Biophysical drivers of the carbon dioxide, water vapor, and energy exchanges of a short-rotation poplar coppice

Popis výsledku v původním jazyce

We used the eddy-covariance technique to measure the temporal dynamics and the relationships between leaf area index (LAI) and exchanges of carbon dioxide (CO2), latent heat (LE) and sensible heat (H) in a multi-genotype short-rotation poplar coppice (SRC) located in East-Flanders (Belgium). The study was carried out over four years (2010?2013) corresponding to the first two rotations of the plantation. The net carbon (C) balance during the first two-year rotation was 75.2 (4.4) g C m2 in the establishment year 2010 and 95.6 (5.9) g C m2 in 2011. After the harvest (second two-year rotation) the coppice was a net source of carbon, 151.0 (10.5) g C m2 in 2012, but a sink of 274.6 (18.8) g C m2 in 2013. Overall, at the end of the second rotation this SRC,was a net CO2 sink with a cumulative uptake of 144.0 (22.8) g C m2. The temporal dynamics and the magnitude of the ratio between gross primary production (GPP) and ecosystem respiration (Reco) were similar to a deciduous forest. The evol
