摘要
通过对浙江景宁望东垟、大仰湖自然保护区外来入侵植物调查与监测,研究发现保护区内及周边区域外来入侵植物共有5科13属13种,其中菊科最多有8属8种,占61.54%,多数种在保护区管理场所驻地及社区周边区域呈零星分布,外来植物入侵及影响程度与人为干扰程度密切相关。结果表明:人为干扰是外来植物入侵的主要因素;外来入侵植物数量、分布区域及发生面积等在保护区不同功能区影响程度差异明显;通过严格控制保护区人员进出等措施,加强自然保护区管理是防控外来植物入侵的有效途径,可为加强区域防控外来植物入侵、保护生态环境及提升生态系统功能等方面的研究提供借鉴。
Through the investigation and monitoring of alien invasive plants in Wangdonglong and Dayanghu nature reserves in Jingning,Zhejiang Province.It is found that there are 13 species of alien invasive plants in 5 families,13 genera in the reserve and surrounding areas,of which 8 genera and 8 species of Compositae are the most,accounting for 61.54%.Most species were sporadically distributed in the management site of the reserve and the surrounding areas of the community.The invasion and impact of alien plants were closely related to the degree of human interference.The results showed that human disturbance was the main factor of alien plant invasion;the number,distribution area and occurrence area of alien invasive plants were significantly different in different functional areas of the reserve;strengthening the management of nature reserves by strictly controlling the entry and exit of personnel in nature reserves was an effective way to prevent and control alien plant invasion,and provides reference for strengthening the research on regional prevention and control of alien plant invasion,protecting ecological environment and improving ecosystem function.
