摘　　要：常绿落叶阔叶混交林是我国北亚热带地区最具代表性的植被类型。通过野外固定样地凋落物长期观测,本数据集整理了2009–2016年神农架典型常绿落叶阔叶混交林凋落物的月回收量及年现存量,具体包括枯枝、枯叶、落果(花)、树皮、苔藓地衣及杂物的干重。用户可以按照凋落物类型、时间、凋落物器官进行数据检索。典型常绿落叶阔叶混交林凋落物动态数据集的建立与共享,可为全球气候变化背景下该森林类型凋落物的动态研究及不同森林类型凋落物的比较研究提供数据支持,推动关于凋落物研究及常绿落叶阔叶混交林研究的发展。Mixed evergreen and deciduous broadleaved forests are the most representative vegetation type in the subtropical region of China.Based on a long-time litter observation of field sampling plots,the dataset integrated monthly litter recovery amount and annual litter standing crop of the typical mixed evergreen and deciduous broadleaved forests in Shennongjia during the period from 2009 to 2016.It comprised dry weights of branch,leaf,flower and fruit,bark,moss and lichen and other debris.Users can retrieve the data based on litter type,time or organs.Creating and sharing the dataset can help provide data for litter dynamic study of this forest type as well as for litter comparative study among various forest types under the background of global climate change.Additionally,it can also promote the research development on litter and mixed evergreen and deciduous broadleaved forests.

关 键 词：凋落物回收量 凋落物现存量 季节动态 年际动态 植物器官 长期观测
