摘　　要：森林病虫灾害是病原物或昆虫、树木、环境、人类活动之间相互影响,导致森林生态系统不稳定性加剧、调节功能失调后的产物。森林生态系统组成多样性和结构复杂性是实现森林生态系统对病虫灾害自我调控功能的基础条件。在林分尺度基础上,总结了森林生态系统组成和结构对病原物和害虫建群和危害的影响机制,提出以生态调控策略为理论基础,以调控林分组成和结构为切入点,揭示森林生态系统对病虫灾害自我调控的自组织机理,为实现我国森林病虫灾害的可持续控制提供理论依据。Forest pest disaster was the outcome of the increase of forest ecosystem instability and the loss of balance function which were affected by multiple effects and interactions of pests,trees,environment and human activities.Composition diversity and structure complexity of forest ecosystem were the fundamental requirements of self-regulation function to forest pest disasters.The review suggested impact mechanism of composition diversity and structure complexity of forest ecosystem on colonization and damage of pests on a stand scale and revealed the self-organizing mechanism of forest ecosystem self-regulation of pests with managing forest composition and structure as a corresponding point based on the theory of ecological management,aiming at providing basic theory for the sustainable control of forest pests in China.
