摘 要
本文旨在全面探讨外来物种入侵对林业生态的影响及其防控策略。首先概述了外来物种的定义、分类标准及入侵途径，明确了研究背景。接着，阐述了预防外来物种入侵在保护生物多样性、维护生态安全及促进经济健康发展方面的重要性。进一步地，深入分析了外来物种入侵对林业生态造成的具体影响，包括本地物种受到排挤、生态平衡被打破、病虫害加剧以及林业经济损失等。在此基础上，提出了针对性的防控策略，包括逐步恢复生物多样性、进行生态调控、加强病虫害防控以及发展替代产业等措施。本研究通过综合运用生态学、植物学等理论与方法，旨在为林业生态系统的保护与管理提供科学依据和实践指导，促进生物多样性的保护与林业经济的可持续发展，为应对外来物种入侵挑战提供有效策略。

Abstract
This paper aims to comprehensively explore the impact of alien species invasion on forestry ecology and its prevention and control strategies. Firstly, the definition, classification criteria and invasion route of alien species are summarized, and the research background is clarified. Then, the importance of preventing alien invasion in protecting biodiversity, maintaining ecological security and promoting healthy economic development. Further, the specific impact of alien species invasion on forestry ecology was analyzed, including the exclusion of local species, broken ecological balance, increasing diseases and pests, and economic loss of forestry. On this basis, targeted prevention and control strategies are put forward, including the gradual restoration of biodiversity, ecological regulation, the strengthening of disease and pest control, and the development of alternative industries. By making comprehensive use of ecology and flora, this study aims to provide scientific basis and practical guidance for the protection and management of forestry ecosystem, promote the protection of biodiversity and the sustainable development of forestry economy, and provide effective strategies for the challenge of foreign species invasion.
Key words: Exotic species; forestry ecology; prevention and control countermeasures
