薄山林场森林生态系统碳储量与碳密度动态研究

基于1987-2007年3次森林资源清查数据，运用材积源生物量法对河南省驻马店市薄山林场森林生态系统的碳储量进行测算。结果表明，1987-2007年，薄山林场森林植被总的碳储量从421304．99 t增加到636843．53 t，林分碳密度从94．09 t／hm2增加至113．51 t／hm2，碳储量增加明显；乔木层平均碳密度在2007年达到33．90 t／hm2，高于河南省整体水平，接近于全国水平；薄山林场森林生态系统的碳汇贡献最大的主要是近熟林、成熟林与过熟林，但潜力在于中龄林与近熟林。

Dynamic and Density of Carbon Storage in Forest Ecosystem in Boshan National Forest Farm

Base on the forest resource inventory data from 1987 to 2007,using volume-derived biomass method, the paper calculated the forest ecosystem carbon storage in Boshan National Forest Farm,Zhumadian City,Henan Province.The result showed that from 1989 to 2007,the total forest ecosystem carbon stored had increased from 421 304.99 t to 636 843.53 t,the carbon density had increased from 94.09 t/hm2 to 113.51 t/hm2,carbon storage increased significantly.The average of carbon density of tree layer in 2007 is 33.90 t/hm2 ,which was higher than the average level of Henan Province and near to that of national.The largest contributors to forest ecosystem carbon‘sink’function in Boshan National Forest Farm was near mature forest,matures forest and over mature forest,but as for the ‘sink’potential,was in the middle aged forest and near mature forest.
