湖北省太子山森林植被碳密度及碳储量研究

以湖北省太子山林场管理局2009年森林二类清查数据资料为基础,运用生物量转换因子连续函数法,从森林类型、林龄和林分起源角度,对该区域森林植被碳储量和碳密度进行估测.研究表明：湖北省太子山林管局森林植被碳储量为233855.66 t,平均植被碳密度为39.31 t·hm^－2.人工林碳储量高于天然林4．02倍,该区域森林植被碳储量主要由人工林提供.按森林类型划分,不同森林类型碳储量和碳密度均表现为针叶林＞阔叶林＞针阔混交林；按林龄划分森林碳储量,幼龄林＞成熟林＞中龄林＞近熟林＞过熟林,各林龄碳密度随林龄的增加表现为先增加后降低的趋势,中幼林森林面积和碳储量所占比例较大,该区域森林植被碳储量潜力巨大.

Study on Carbon Density and Carbon Storage of Forest Vegetation in Taizi Mountain of Hubei Province

Abstract:From the perspectives of forest type,stand age and stand origin, biomass expansion factor was used to evaluate the carbon storage and carbon density of forest vegetation in Taizi Mountain Forest Management Bureau of Hubei Province,based on the data of forest resource inventory in 2009.The results showed that the carbon storage of forest vegetation was 233 855.66 t,and the average carbon density was 39.31 t·hm-2.Carbon storage of artificial forest was 4.02 times higher than that of natural forest, and forest vegetation carbon storage was provided mainly by artificial forest. According to the type of forest,the carbon storage and carbon density of coniferous forest was the highest, followed by broad leaved forest and coniferous and broad leaved mixed forest.According to the stand age,the carbon storage of young forest was the highest, followed by mature forest, middle aged forest,pre mature forest and over mature forest. The changing trend of forest carbon density was first increasing and then decreasing with the increasing of stand age. The forest area and carbon storage of middle aged and young forest accounted for a larger proportion, and the potential of forest vegetation carbon storage of this area was great.
