- Abstract:
-
Artificial forest is considered as an important approach to enhance terrestrial carbon sink.Soil organic carbon content and density in artificial pine(Pinus massoniana) forest was investigated in Sichuan,employing the method of forest soil carbon inventory.The content and density of soil organic carbon in the artificial forest both decreased with soil depth,and the soil organic carbon density carried with the subregion,showed the ranked order of low-mountain area(150.9±13.3) Mg/hm2 >hilly area(101.4±6.2) Mg/hm2 >western plain area(87.4±5.7) Mg/hm2.Soil organic carbon density was positively and significantly correlated with precipitation and negatively with temperature,respectively.Soil organic carbon density varied also with different management measures and reasonable thinning could increase soil carbon density from(81.7±9.4) Mg/hm2 to(125.8±9.9) Mg/hm2 in hilly area.The management of artificial forest would play a positive role in increasing the forest soil carbon sink and mitigating the global change.
