【摘要】通过实地调查取样和室内试验测定,对宁夏贺兰山自然保护区青海云杉林碳储量进行了研究。结果表明,青海云杉(Picea crassifolia)林是宁夏贺兰山主要的森林碳库之一,总有机碳储量为24.771 kg·m-2,其中林木碳储量为5.960 kg·m-2,地被层有机碳碳储量为0.491 kg·m-2,土壤层有机碳储量为18.320 kg·m-2。其中土壤层有机碳储量占总有机碳储量的比重达73.96%,是青海云杉林主要的有机碳库。更多还原

【Abstract】 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 of24. 771,5. 96,0. 491 and 18. 32 kg·m- 2for 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.更多还原
