摘要:
【目的】近几年,内蒙古外来入侵植物种类日趋增长、对当地物种和环境的危害逐渐加大,相关研究相对薄弱。了解内蒙古外来入侵植物种类组成,分析其生活型、原产地、引进途径,能够为今后内蒙古外来入侵植物的管理与防治工作提供基础资料。【方法】通过野外实地考察,查阅相关文献与数据库,对内蒙古外来入侵植物进行分类统计分析。【结果】内蒙古外来入侵植物共有94种,隶属于24科65属,其中,种数超过10种的有3科,分别为菊科(22种,占总种数的23.4%)、苋科(11种,占总种数的11.7%)和禾本科(11种,占总种数的11.7%);生活型分析发现,一年生草本最多(68种),占总种数的72.3%,二年生草本(25种)与多年生草本(18种)分别占总种数的26.6%和19.1%,乔木、灌木较少;原产地来源最多的是北美洲(44种),占总种数的46.8%,最少的是非洲(8种),仅占总种数的8.5%;引进途径中,有意引进和无意引进分别占总种数的48.9%和51.1%。【结论】内蒙古外来入侵植物种类较多、涵盖科广泛,以菊科、苋科和禾本科为主;来源广、无意引进趋势增强。为了防止其对本地生态、经济、人畜健康等方面的危害,应及时展开外来入侵植物风险评估、有效防除等工作。

Species investigation and related analysis of the alien invasive plants in Inner Mongolia
Abstract:
【Aim】In recent years, the taxon and quantity of alien invasive plants have been increasing in Inner Mongolia result in increasing serious harm to the local organisms and environment. Instead, the related research are very poor. Understanding the species composition of alien invasive plants and analyzing their life forms, origin and introduction route, which provides basic data for the management and prevention of alien invasive plants in Inner Mongolia. 【Method】Based on field investigation, literature and database collation, the alien invasive plants were classified and statistically analyzed in Inner Mongolia. 【Result】There were 94 alien species in Inner Mongolia, belonging to 65 genera and 24 families. Among them, Asteraceae (22 species), Amaranaceae (11 species) and Gramineae (11 species) were more than 10 species, accounting for 23.4%, 11.7% and 11.7% of the total species, respectively. According to the analysis of life forms, annual herbs, biennial herbs and perennial herbs accounted for 72.3%, 26.6% and 19.1% of the total species, respectively, while few arbors and shrubs were found. In Inner Mongolia, the most invasive alien plants originated from North America (44 species, 46.8%) and the least originated from Africa (8 species, 8.5%). For introduction route, intentional introduction and unintentional introduction accounted for 48.9% and 51.1% of the total species, respectively. 【Conclusion】It was found that there were many alien invasive plants in Inner Mongolia, covering a wide range of families, mainly Asteraceae, Amaranthaceae and Gramineae. Their sources were wide and the tendency of unintentional introduction was increasing. In order to prevent their harm to local ecology, economy, human and animal health, it was important to take risk assessment and effective control in time.
