  • 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.
