摘要
滨海湿地是海陆相互作用下形成的特殊生态系统,对其群落更新机制的理解,有助于维护湿地生态系统的稳定和持续发展。土壤种子库是群落潜在更新能力的重要组成部分,可以通过“储藏效应”缓冲外界对生态系统的干扰,对保护物种多样性和维持群落稳定性具有重要价值。本文在阐明土壤种子库形成机制和功能特征的基础上,从土壤种子库的分布格局、与地上植被以及与环境条件之间的关系等方面,阐述了湿地土壤种子库的研究现状,以及土壤种子库在滨海湿地生态系统中的重要地位和存在意义;提出将入侵种影响下的野外自然群落研究和土壤种子库结构研究相结合,深入了解群落更新能力、预测群落未来可能的发展趋势,为全球变化背景下开展被入侵湿地生态系统恢复的教学及探究活动提供科学依据。
Coastal wetlands are special ecosystems formed by the interaction between land and sea.Understanding the community regeneration mechanisms within these habitats is instrumental in maintaining the stability and ensuring sustainable development of wetland ecosystems.The soil seed bank serves as an important part of the community s potential regeneration capacity.It can buffer external disturbances to the ecosystem through the“storage effect”,thereby playing a pivotal role in preserving biodiversity and maintaining the stability of community.Based on an understanding of the formation mechanisms and functional features of soil seed banks,this paper probes into the research status of wetland soil seed banks,including their spatial distribution,correlations with aboveground vegetation,and environmental conditions.It also highlights the important role and significance of soil seed banks within coastal wetland ecosystems.The study proposes an integrated approach,combining research on natural communities impacted by invasive species with analyses of soil seed bank structures.This method aims to gain a deep understanding of community regeneration capacities and predict possible future development of communities,providing scientific basis for educational strategies and investigative activities tailored to the restoration of invaded wetland ecosystems in the context of global change.
