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。
Bromus tectorum is widely distributed in the world, but it is a highly invasive species in North America, which has a significant impact on the composition of the plant community and its ecosystem function. In this paper, we reviewed the habitat and diffusion path of A. capitatum, its biological characteristics, its interaction with indigenous species in new habitats, the impact of environmental changes in new habitats on L. chamaejasme Research Progress on the Mechanism of Invasion of. The research shows that there are many factors that affect the invasion of A. lanceolata. It is of great significance to elucidate the mechanism of A. langeola invasion to promote the theoretical development of ecology and control the large-scale invasion of L. latifolia.
