鱼类入侵的过程、机制及研究方法

当前生物入侵问题已成为一个危害自然生态环境、生物多样性及人类社会可持续发展的国际问题，其中鱼类入侵的影响不容忽视.本文在国内外已有研究基础上，从入侵鱼类的自身特性、入侵地的特征、外来种与土著种之间的相互关系、外来种的适应性进化几个角度综合分析了鱼类入侵的机制，并概括了国内外鱼类入侵过程和研究方法的进展.

Process, mechanism, and research method of fish invasion

Fish invasion has become a serious environmental and economic damage,and obtained a priority concern by the conservation ichthyologists and land managers.A better understanding of the invasive mechanisms is of significance in developing ecological theories and in controlling exotic pests.In this paper,the progress in studying the mechanisms of fish invasion was reviewed,involving the biological characteristics of exotic fish,their adaptive evolution,interactions among exotic and indigenous fish,and relationships between species diversity and community resistance to invasion,etc.The study of invasive process and the progress of research methods were discussed.
