摘　　要：应用时空替代方法,于中国福建省长汀县水土流失区开展研究,探讨了不同恢复梯度和生活史阶段下马尾松功能性状与生长率的关系。结果显示,在中低恢复梯度下,叶干物质含量与生长率的关系显著,而比叶面积、叶片氮含量和叶片磷含量在不同恢复梯度下对生长率的影响均不显著,表明叶干物质含量在生态恢复早期对生长起着关键作用。在不同生活史阶段中,性状-生长率关系存在差异,幼苗阶段个体的生长受到功能性状的影响较其他阶段更加显著,表明功能性状对处于早期生活史阶段个体的生长具有更强烈的影响。本研究解析了生态恢复过程中马尾松的功能性状变化对生长的影响,为生态恢复区的植物管理与科学研究提供了数据支持与理论参考。Using a space-for-time substitution approach,this study explores the relationship between functional traits and growth rate of Pinus massoniana across different restoration gradients and life history stages in the soil erosion-prone areas of Changting County,Fujian Province,China.The results show that leaf dry matter content is significantly correlated with growth rate in low and medium restoration gradients,whereas specific leaf area,leaf nitrogen content,and leaf phosphorus content show no significant effects on growth rate across these gradients,indicating that leaf dry matter content plays a crucial role in early stages of ecological restoration.The trait-growth relationships vary among life history stages,with growth in juveniles being more strongly influenced by functional traits than in other stages,suggesting that functional traits have a more pronounced effect on growth in early life history stages.This study provides insights into the impact of functional trait changes on the growth of P.massoniana during ecological restoration,offering valuable data and theoretical insights for plant management and scientific research in restoration areas.
