生物入侵机制研究进展

本文从外来种本身的生物学特性，外来种与新栖息地土著种之间的相互作用，群落生物多样性对入侵种的抵抗能力，新栖息地生态环境变化对入侵种的影响等方面综述了近年来有关生物入侵机制的研究进展，并探讨了研究方法的发展和亟待解决的问题，大量的研究表明生物入侵机制是极为多样的，可能没有一般的，通用的机制，阐明生物入侵的机制，对推动生态学理论的发展和控制有害外来种有重要意义。

Progress in studies on mechanisms of biological invasion

Recent progress in studying mechanisms of biological invasion is reviewed involving several aspects, such as biological characteristics of exotic species, interaction among exotic species and their new neighbours, the relationships between species diversity and community resistance to invasion, the effects of changing ecological factors in new habitats. We also analyze the progress of research methodologies and some unsolved vague points in this field. According to recent studies, the mechanisms of biological invasion seem so diverse that no common pattern could explain all cases. A better understanding of invasive mechanisms is essential in developing ecological theory and significant in controlling exotic pests.
