    摘要:

    【目的】近年来,湖北省外来入侵植物数目和种类都呈现上升趋势,但该地区外来入侵植物编目的研究相对滞后,本研究试图填补这项空白,为湖北省外来入侵植物的防治和生态环境保护提供比较全面和准确的数据。【方法】通过查阅文献资料和个人观察,初步确定湖北省外来入侵植物的种类,再根据相关文献和实际野外调查排除不符合外来入侵植物定义的物种,最后确定湖北省外来入侵植物的原产地、生活型、引入途径等。【结果】湖北省外来入侵植物共有145种,隶属于41科,以菊科、豆科、苋科、茄科为主。原产地有8种来源,大部分外来入侵物种原产于北美洲(85种;占全部外来入侵物种的35.6%)。生活型以草本植物为主(134种;占全部外来入侵物种的75.3%)。引入途径有意引入、无意引入、自然传入,占比分别为56.0%、36.7%、7.3%。【结论】研究结果可用于湖北省外来入侵植物的防治,但是为了保证数据的准确性,应定期对湖北省外来入侵植物名录进行更新,以反映实际情况。

    Abstract:

    【Aim】 In recent years, invasive plant diversity and abundance have increased remarkably in Hubei Province, China. Currently, an up-to-date catalogue of invasive plant species in the area is not available and this study attempts to fill this gap, to provide comprehensive, collated data, which could be used towards efforts to control invasive species. 【Method】 Through literature review and scientific observations, the invasive plants in Hubei Province were identified to species level. Based on the relevant literature and actual field investigations, species that did not fit the definition of invasive plants were excluded. Finally, the origins, life forms, and introduction routes of the invasive plants in Hubei Province were determined. 【Result】 A total of 145 invasive plant species were recorded in Hubei Province, belonging to 41 families, mainly Asteraceae, Fabaceae, Amaranthaceae, and Solanaceae. These species originated from eight regions. Most invasive species were native to North America (85 species; 35.6% of recorded invasive species). Life form analysis indicated that herbs were the most common invasive plants (134 species, 75.3% of the recorded invasive species). With respect to the introduction route, unintentional path accounted for 56.0% of introductions, while intentional introduction and naturalization accounted for 36.7% and 7.3%, respectively. 【Conclusion】 The results of this study can help with the control of invasive plant species in Hubei Province. However, to maintain its relevance, it should be updated periodically to reflect current scientific findings.
