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.
