摘要: 对海南岛尖峰岭热带山地雨林原始林和更新林的C素库以及皆伐对森林C素库影响的研究表明,尖峰岭热带山地雨林原始林的C素库总量为340.467t·hm-2, 其中植物C储量为232.791t·hm-2, 土壤有机碳储量为104.696t·hm-2, 枯枝落叶层C储量为2.98t·hm-2. 更新林的C素库总量为258.996t·hm-2, 其中植物C储量为150.203t·hm-2, 土壤有机C储量为105.803t·hm-2, 枯枝落叶层C储量为299t·hm-2. 皆伐可使森林土壤有机碳储量减少,而天然更新又可使土壤有机碳储量较快地恢复。皆伐后经过26年的天然更新,森林C素库只恢复到原来的76%左右。

Abstract: Studies on the carbon pool of virgin and regenerated tropical mountain rain forests in Jianfengling, Hainan Island, China, and the effect of clear-cutting on it show that the total carbon pool of virgin tropical mountain rain forest was 340.467t·hm-2, of which, the storage of plant carbon, soil organic carbon and litter layer carbon accounted for 232.791, 104.696 and 2.98t·hm-2, respectively.The total carbon pool of regenerated tropical mountain rain forest was 258.996t·hm-2, of which, the storage of plant carbon, soil organic carbon and litter layer carbon accounted for 150.203, 105.803 and 2.99t·hm-2, respectively.Clear-cutting could cause the decrease of carbon storage of forest soil, and natural regeneration could make the carbon storage recover fast.After clear-cutting, the total carbon pool of 26-year-old natural regenerated forest was only 76% of that of the virgin forest.
