| 虽然城市自生植物的自我繁衍能力有利于营造低维护景观，但可能会对非目标区域的栽培植物景观产生不利影响。调查了南京市21处公园绿地中自生草本植物组成情况，并从种子传播方式角度，探讨了自生植物园林应用策略。共发现自生草本植物56科186属241种。其中，57种入侵植物中风力传播型植物比例最高(45.61%，26种)；184种非入侵性植物中自体传播植物比例最高(42.93%，79种)。建议自体传播型自生植物适用于老旧城区景观改造；动物传播型自生植物适用于动物类群较为丰富的场地，如郊野公园等；风力传播型自生植物适用于工矿区或农村区域。 |

| Abstract: |
| The self-proliferation capability of urban autogenesis plants is conducive to the creation of low-maintenance landscapes; however, it may adversely affect the aesthetic value of cultivated ornamental plant landscape out of the target area. The study surveyed the species composition of autogenesis herbs in 21 parks in Nanjing city, and discussed the landscape application strategies of autogenesis herbs from the perspective of seed dispersal mode. A total of 241 species of 186 genera were found in 56 families of spontaneous herbs in the parks surveyed. Among 57 species of invasive plants, the proportion of wind dispersal plants is the highest, accounting for 45.61% (26 species). Among 184 species of non-invasive plants, the proportion of unassisted dispersal plants is highest, accounting for 42.93% (79 species). According to seed dispersal mode, the study suggests that unassisted dispersal plants are suitable for landscape reconstruction in old urban areas; animal dispersal plants are suitable for areas with abundant animal groups, such as country parks; and wind dispersal plants can be used in the ecological restoration of industrial, mining areas and rural areas. |
