摘要：测定了海南岛霸王岭热带山地雨林不同择伐强度经营试验初期土壤 C、N含量及其储量 ,结果表明 :原始热带山地雨林土壤 C、N背景值分别为 10 8.91t· hm-2 、9.58t· hm-2 ,表层 50 cm土壤 C储量占深 10 0 cm土层 C储量的 77.6 % ,相应的 N储量占 73.8% ;30 %、50 %择伐强度经营 5个月后林地土壤 C储量分别比原始林降低 4 .5%和 5.3% ,但 30 %强度经营林地土壤 C/N接近未采伐的原始林。
Based on the contrast experiment of the felling management,the content of nitrogen and organic carbon in soil were measured in a tropical montane rainforest of Bawangling,Hainan Island.The results showed that the organic carbon and nitrogen were 108.91 t·hm -2 and 9.58 t·hm -2 respectively in the soil layer of 100 cm of the virgin forest,and 77.6 % of organic carbon and 73.8% of nitrogen were stored in surface soil of 50 cm.Five months later after felling tropical montane rainforest by the intensity of 30% and 50%,the soil carbon storage declined by 4.5% and 5.3% respectively compared with the previous virgin tropical forest.C/N ratio of the soil on the 30% harvest plot was close to that in the virgin forest.
