摘　　要：根茎在植物的无性繁殖、克隆分株间信息交流和物质交换、预测资源斑块的质量等方面具有重要意义,并且根茎克隆植物的研究涉及生物入侵、全球变化等诸多生态学前沿领域。作为一种重要的克隆植物类型,根茎克隆植物在资源异质性生境中表现出特有的适应方式,这种方式可以通过形态可塑性、觅食行为、生理整合以及适合度来具体表征。着眼于根茎克隆植物,总结和分析了国内外近年来的研究案例,并对形态可塑性起源与多样性的限制假说和适应假说、觅食行为中的强度觅食和广度觅食策略、克隆分株间间隔子保持和断裂的利益权衡等热点内容进行了讨论。最后联系生态学学科前沿,提出了本领域在未来需要重视的研究方向。The rhizomes of plants play an important role in many aspects,including asexual reproduction,communication and resource sharing between ramets,and foraging in heterogeneous environments.Rhizomatous clonal plants are popular research subjects in fields such as invasion ecology and global change biology.Rhizomatous clonal plants show a special adaptation to heterogeneous habitats through morphological plasticity,foraging behavior,physiological integration,as well as fitness.This paper summarizes and analyzes domestic and international case studies of rhizomatous clonal plants from recent years.Some current issues are discussed,such as the limit hypothesis and the adaptation hypothesis on the origin of morphological plasticity and diversity,intensive foraging and extensive foraging in foraging behavior,and the benefit of ramet spacer＇s maintain or break.Finally,research priorities for this domain are presented.
