摘要
通过检索文献资料,筛选出有关我国自然保护区入侵植物的期刊论文,提取有关数据,从被入侵保护区数量、入侵植物种类等方面进行了分析。结果表明,目前我国公开报道过入侵植物调查的保护区数量极少,仅占2.5%;在69个被入侵的自然保护区中,部分自然保护区入侵植物种类多达115种;共有353种入侵植物,涉及66个科,菊科植物小蓬草出现频率最高,达0.54,其次为一年蓬、鬼针草,出现频率为0.51和0.46;入侵植物以草本居多,占79.3%。因此,应尽快开展和推进自然保护区入侵物种调查,为入侵区域制定相应的防控措施提供指导。
A thorough literature search and review was conducted to determine the species of invasive plants reported in nature reserves in China.Only a few(2.5%)of the nature reserves in China have publicly reported the investigation of invasive plants.Among the 69 invaded nature reserves,there were 353 invasive plant species belonging to 66 families with the highest frequency of 0.54 corresponding to Erigeron canadensis.The majority(79%)of the invasive plants were herbs.Therefore,surveys of invasive species in nature reserves should be carried out and promoted as soon as possible,in order to provide guidance on the formulation of appropriate prevention and control measures.
