摘 要:以上海市区放弃管理的江湾机场为例,探讨了城市区域自然植被的物种组成特征.江湾机场植物物种丰富,共有野生维管植物66科176属229种,其中蕨类植物5科5属5种,种子植物61科171属224种,维管植物中82.6%为草本植物,世界广布种占总种数的28.8%.171属种子植物划分为13个分区类型,以温带成分稍占优势。组成复杂,地理成分多样.江湾机场面临二次开发,建议在规划过程中加强小生境保护,并对现存植被进行分级控制,快速建成低成本、高效益的绿地网络.The floristic character of abandoned Jiangwan Airport in Shanghai was analyzed. The flora of vascular plant in the study area consisted of 229 species and varieties, 176 genera and 66 families of which 5 species, 5 genera and 5 families belonged to Ptefidophyta. Among the vascular flora, 82.6 percentage were herbage and 28.8 percentage were Cosmopolitan. According to the geographical distri- bution of seed plants genera, they were divided into 13 types (varieties included). The floristic composition is complex and geographical components are various, meanwhile temperate elements have a little superiority. For Jiangwan Airport is faced with the further exploitation, the key habitats should be conserved and the vegetation also should be managed according to their status to construct a green space system with lower cost and higher value rapidly.
