以海南岛尖峰岭热带林生态系统定位研究站多年来的研究作为基本数据，用两种方法（生物量法和蓄积量法）计算了海南岛和用一种方法（蓄积量法）计算了云南南部热带森林的Ｃ素库总量。结果表明，海南热带天然林（含原始林和天然更新林）的Ｃ素库总量为０．７１９～０．７３４亿ｔ，云南南部的热带天然林的Ｃ素库总量在０．６５３亿ｔ以上。因此我国热带林目前的Ｃ总量在１．３７２～１．３８７亿ｔ以上。
Taking the study of the Hainan Peninsula Jianfengling Tropical Forest Ecosystem Research Station for many years as the basic data, Hainan Island was calculated by two methods (biomass method and stock volume method) and Yunnan Province was calculated by a method (stock volume method) The total amount of C primes in the southern tropical forests. The results showed that the total amount of C primes in Hainan’s tropical natural forests (including virgin forests and natural regeneration forests) was 0.719-0.734 billion tons, while that of tropical natural forests in southern Yunnan was 65.53 million t above. Therefore, the current total amount of tropical forest in China is 1.372 ~ 1.387 billion t.
