Carbon storage of Qinghai spruce forest in Ningxia Helan Nature Reserve

Through the field investigation and laboratory analysis, the carbon storage of Qinghai spruce(Picea crassifolia)in Ningxia Helan Nature Reserve were studied. The results showed that Qinghai spruce(Picea crassifolia)forest was the important forest carbon pool in Ningxia Helan mountain where there were organic carbon storage of 24.771, 5.96, 0.491 and 18.32 kg·m-2 for total, the wood, the ground layer and the soil layer, respectively. These results showed that the soil organic carbon storage was the main organic carbon pool in Helan Qinghai spruce forest which accounted for 73.96% of the total organic carbon reserves.
