摘要:

旱雀麦(Bromus tectorum)在世界上广泛分布,但在北美却是一种入侵能力较强的物种,对当地的植物群落结构组成和生态系统功能产生重要影响。本文从旱雀麦的生境和扩散路径、本身的生物学特性、其与新栖息地土著物种之间的相互作用、新栖息地的环境变化对旱雀麦的影响等方面综述了近年来关于旱雀麦入侵机制的研究进展。研究表明,影响旱雀麦入侵的因素是多样的,阐明旱雀麦的入侵机制对于推动生态学的理论发展和控制旱雀麦的大规模入侵具有重要意义。

Abstract: Bromus tectorum L. distributes widely around the world, and is a severely invasive species in North America, giving great influence on the local plant community structure and ecosystem function. This paper reviewed the research progress in the invasion mechanisms of B. tectorum from the aspects of habitat, spreading route, biological characteristics of B. tectorum, interactions among B. tectorum and its new neighbors, and effects of changing ecological factors in new habitats on B. tectorum. According to the recent studies, there are multiple factors affecting the invasion of B. tectorum. To clarify the invasion mechanisms would be essential in developing ecological theories and in controlling the massive invasion of B. tectorum.
