| 摘 要： | 在南北样带温带区选择11个栎属(Quercus)树种的核心分布区, 对各分布区内栎属建群树种的功能性状进行了测定, 并对功能性状间的关系及其对气象因子的响应进行了分析, 以期为气候变化背景下植物-环境关系的深入研究奠定基础。结果表明: 虽然比叶重(LMA)和叶片干物质含量(LDMC)在反映栎属树种生活策略上有着异曲同工的作用, 但是相比之下, LMA的作用略胜一筹; 基于面积的叶片养分含量间的关系较基于质量的更为显著; 除叶片单位面积磷含量(Parea)和单位面积钾含量(Karea)间关系外, 无论是基于面积还是质量的叶片氮(N)、磷(P)含量间的正相关, 均较两者与钾(K)含量间的正相关显著, 这可能与K元素并不直接参与任何稳定结构物质的合成有关。温度和日照时数是影响功能性状间关系的主要气象因子, 与基于质量的养分含量相比, 基于面积的养分含量更易于受温度和日照时数的影响; 降水仅仅影响叶片Parea与其他性状间的关系。 |

| Abstract: | Aims We studied the relationships between functional traits of Quercus species and their responses to meteoro-logical factors in the temperate zone of the North-South Transect of Eastern China (NSTEC),with the objective of finding the dynamics of the relationship between plants and environment. Methods We measured functional traits of Quercus dominant trees in their eleven core habitats in the temperate zone of NSTEC and analyzed relationships among the traits and their responses to meteorological factors. ... |
