摘 要
在全球化的背景下，人类活动频繁，加速了物种的跨地域传播，导致外来物种入侵成为全球面临的重大生态问题之一。林业生态系统作为自然环境中的重要组成部分，其健康与稳定直接关系到生物多样性的维持、生态平衡的建立以及人类社会的可持续发展。外来物种一旦成功入侵林业生态系统，往往能够迅速繁殖并占据优势地位，对原生物种构成严重威胁，导致生物多样性急剧下降，土壤和水文条件发生改变，进而影响林业生产与管理，加剧社会经济负面影响。因此，深入研究外来物种入侵对林业生态的影响及其防控对策，对于保护生态环境、促进林业可持续发展具有极其重要的意义。本文旨在探讨外来物种入侵对林业生态的影响及有效的防控对策。通过综述国内外研究现状，分析外来物种入侵的定义、特征及其传播途径，系统阐述了外来物种入侵对生物多样性、土壤与水文条件、林业生产与管理以及社会经济等方面的影响。在此基础上，本文提出了增强生物多样性保护措施、改善土壤与水文条件管理、优化林业生产与管理模式以及缓解社会经济负面影响等防控对策。通过实施这些综合防控策略，旨在有效遏制外来物种入侵的蔓延趋势，保护林业生态系统的健康与稳定，促进生物多样性的恢复与提升，为林业可持续发展提供有力保障。

Abstract
In the context of globalization, frequent human activities accelerate the cross-regional transmission of species, leading to the invasion of alien species as one of the major ecological problems facing the world. As an important part of the natural environment, the health and stability of forestry ecosystem are directly related to the maintenance of biodiversity, the establishment of ecological balance and the sustainable development of human society. Once the alien species successfully invade the forestry ecosystem, they can often reproduce quickly and occupy a dominant position, posing a serious threat to the native species, leading to a sharp decline in biodiversity, changes in soil and hydrological conditions, thus affecting forestry production and management, and aggravating the negative social and economic impact. Therefore, it is of great significance to deeply study the influence of alien species invasion on the forestry ecology and its prevention and control countermeasures to protect the ecological environment and promote the sustainable development of forestry. This paper aims to explore the impact of alien species invasion on forestry ecology and the effective prevention and control countermeasures. By summarizing the current research situation at home and abroad, analyzing the definition, characteristics and transmission routes of alien species invasion, we systematically expounded the influence of alien species invasion on biodiversity, soil and hydrological conditions, forestry production and management, and social economy. On this basis, this paper puts forward the prevention and control measures such as enhancing biodiversity protection measures, improving soil and hydrological conditions management, optimizing forestry production and management mode, and alleviating the negative social and economic impact. Through the implementation of these comprehensive prevention and control strategies, it aims to effectively curb the spread trend of alien species invasion, protect the health and stability of the forestry ecosystem, promote the recovery and promotion of biodiversity, and provide a strong guarantee for the sustainable development of forestry.
