黄顶菊(Flaveria bidentis)原产南美洲,2001年在我国河北省衡水湖首次发现,短时间内形成优势种群,并快速向周边省、市蔓延,成为一种危害性极大的新外来入侵植物,对当地生物多样性和粮食生产构成了潜在威胁.2003年首次在山东省临清市发现,为掌握黄顶菊的生物学特性、查清其在山东的发生现状和分布范围,防止进一步扩散蔓延,开展了黄顶菊普查工作.经普查发现,黄顶菊在山东省主要分布在聊城、德州两个地市,危害面积459.03 hm2,目前属于局部零星发生.%Flaveria bidentis, native to South America, is a newly established invasive plant species in China .Since firestly reported in Hengshui lake in Heibei province in 2001,it has quickly become a dominant population in some areas, and has rapidly spreaded to many counties. The invasive species has posed a potential threat to biodiversity and agricultural production in the infested locations. In Shandong province, it has been first discovered in Linqing county in 2006. This study was carried out to thoroughly investigate biological characteristics and occurrence status of Flaveria bidentis in Shandong. According to the survey, Flaveria bidentis was only occured in Liaocheng and Dezhou, endanger area 459.03 hectare, and currently blong to the local occurrence.
