厦门海洋生物外来物种和生物入侵

生物入侵是指外来种在某地区定居、繁衍、扩散,并造成危害的过程.生物入侵已成为全球性的环境问题,它对生态系统、环境和社会经济的影响日益明显.本文讨论互花米草（Spartina alterniflora Loisel）和沙饰贝（Mytilopsis salleReeluz）的分类学、生物学及其在厦门的引入、扩散过程,简要分析厦门海洋生物入侵的现状、危害及治理方法,指出对外来海洋生物入侵开展全面深入的研究和治理势在必行.

Present Status of Marine Biological Invasions in Xiamen

Biological invasion is the transitions of exotic species,colonization,multiplication,diffusion and its damages at a certain area. It has become a global environmental issue,and has an increasingly remarkable impact on ecosystem,environment and social economy. The taxonomy,biology and the import and diffusion process of Spartina alterniflora and Mytilopsis sallei were discussed in this paper. The status,impacts and cure strategies of the marine biological invasions in Xiamen were briefly studied. Studying marine biological invasion thoroughly and comprehensively is imperative under the situation.
