Abstract:

Biomass Production and Carbon Sequestration in Poplar-Crop Agroforestry Ecosystems in Eastern Henan Plain Abstract：Agroforestry systems have a great potential for storing and sequestering carbon because of the close interaction between crops, trees and soil. It has been suggested that agroforestry system is one of efficient manners to use land in reducing CO₂ concentration and alleviating CO₂-induced global warming. It will have a great impact on flux and long-term storage of C in the terrestrial biosphere. The present experiment investigated the biomass productivity and carbon sequestration in poplar-crop agroforestry ecosystems at different forest ages of 5, 9, 11 and 13 years old in the eastern Henan plain. The results showed that: the biomass of poplar-crop intercrop agroforestry ecosystems at different ages of 5, 9, 11 and 13 years old was 33.03, 103.06, 124.30 and 154.60 t·hm^-2, respectively; the average net-production was 19.95, 29.30, 33.2 and 56.94 t·hm^-2a^-1, respectively. The total carbon sequestration was 19.86, 52.42, 62.45 and 76.44 t·hm^-2.

Key words: agroforestry ecosystems, poplar-crop intercrop, material production, biomass, carbon sequestration`
