山东省森林碳储量调查研究

森林作为陆地上的重要碳库,在调节气候,吸收大气中的二氧化碳,降低温室气体浓度等方面发挥着巨大的作用。山东省于2013年结合全国林业碳汇计量监测体系建设,开展了山东省森林碳汇专项调查,主要针对地上、地下、枯死木、枯落物和土壤5个碳库展开调查。共设置194个调查样地,经调查计算发现:山东省森林碳储量总量呈现逐年增加态势,至2012年,全省森林碳储量达到10524.85万t;在各碳库所占比重中,乔木层碳储量比重最大,其次为土壤碳储量,枯死木所占比重最小;除土壤碳库稳定不变,疏林碳储量呈现减少趋势外,其余碳库均呈现逐年增加趋势。

The research of forest carbon storage in Shandong province

Forest land as an important carbon pools, in regulating climate, absorbing carbon dioxide from the atmosphere, reduce concentrations of greenhouse gases, and so on, play an enormous role. Shandong province in 2013 with the national forestry carbon sequestration measurement monitoring system, carry out the forest carbon sinks special investigation in Shandong province, mainly on the ground, underground, dead woods, litter and soil five carbon pools. To set up 194 survey samples, after investigation and calculation found： Shandong province forest carbon trend increases year by year, total to 2012, the province＇s forest carbon reserves of 10524.85 million tons; In various carbon storage proportion of tree layer carbon proportion is the largest, followed by soil carbon reserves, dead woods for a minimum proportion~ In addition to the stable soil carbon library, open forest carbon showed a trend of decrease, the remaining carbon library all showed a trend of increase year by year.
