摘　　要：This research estimates carbon sink and allocation in above-and below-ground biomass of a 12-year-old willow coppice plantation on fl uvisol soil near the Vistula River(southern Poland).The plantation showed high C sink potential and sequestration rates.C sequestration by aboveground biomass was estimated at 10.8 Mg C ha^−1 a^−1.Accumulation in coarse roots was estimated at 1.5 Mg C ha^−1 a^−1 and in fi ne roots at 1.2 Mg C ha^−1 a^−1.Total C sequestered(above-ground biomass,coarse roots and fi ne roots)was estimated at 13.5 Mg C ha^−1 a^−1.These results confi rm the potential of fast-growing plantations of willow to mitigate,over a short time span,the eff ects of high CO 2 concentrations.
