| 中文摘要: |
| 采用样线、样方和踏查等方法，对纳板河流域国家级自然保护区内及周边区域外来入侵植物进行监测。结果表明，纳板河流域国家级自然保护区内及周边区域外来入侵植物有37科88属136种，物种数量稳定，分布范围呈扩大趋势，紫茎泽兰、藿香蓟分布最广，在7条样线和173个样方中均有分布，肿柄菊、阔叶丰花草分布范围扩散加剧，并以人为和无意引入两种方式传播，存在对保护区生物多样性造成影响的隐患。藉此，提出提高认识，建立外来物种风险评估机制，及时掌握外来入侵物种的动态等措施与建议。 |
| 英文摘要: |
| The invasive alien plants in and around Nabanhe National Nature Reserve were monitored by means of line transect, quadrat and field survey. The results showed that 136 species of alien invasive plants belonging to 88 genera and 37 families were found. The number of species was stable and the distribution tended to expand. Ageratina adenophora and Ageratum conyzoides were most widely distributed in 7 line transects and 173 quadrats, while the distribution range of Tithonia diversifolia and Borreria latifolia was spread by artificial and unintentional introduction, resulting in hidden dangers to biodiversity in the reserve. This paper put forward some suggestions, such as raising awareness, establishing the risk assessment mechanism of alien species, and mastering the dynamics of invasive alien species in time. |
