2005–2015年北京东灵山暖温带落叶阔叶林凋落物回收量季节动态数据集

A dataset of seasonal dynamics of the litter fall production of deciduous broad-leaf forest in the warm temperate zone of Beijing Dongling Mountain(2005–2015)

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,在维持森林生态系统物质循环及其稳定性中起着重要作用。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一定意义。

Warm temperate deciduous broad-leaf forest is one of the most typical vegetation types in a warm temperate zone.The natural secondary forests of this type in Dongling Mountain area have experienced satisfactory restoration and succession.As a major source of soil organic matter and an important factor affecting the soil surface environment,litters play an important role in the matter circulation and stability maintenance of forest ecosystem.According to the unified specifications of Chinese Ecosystem Research Network(CERN),27 litter traps have been 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 is distributed on dead branches,dead leaves,flowers or fruits,and tree bark.Setting up and sharing this dataset will provide important data support for understanding the nutrient cycling process and carbon cycling mechanism in the ecosystem of warm temperate deciduous broad-leaf forest,and will also have great significance to promote the study of vegetation ecology and long-term ecology in China.
