北京维管植物三十年之变化

植物名称是人类对植物研究与利用等活动的基础。植物名称的变化可能成为不同行业之间交流的障碍, 错误或含混的植物名称可能会造成不便甚至损失。北京作为中国的首都, 在生物多样性保护与生态文明建设的背景下, 对于植物多样性信息变化的管理水平和能力要求更高。及时并准确地更新植物名称的变化及其过程, 对于植物学工作者、园林工作者和与植物相关产业从业者都十分重要。本文基于过去30年间(1992?2021年)北京各类维管植物的名称信息, 记录了自1993年《北京植物志》(1992年修订版)以来的维管植物名称的变化过程: 包括34个新类群、175个新记录、509个新异名, 49个错误鉴定, 以及50个存疑类群。过去30年间, 北京的维管植物发生了很大的变化。本文结果可作为北京维管植物多样性监测和保护的重要参考。
