摘要
水深和氮营养是影响湿地植物生长的关键因素,植物功能性状反映植物对环境变化的适应策略,研究水深和氮营养添加对湿地植物功能性状的影响有助于预测未来环境变化下其生长与分布趋势的变化。特别是在全球变化和人类活动的影响下,水深和氮营养变化对湿地植物功能性状的影响会更加深刻而复杂。本文分别从水深、氮添加及两者交互对湿地植物的生长性状、克隆繁殖性状和生物量积累等方面的影响,总结了国内外的相关研究工作。提出未来应该加强对湿地植物地下及克隆繁殖性状的研究,重点关注多尺度长时间序列的系统性研究,深入探究水深和氮添加交互对湿地植物功能性状的影响。
Water depth and nitrogen nutrition are the key factors affecting the growth of wetland plants.Plant functional traits reflect plant adaptation strategies to environmental changes.Studies on the effects of water depth and nitrogen addition on the functional traits of wetland plants can help predict the growth and distribution of wetland plants under future environmental changes.Under the scenario with the impacts of global changes and human activities,the effects of changes in water depth and nitrogen enrichment on the functional traits of wetland plants can be more profound and complex.Here,we summarized the effects of water depth,nitrogen addition,and their interactions on growth-related traits,clonal reproductive traits,and biomass accumulation of wetland plants.In the future,we should pay more attention to strengthen the research in belowground and clonal reproductive traits of wetland plants,emphasize multi-scale and long-term series research,and further explore the interactive effects of water depth and nitrogen addition on the functional traits of wetland plants.
