上海濒危植物现状及保护对策

通过实地网格化调查、标本查阅及历史资料搜集对上海濒危植物现状及保护对策进行了研究,结果表明:上海共有国家重点保护和濒危野生植物23科27属28种,建议上海重点保护的野生植物有54科82属101种。上海原生植物减少、外来植物增多、生物多样性降低等是上海一些原生植物变为濒危的主要原因。今后应建立上海濒危植物保护体系,重点保护上海的植物多样性中心,并尽快立法公布上海地方重点保护野生植物名录;加强植物多样性保护宣传,保护上海的野生植物资源并防范外来植物入侵。

Current Status and Conservation Strategies of Endangered Plants from Shanghai,China

The current status and conservation strategies of endangered plants in Shanghai were studied through field investigation, specimen examination and historical data collection. Results showed that there were 28 species of 27 genera of 23 families, which was national key protected and endangered plants in Shanghai, and 101 species of wild plants, belonging to 82 genera and 54 families, should be protected in Shanghai. Native plants have decreased in recent years, while alien plants have increased. Furthermore, plant diversity has reduced, which helps explain why some native plants have decreased. An endangered plant protection system should be established for Shanghai plants, Moreover, plant diversity centers should be protected in a priority and a list of wild species of key protected plants should be published as soon as possible. Plant diversity publicity should also be enhanced in the future and wild plants of Shanghai should be protected while exotic invasive plants should be prevented.
