摘　　要：克隆植物因特殊的克隆整合和空间拓展特性,在异质生境下展示出较高的生态适应性及适合度,这是其广泛存在于各类生态系统的一个重要原因。目前对克隆整合在个体或种群水平的生态学效应已有较深认识,而对群落及生态系统的影响及作用机制则明显关注不足。前期研究表明,克隆整合对土壤理化性质、根际微生物及个体竞争力均有显著影响,从而有利于克隆植物的成功入侵、生境修复及植被重建等。对群落及生态系统水平的克隆整合生态学效应的研究进行归纳和总结,分析了克隆整合对植物群落结构和生产力、根际微生物和土壤动物、生态系统碳固持、养分循环等的影响;阐释了克隆整合及空间拓展特性对退化生态系统的修复及作用机制,并指出今后克隆整合的研究应同时考虑微观(根际过程)和宏观(群落及生态系统)层次的效应以及短期与长期的效应。可将克隆整合与植物-土壤反馈等其他生态过程相联系,综合探究克隆整合的生态学意义。Due to the special attributes of clonal integration and spatial expansion,clonal plant species show high ecological adaptation and fitness in heterogeneous environments.It may be one of the important reasons for their widespread distribution in ecosystems.Currently,the effects of clonal integration have been well studied at individual and population levels,but have received much less attention at community and ecosystem levels.Previous studies have shown that clonal integration could influence individual competitiveness,soil physical and chemical properties,and rhizosphere microorganisms.These effects of clonal integration are conducive to the successful invasion of alien clonal plants and are also potentially useful for habitat restoration and vegetation reconstruction.In this review,we summarized the impacts of clonal integration on communities and ecosystems where clonal plant species played dominant roles.Firstly,we reviewed the effect of clonal integration on community structure and productivity,rhizosphere microorganisms,soil fauna,carbon sequestration and nutrient cycling.Secondly,we elucidated the potential mechanisms underlying the roles of clonal integration and spatial expansion in restoring degraded ecosystems.We proposed that future studies of clonal integration should consider both micro(e.g.,rhizosphere process)and macro(e.g.,community and ecosystem)levels and both short⁃and long⁃term impacts.Additionally,to synthetically understand the ecological significance of clonal integration,future studies should link it with other ecological processes such as plant⁃soil feedback.
