外来物种入侵对林业生态安全的影响及防控
摘 要
外来物种入侵已成为全球性的生态问题，对林业生态安全构成了严重威胁。外来物种通过竞争、捕食、寄生等方式，破坏本地生态系统的平衡，引发病虫害的爆发，影响林业生产的效益，甚至威胁到生物多样性的保护。本研究以外来物种入侵对林业生态安全的影响及防控为研究对象，首先概述了外来物种入侵的基本概念、林业生态安全理论以及生态系统稳定性与外来物种入侵的关系。在此基础上，深入分析了外来物种入侵对林业生态安全的破坏作用，包括破坏生态平衡、引发病虫害、影响林业生产和威胁生物多样性等方面。同时，本研究还揭示了外来物种入侵防控中存在的问题，如法律法规不完善、防控技术不足、公众意识薄弱以及国际合作与交流不足等。针对这些问题，本研究提出了完善法律法规与监管机制、提升防控技术研发与应用能力、提高公众意识与参与度以及加强国际合作与交流等针对性的防控对策。

THE INFLUENCE OF ALIEN SPECIES INVASION ON FORESTRY ECOLOGICAL SECURITY AND ITS PREVENTION AND CONTROL
ABSTRACT
The invasion of alien species has become a global ecological problem and poses a serious threat to the forestry ecological security. Through competition, predation and parasitism, alien species destroy the balance of the local ecosystem, cause the outbreak of diseases and insect pests, affect the benefits of forestry production, and even threaten the protection of biodiversity. In this study, the impact of alien species invasion on forestry ecological security and the prevention and control are studied, and first, the basic concept of alien species invasion, the theory of forestry ecological security and the relationship between ecosystem stability and alien species invasion are summarized. On this basis, the damage of alien species invasion on forestry ecological security, including destroying ecological balance, causing diseases and insect pests, affecting forestry production and threatening biodiversity. At the same time, this study also revealed the problems in the invasion prevention and control of alien species, such as imperfect laws and regulations, insufficient prevention and control technology, weak public awareness and insufficient international cooperation and communication. In view of these problems, this study puts forward targeted prevention and control countermeasures, such as improving laws, regulations and regulatory mechanisms, enhancing the research and development and application ability of prevention and control technologies, enhancing public awareness and participation, and strengthening international cooperation and exchanges.
