摘要
外来海洋生物是基于某一物种所具有的经济或社会意义而从外地有目的地引进，或者由于无意识的活动如航运业中的船体附着以及压舱水的排放等而带入的。外来海洋生物可能会对当地的生态系统直接或间接地造成影响，如与土著生物争夺生活空间，破坏生态环境；与土著生物杂交，造成遗传污染；带入病原生物；导致海域生态灾害加剧等。综述了我国外来海洋生物的种类以及可能存在的生态影响，以期初步了解我国外来海洋生物的现状，为我国有关外来海洋生物的管理以及相关法律法规的制定提供参考。
Many species of alien marine organism were introduced to China by intentional introduction for their economic or social significances or by unconscious activities such as ballast water discharge. The alien marine species may cause direct or indirect impacts on the local ecosystem. For example, the alien species compete with endemic species for ecological niche to destruct the ecological environment; the alien species may bring about genetic pollution due to their hybridization with aboriginal species, the pathogenic organisms may be introduced in company with alien species; many red tide organisms were introduced to China Seas to result in the ecological disasters in China Seas. In this paper, the alien marine species and their ecological impacts in China are reviewed in order to acquire a preliminary understanding of the present status of alien marine species in China, which provides basis for formulating laws and regulations concerning the management of alien marine organisms in China.
