摘要/Abstract

摘要： 雌雄异株植物作为陆地生态系统的重要组成部分，在维持生态系统结构和功能稳定性方面发挥着关键作用。但是，由于雌雄异株植物的不同性别植株在形态特征、生理特征和资源分配等方面均存在明显差异，至今对全球气候变化背景下雌雄植物的性别差异响应机制的认识仍十分有限。本文综述了全球变暖、降水变化和大气CO₂浓度升高等主要气候因子变化对雌雄异株植物的影响，探讨了雌雄异株植物对气候变化响应的性别差异，提出了未来雌雄异株植物与气候变化关系研究的重点，以期为揭示陆地生态系统结构和功能稳定性对气候变化的响应机制提供参考依据。

Abstract:

Dioecious plants represent an important part of the terrestrial plants and play a relevant role in regulating the ecosystem structure and function. The female and male plants differ significantly from each other in their morphological and physiological characteristics, as well as in their resource allocation strategies. However, their sex-specific responses to climate changes and the potential mechanisms are still less studied up to date. In this paper, we reviewed the sex-specific responses of dioecious plants to climate changes, including global warming, precipitation change, and elevated atmospheric CO₂ concentration. Based on literature analysis, we also discussed the mechanisms of such sexspecific responses of dioecious plants to climate changes. Finally, the potentially important study fields for dioecious plants in the context of global climate changes were presented. The review is expected to make a scientific contribution to understanding the stability of structure and function of ecosystems, especially for those ecosystems dominated by dioecious plants, under global change.
