关于互花米草在辽宁分布的商榷

Discussion on the distribution of Spartina alterniflora in Liaoning Province

互花米草是我国滨海地带重要入侵植物。辽宁地处黄渤海之滨,是我国滨海地带最北界,确定互花米草在辽宁是否有分布对于制定我国北方地区防控互花米草的策略具有重要意义。经现场调查、标本比对,发现目前在辽宁丹东东港市、大连庄河市、葫芦岛兴城市和龙港区有大米草分布,而无互花米草分布,当地管理部门应采取有效措施铲除大米草。

Spartina alterniflora is an important invasive plant in the coastal area of China. Liaoning is the northernmost boundary of China’s coastal zone,facing the Yellow Sea and Bohai Sea. Whether the S.alterniflora distributes in Liaoning is important to develop strategy of preventing and controlling S. alterniflora in northern China. Through field investigation,specimen comparison,it was proved that S. anglica was distributed in Dandong City,Dalian Zhuanghe City,Huludao Xingcheng City and Longgang District of Liaoning Province,while no S. alterniflora was found. Local management departments should take effective measures to eradicate S. anglica.
