Carbon Storage and Distribution Law of the Rubber Forest Ecological System in Danzhou of Hainan

TLDR: In this paper, the carbon storage in the rubber forest ecological system is mainly made up of the soil, undergrowth vegetation, litter and tree layers, and the organic carbon of samples were indoor tested and analyzed.

Abstract: 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/hm2.The carbon storage of soil layer was 536.9 t/hm2 the carbon storage of tree layer(306.8 t/hm2)the carbon storage of litter layer(4.4 t/hm2) the carbon storage of undergrowth vegetation layer(3.2 t/hm2).The carbon storages in the rubber plantations of different tree ages changed approximately between 75.7 t/hm2 and 152.7 t/hm2,and showed an approximately double peak trend.
