摘　　要：天然更新是森林生态系统中重要的生态学过程,是森林恢复的根本途径。种子更新和萌蘖更新是森林天然更新的两种方式,各有优劣、相互补充。森林天然更新的早期过程被视为树木建植的瓶颈期,因此,研究木本植物种子和萌蘖更新的早期过程对于理解森林天然更新机制、预测种群/群落发展方向和明确森林恢复途径具有重要意义。本文总结了木本植物两种天然更新方式权衡的生态学意义及影响因素,对比了两种天然更新起源幼苗特性的差异,总结了生物因子、非生物因子、干扰等对种子更新和萌蘖更新早期过程的影响。在此基础上提出了现有研究中存在的主要问题,并指出今后应加强对森林萌蘖更新早期过程的研究,开展森林天然更新影响因子及干扰机制的综合研究,重视森林天然更新理论对森林管理实践的指导作用,为促进森林天然更新、实现森林可持续发展提供科学支持。Natural regeneration is a significant ecological process in forest ecosystems and the foundational approach of forest restoration. As two basic modes of natural recruitment of woody species,seed regeneration and sprout regeneration have advantages and disadvantages and complement each other. The early process of forest natural regeneration is the bottleneck of sapling establishment. Thus,it is necessary to compare the early processes of seed and sprout renewal for understanding forest natural regeneration,predicting population/community development,and identifying pathways for forest restoration. Here,we reviewed the ecological significance and influencing factors of tradeoff between two natural regeneration modes of woody species,compared the differences in the characteristics of seed-and sprout-origin seedlings,and summarized the effects of biological factors,abiotic factors and interference on the early process of these two regeneration pathways. The main problems in the current research are proposed. In the future,more attention should be paid to the study of early sprout regeneration process,comprehensive research of forest regeneration impact factors and the interference mechanism should be carried out,and the guiding role of forest natural regeneration theory in forest management practice should be highly appreciated,aiming to provide scientific support for promoting natural regeneration and sustainable development of forests.
