摘　　要：外来入侵种问题越来越受到关注 ,其对经济、人类生活、环境和生物多样性的危害也被广泛认识。结合介绍外来入侵种的定义、危害性和入侵过程 ,对入侵种的生物学特征、易受入侵种危害的生态系统的特征和控制措施进行了归纳 ;结合国内外研究和管理现状 。One of the unintended consequences of trade globalization is an increase in invasions by exotic pest,which is especially true with the cases in China after 1978 when the country opened its door to the world.With recent outbreaks of a few exotic forest pests such as pine wood nematode,red turpentine beetle,etc.which threat forest ecosystems in large part of China,forest exotics cause quite public concern and awareness.By defining the concept of biological invasion,we illustrated in the paper the process of forest exotic pest invasions from arrival,establishment,spread to persistence phases,impact of forest pest invasions and management strategies and options corresponding to those stages combined with cases.We also proposed measures and options to tackle the invasions in China both in management and research.The increasing threat and impact magnitude of biological invasion on forest ecosystems and economy necessitate increased efforts to reduce the incidence and impact of pest invasions from both relevant government agencies and scientific community with consideration to China‘s accession to the WTO and consequently the perceived trading volume increases.
