摘要: Data of classification, origin, pathway and environmental impacts of invasive alien micro-organisms, invertebrates, amphibians and reptiles, fish, birds, mammals, weeds trees and marine organisms in terrestrial, aquatic and marine ecosystems of China,were analyzed based on hterature retrieval, field survey and consultation. Some 283 invasive alien species were recorded in China, including 19 invasive alien micro-organisms, 18 aquatic plants, 170 terrestrial plants 25 aquatic invertebrates, 33 terrestrial invertebrates, 3 amphibians and reptiles, 10 fish, and 5 mammals, Of the invasive alien species, 5.5.1% originated from North and South America, 21 7% from Europe, 9,9% from Asia, 8.1% from Africa and 0.6% from Oceania, Many institutions and individuals m China lack adequate knowledge of ecological and environmental consequences caused by invasive alien species, with some ignorance of the dangerous invasion in the introduction of alien species. For instance, 50.0% of invasive alien plants were intentionally introduced as pasture, feedmgstuff, ornamental plants, textile plants, medicinal plants, vegetables, or lawn plants 2.5% of alien invasive animals were intentionally introduced for cultivation, ornament, or biological control, In addition, more efforts are being made in the introduction of alien species and little attention ,s paid on the management of introduced alien species, which may cause their escape into natural environment and potential threats to the environment There were'also gapsin quarantine system in China. All microorganisms were unintentionally introduced, through timber, seedling flowerpot, or soil; 76 3% of alien invasive animals invaded through commodity or transportation tacihty because of the failure of quarantine. Therefore, quarantine measures should be strictly implemented; and meanwhile the intentional introduction of alien species should be strictly managed and a system of risk assessment should be implemented.
