摘　　要：橡胶林生态系统碳贮量主要由土壤层、枯枝落叶层、林下植被层和乔木层组成。对海南儋州6个龄级(5、10、15、20、25、30年生)橡胶林样地的土壤层(0cm-20cm,20cm-40cm,40cm-60cm,60cm-80cm,80cm-100cm)、林下植被层、枯枝落叶层和乔木层样品进行了调查、采样,并对其有机碳含量进行室内测试分析,初步探得海南儋州橡胶林生态系统总碳贮量为851.3t/hm2,碳贮量土壤层(536.9t/hm2)>乔木层(306.8t/hm2)>枯枝落叶层(4.4t/hm2)>林下植被(3.2t/hm2)。5、10、15、20、25、30年生橡胶林生态系统碳贮量在(75.7-152.7)t/hm2之间变化,呈"双峰"趋势。The carbon storage in the rubber forest ecological system is mainly made up of the soil,undergrowth vegetation,litter and tree layers.Samples from the soil layer（0 cm-20 cm,20 cm-40 cm,40 cm-60 cm,60 cm-80 cm,80 cm-100 cm）,undergrowth vegetation layer,litter layer and tree（5,10,15,20,25 and 30 years old） layer of the rubber plantation in Danzhou of Hainan were investigated,and the organic carbon of samples were indoor tested and analyzed.It was preliminarily concluded that the carbon storage of rubber forest ecological system in Danzhou of Hainan was 851.3 t/hm^2.The carbon storage of soil layer was 536.9 t/hm^2 〉the carbon storage of tree layer（306.8 t/hm^2）〉the carbon storage of litter layer（4.4 t/hm^2）〉 the carbon storage of undergrowth vegetation layer（3.2 t/hm^2）.The carbon storages in the rubber plantations of different tree ages changed approximately between 75.7 t/hm^2 and 152.7 t/hm^2,and showed an approximately double peak trend.
