摘要
芦苇是世界重要的湿地物种,它是一种对环境干扰表现十分敏感的克隆植物。本文综述了芦苇的起源、扩张与衰退,并进一步探讨了芦苇扩张与衰退的原因可能是由于人为的干扰与更有竞争力的基因型侵入造成的。为了更好的利用芦苇资源,人类应采取的策略是最大限度地减少对芦苇生境的干扰。
The common reed Phragmites australis (Cav.) Trin.ex Steud. is a clonal plant which is sensitive to environmental disturbances. In the paper, origin, expansion and decline of Phragmites australis were summarized, and the reasons for expansion and decline were the disturbance of human activity and genotype invasion. In order to better use reed resource, mankind should try his best to reduce the disturbance to reed habitat.
