Distribution characteristics of soil organic carbon density of different forests in Huanghuadianzi watershed
[Objective] This study analyzed the distribution characteristics of soil organic carbon (SOC) density in different plantations in Huanghuadianzi watershed to provide theoretical basis for management of carbon sink in plantation ecosystem.[Method] Four different forest plantations,Prunus sibirica × Pinus tabulae formis,Prunus sibirica,Populus simonii and Caragana intermedia in Huanghuadianzi watershed,Aohan,Chifeng of Inner Mongolia were selected to investigate the distribution characteristics of SOC density at the depth of 0-100 cm.[Result] Average density of SOC in four forest types was 0.85-1.07 kg/m2.SOC density of mixed forest was significantly higher than that of pure forest,and SOC density of arbor forest was significantly higher than that of shrub forest.SOC mainly accumulated in the depth of 0-20 cm and it decreased significantly with the increase of soil depth.[Conclusion] It is suggested to increase the planting area of mixed forest and reduce the effects of human activities on disturbance and destruction of forest soil.
