火是森林生态系统演替过程中的一种自然干扰因子,在促进森林发育、维持生物多样性特别是景观多样性方面起着积极的作用。森林中的多种干扰间有关联性,火灾、虫害和病原体之间存在着复杂的相互作用。文中综述了火干扰与森林病虫害的相互影响。火灾会引起森林组成和景观的变化,进而影响森林病虫的生存与发生条件。病虫害通过改变可燃物特性及其分布,影响火烧频度和强度。这一研究领域的未来发展趋势是更注重火与病虫害之间的量化关系,研究结果将为开展科学的林火管理提供理论依据,实现森林经营的可持续。
Fire is a natural disturbance factor in forest ecosystem succession and plays a positive role in promoting forest development and maintaining biodiversity, especially landscape diversity. There is a complex interaction between fire, pests and pathogens in the interdependence of multiple disturbances in forests. The paper summarizes the interaction between fire disturbance and forest pests and diseases. Fire can cause changes in forest composition and landscape, which in turn affects the conditions for the survival and development of forest pests and diseases. Pests and diseases affect the frequency and intensity of fire by changing the characteristics and distribution of combustibles. The future trend of this research field is to pay more attention to the quantitative relationship between fire and pests. The results of this study will provide a theoretical basis for carrying out scientific forest fire management and achieve the sustainable forest management.
