Forest carbon stocks change and silvicultural investment in China – the case of coniferous forests

This paper reports change in forest carbon stocks and their relationship to investment in forestry fixed assets in silviculture in China employing the forest stock volume conversion method for carbon stocks and annual sinks. The paper establishes carbon stock estimates, and then analyses recent carbon stock trends of main coniferous species based on the latest inventory of China’s forest resources. The inventory data cover the seven dominant coniferous species from 1989 to 2008. The paper shows that investment in forestry fixed assets in silviculture and forest carbon stocks of some species have a significant effect with a lag of 3–7 years; and there is discussion of various problems regarding forest carbon stocks and sinks.
