怀化市森林、草原、湿地生态系统外来入侵物种调查结果与防控策略

Investigation Results and Control Strategies of Invasive Alien Species in Forest,Grassland and Wetland Ecosystem of Huaihua City

[目的]本研究旨在调查怀化市森林、草原、湿地生态系统中外来入侵物种的现状,为制定有效的防控策略提供基础数据,以保护该地生态安全和生物安全。[方法]通过对怀化市林草湿外来入侵物种进行全面普查,我们初步摸清了外来物种的入侵现状。普查范围覆盖全市,涉及多种生态类型,包括植物、病原微生物、昆虫、无脊椎动物和脊椎动物等。[结果]普查结果显示,怀化市共发现95种外来入侵物种。其中,植物类外来入侵物种有85种,病原微生物1种,昆虫1种,无脊椎动物2种,以及脊椎动物6种。在这些物种中,有21种属于重点管理外来入侵物种,如松材线虫(Bursaphelenchus xylophilus)和加拿大一枝黄花(Solidago canadensis)等。[结论]基于本次普查结果,我们提出了一系列防控对策,包括强化常态化监测、加强重点管理外来入侵物种的防控、科学治理和修复生态环境、充分利用调查成果、保障防控资金投入以及加强外来入侵物种危害性的宣传等。这些对策的实施将有助于减少外来入侵物种对怀化市生态系统的威胁,维护生态安全和生物安全。

[Objective]This study aims to investigate the current status of invasive alien species in the forest,grassland,and wetland ecosystems of Huaihua City,providing fundamental data for developing effective prevention and control strategies to protect the ecological and biological security of the region.[Method]Through a comprehensive survey of invasive alien species in the forests,grasslands,and wetlands of Huaihua City,we have initially ascertained the current status of alien species invasion which co vers the entire city,involving multiple ecological types,including plants,pathogenic microorganisms,insects,invertebrates,and vertebrates.[Result]The survey results show that a total of 95 invasive alien species are discovered in Huaihua City.Among them,there are 85 plant species,1 pathogenic microorganism,1 insect species,2 invertebrate species,and 6 vertebrate species.Among these species,21 are invasive alien species under key management,such as Bursaphelenchus xylophilus(Pine Wood Nematode)and Solidago canadensis(Canada Goldenrod).[Conclusion]Based on the results,we propose a series of prevention and control measures,including strengthening regular monitoring,enhancing the prevention and control of invasive alien species under key management,scientifically managing and restoring the ecological environment,fully utilizing the survey results,ensuring investment in prevention and control funds,and strengthening the promotion of the hazards of invasive alien species.The implementation of these measures will help reduce the threat of invasive alien species to the ecosystem of Huaihua City and maintain ecological and biological security.
