摘　　要：对克隆植物在林下、草原、荒漠、冻原、农田和水域等6种不同类型生境中的繁殖对策及其生态适应意义进行了归纳和总结,对克隆植物有性繁殖与无性繁殖之间的权衡关系及相对重要性随水分、光照和温度的变化规律进行了阐述。分析表明,在环境条件严酷地区,克隆植物的无性繁殖在种群更新中的相对重要性有所增加。对两种繁殖方式的生态功能特性进行比较,综述了有关二者权衡关系的研究成果及影响二者权衡关系的部分因素。从研究手段上对克隆植物繁殖对策的研究进行了思考与展望。This paper summed up the reproductive strategies and the ecological adaptability of clonal plants in six different habitats such as forest understory,steppe,desert,farmlands and water area,and discussed the trade-off relations or relative importance of sexual vs.asexual reproduction which regularly change with water status,light and temperature.Such regularity was clarified as:the harsher the environment is,the more asexual reproduction would contribute to the regeneration and survival of the populations.In addition,we compared the ecological and functional properties of sexual vs.asexual reproduction modes,reviewed recent researches on the trade-off relations between the two reproductive modes,and mentioned some factors influencing such tradeoff relations.Finally,we made a prospect about future research of reproductive strategy of clonal plants especially in terms of approaches.
