摘要
面对外来入侵植物对本土生态系统和生物多样性带来的严重破坏,有效的应对策略至关重要。对唐河县友兰国家湿地公园的外来植物入侵情况进行实地调查,构建了风险评估指标体系并对其进行了风险评估,以期为管控和防治外来植物入侵提供科学的支持。调查结果显示:唐河县友兰湿地公园外来入侵植物共计50种,隶属于21科44属。所占比例最大的三个科分别是菊科(13种)、豆科(6种)、禾本科(4种)。其中草本是最主要的生活型,96%的外来入侵植物为草本。大部分外来入侵植物的风险等级为高风险等级和一般风险等级,占外来入侵植物的76%左右。基于此,提出了防控建议:从源头上控制,监测预警;加强科普宣传,提升公众对生态安全的重视度;科学引种,加强检疫和科学防治。以此可以更有效地减轻外来入侵植物对唐河县友兰国家湿地公园生态系统的负面影响。
Facing the severe damage that invasive alien plants bring to local ecosystems and biodiversity,effective coping strategies are essential.A field investigation was conducted on the invasion of alien plants in the Youlan National Wetland Park in Tanghe County,and a risk assessment index system was established and assessed to provide scientific support for the management and control of invasive plant species.The survey results showed that there are a total of 50 species of invasive alien plants in the Youlan National Wetland Park,belonging to 21 families and 44 genera.The top three families in terms of proportion are Asteraceae(13 species),Leguminosae(6 species),and Poaceae(4 species).Herbs are the dominant life form,with 96% of the invasive alien plants being herbs.The majority of the invasive alien plants are classified as high-risk and general-risk levels,accounting for about 76% of the invasive alien plants.Based on this,prevention and control recommendations are proposed:control from the source,monitoring and early warning;strengthen public science education to raise awareness of ecological security;scientifically introduce species,strengthen quarantine and scientific control.This can more effectively reduce the negative impact of invasive alien plants on the ecosystem of the Youlan National Wetland Park in Tanghe County.
