摘　　要：分别采用固定深度法、等效质量法和纵向拟合法对海南植胶区土壤有机碳储量进行了估算。结果表明,海南植胶区4种不同母质分别发育而成的砖红壤土壤有机碳储量均具有明显的垂直分布性,随着土壤深度的增加,有机碳储量逐渐降低。3种方法计算的海南植胶区4种砖红壤0~60 cm土层有机碳储量平均为47.98~59.14 Mg/hm^2,远低于同气候带原始森林土壤有机碳储量。Soil organic carbon storage in rubber plantations in Hainan was calculated by using the fixed depth method, equivalent mass method and vertical fitting method. The results showed that the soil organic carbon storage of latosols derived from four different parent materials in rubber plantation in Hainan was obviously vertically distributed and declined gradually with the depth of soil layer. The soil organic carbon storage of four types of latosol at the soil layers of 0 ~60 cm in rubber plantations in Hainan was approximately 47.98~59.14 Mg/hm^2, which was much less than that in the soil of the primary forests in the same climate zone.
