摘要:暖温带落叶阔叶林是暖温带地区最典型的植被类型之一,东灵山地区该类型天然次生林恢复演替良好。凋落物作为土壤有机质的主要来源以及影响地表环境的重要因子,在森林生态系统物质循环和稳定性维持中起着重要作用。按照中国生态系统研究网络(Chinese Ecosystem Research Network,CERN)的统一规范,在野外固定样地安装27个凋落物框,收集了2005-2015年东灵山暖温带落叶阔叶林凋落物各组分(枯枝、枯叶、落花或果、树皮)回收量的季节动态数据回收量季节动态。本数据集的建立与共享,为理解全球变化条件下暖温带落叶阔叶林的生态系统养分循环过程和碳循环机理提供了数据支撑,对推动我国植被生态学和长期生态学研究具有重要意义。

Abstract & Keywords
Abstract: Warm temperate deciduous broad-leaf forest is one of the most typical community types in warm temperate zone. Dongling mountain forest is one of the well-preserved natural secondary forests belonging to this forest type. As the main source of soil organic matter and an important factor affecting the soil surface environmental, litters play an important role in the matter circulation and stability maintenance of forest ecosystem. According to the unified specification of Chinese Ecosystem Research Network (CERN), 27 litter traps were installed in the permanent plot to collect the seasonal dynamics of litter recovery in the warm temperate deciduous broad-leaved forest in Dongling mountain from 2005 to 2015. The monthly litter dry weight was divided into dead branches, dead leaves, flowers or fruits and also tree bark. The establishment and sharing of the dataset of seasonal dynamics of the littler fall production of deciduous broad-leaf forest in the warm temperate will provide important data support for understanding the nutrient cycling process and carbon cycling mechanism in the ecosystem of warm temperate deciduous and also significance promote the study of vegetation ecology and long-term ecology in China.
Keywords: secondary forest; litter yield; nutrient cycling; carbon cycling
