Temporal stability of aboveground biomass and productivity in temperate forest in northeast China
Listed in ScienceDB
These data were collected from two permanent temperate forest plots in northeastern China.
Description
The dataset includes the temporal stability of aboveground biomass and productivity, as well as aboveground structural diversity, leaf trait diversity, root trait diversity, soil fertility, among-species asynchrony, and within-species stability in a 5-ha young-growth forest plot and a 25-ha old-growth forest plot.Censuses of the 5-ha young-growth forest plot were conducted in 2005, 2010, 2015, and 2021, while the 25-ha old-growth forest plot was censused in 2004, 2009, 2014, and 2019.
In each census, all woody individuals with a diameter at breast height (DBH) ≥ 1 cm were identified to species, tagged, measured, and mapped. Species-specific allometric equations were used to estimate aboveground biomass for each living individual across census periods.Each forest plot was subdivided into 20 m × 20 m quadrats. For each quadrat, standing aboveground biomass was calculated in Mg ha⁻¹, and aboveground productivity was calculated in Mg ha⁻¹ yr⁻¹.

The temporal stability of aboveground biomass and productivity was calculated across census years as the inverse of the temporal coefficient of variation.The variables are defined as follows:Code: quadrat numberbio.mean: mean aboveground biomassbio.sd: standard deviation of aboveground biomassbio.stability: temporal stability of aboveground biomassnet.mean: mean aboveground productivitynet.sd: standard deviation of aboveground productivitynet.stability: temporal stability of aboveground productivitybio.asynchrony: among-species asynchrony of aboveground biomassnet.asynchrony: among-species asynchrony of aboveground productivitybio.sp.stability: within-species stability of aboveground biomassnet.sp.stability: within-species stability of aboveground productivityRoot.FDis: root trait diversity, calculated using the functional dispersion indexLeaf.FDis: leaf trait diversity, calculated using the functional dispersion indexSoil.pc1: the first principal component axis of soil variables, representing the main soil fertility gradientFHD.M2.NPC.2021: aboveground structural diversity derived from UAV-LiDAR data, represented by foliage height diversity in 2021
