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.
