摘　　要：为平顶山市森林碳汇功能评估和可持续经营提供科学依据,利用平顶山市第七次(2004-2008年)森林资源清查数据,采用材积源生物量法,研究该市森林植被碳储量和碳密度的变化特征。结果表明:平顶山市乔木林总碳储量为417.85万t,平均碳密度为22.89t/hm2,人工林碳储量占87%,天然林碳储量占13%。幼龄林碳储量占67%,成熟林与过成熟林碳储量比例仅占5%;各县(市、区)森林碳储量地理分布格局与森林面积和蓄积的分布一致,鲁山县森林碳储量最大,占平顶山市总碳储量的67.61%,而平顶山市辖区森林碳储量较小。The variation characteristics of forest carbon storage and carbon density was analyzed by the volume-derived biomass based on the forest inventory data in Pingdingshan City（2004-2008）to provide the scientific basis for evaluation and sustainable management of forest carbon sink function in Pingdingshan City.Results：Total carbon storage of arbor forests is 4.1785 millions t and its average carbon density is 22.89t/hm2.The carbon storage of planted forest and natural forest is 87% and 13%respectively.The carbon storage of young forest,immature forest,near-mature forest,mature forest and over-mature forest accounts for 67%,17%,11%,4% and 1% separately.The geographical distribution pattern of forest carbon storage of different counties（cities and districts）is consistent with distribution of forest area and forest accumulation.The forest storage in Lushan County is the maximum,accounts for67.61% of total forest carbon storage in Pingdingshan City and the forest storage in Pingdingshan urban District is 0.2%～0.5% only.
