| 摘要：通过野外调查与样方分析，研究了南京琵琶湖至太平门段明城墙基部文管植物的物种多样性。在100个2 m × 0.5 m样方中，共发现文管植物69种5967株，隶属于66科45属。其中被子植物63科42属66种，共计5588株；蕨类植物3科3属3种，共计379株。在传播方式方面，适应于鸟类传播的植物共23种852株；适应于风力传播的植物共32种3478株；传播媒介不明确的植物共14种1637株。城墙基部文管植物中乡土植物为63种5836株，外来入侵植物共6种131株。在生活型方面，常绿植物有11种，占种类总数的15.94 %；落叶植物有58种，占种类总数的84.06 %。此外，讨论了南京明城墙基部文管植物的经济价值及生态功能，以期为南京城市生物多样性研究与管理提供有价值的基础资料。26198 毕业论文关键词：明城墙；文管植物；资源价值；生物多样性 Study on the persity of vascular plants inhabiting near the base of Nanjing city wall of the Ming Dynasty between Pipa Lake and Taiping Gate Abstract：The persity of vascular plants inhabiting near the base of Nanjing city wall of the Ming Dynasty between Pipa Lake and Taiping Gate has been studied, through field investigation and sample analysis. 69 species in 45 genera of 66 families were found in 100 quadrats along the base of the city wall, each quadrat is 2 m × 0.5 m large. Among them, angiosperms consisted of 66 species in 42 genera and 63 families, with 5588 inpiduals. Ferns consisted of 3species in 3 genera and 3 families, with 379 inpiduals. 852 inpiduals of 23 species were adapted to the primary seed dispersal by birds,3478 inpiduals of 32 species were adapted to the primary dispersal of seeds or spores by wind, but the diaspore dispersal mode of the other 1637 inpiduals of 14 species is still uncertain. 63 species with 5836 inpiduals are native plants, while 6 species with 131 inpiduals are invasive alien plants. 11 species are evergreen, accounting for 15.94 % of the total species; while 58 species are deciduous, accounting for 84.06 % of the total species. Furthermore, both the economic values and the ecological functions of the vascular plants inhabiting near the base of Nanjing city wall are also discussed, in order to provide some substantial data for the research and management of the urban biopersity of Nanjing city.
