,leguminous,Oleaceae,etc.;species diversity index is arbor layer>shrub layer>ground layer;shrub layer and ground layer species richness.
