摘要
鞭生竹(散生竹和混生竹)作为典型的克隆植物,具有发达的鞭根系统和快速生长的特性。在异质性环境中,鞭生竹通过调节分株位置实现觅养行为,产生2种克隆生长格局,生物量分配格局发生改变;生理整合作用的存在可为克隆分株提供生长所需要的各种养分,增强分株的竞争能力。鞭生竹克隆生长使其能够入侵相邻林分,并逐渐发展为新的"优势种",成为一种"局部入侵"物种,影响周围森林群落结构、土壤质量、幼苗更新及幼树生长,从而影响整个森林生态系统。在综合相关研究的基础上,文中对鞭生竹克隆生长特性及其对相邻系统的影响进行归纳总结,提出了今后研究需要重点关注的问题。
As a group of typical clonal plants, whip bamboo （ monopodial bamboo and amphipodial bamboo） has developed rhizome system and fast-growing characteristics. In heterogeneous environment, whip bamboo could realize the foraging behavior through regulating ramet position, produce two kinds of clonal growth pattern and change the biomass allocation patterns. Existence of physiological integration provides various nutrients for clonal ramets, and then enhances the competition ability of clonal ramets. With the characteristics of clonal growth, whip bamboo could invade adjacent forests, and gradually develop into a new ＂dominant＂ species and become a kind of ＂local invasion＂ species, which will affect the forest community structure, soil quality, regeneration of seeding and sapling growth and even the entire forest ecosystem. In this paper, we reviewed current research advances on clonal growth characteristics of whip bamboo and its influence on adjacent system and provided the key issues that need to be concerned in the future.
