浙江入侵新记录种薇甘菊发生现状及危害预测

A new Invasive Genus and Species of Mikania micrantha in Zhejiang Province

摘要

摘要: 2021年，在浙江省温州市瓯海区发现假泽兰属MikaniaWilld.薇甘菊MikaniamicranthaKunth野外种群，此发现为浙江省菊科Asteraceae归化新记录属、种。在给出该植物的形态特征、实地拍摄图片和凭证标本（温州大学标本馆-WZU）的基础上，对薇甘菊在温州地区野外入侵现状和其生境植物多样性进行调查。结果表明，薇甘菊在湿地水岸边和山地路边均有较强的适应性，已形成了初步扩散的趋势。提出了加强生物检疫，外来入侵植物的巡查，做到早发现早清除的防控建议。本次发现为我国外来入侵植物的防控、生物多样性和生态环境的保护提供了重要信息，并且薇甘菊在浙江的发现更新了其在我国入侵分布的记录，浙江成为该种入侵分布的中国最北界。
