以黑龙江省大兴安岭地区落叶松天然林为研究对象，利用65株生物量样木的含碳率测定数据，以及2005-2010年复测的285块固定样地数据，采用克里格（ Kriging）插值法，基于ArcGIS平台分析了该地区落叶松林碳密度及其空间分布特征。研究结果表明：落叶松林碳密度的变化范围为1．2～101．1 t/hm2，平均值为37．0 t/hm2。落叶松林乔木（全树）、地上（干、枝、叶）和地下（根）部分碳密度在海拔901～1100 m内最大；落叶松林碳密度在不同坡位上的分布规律从大到小顺序为：上坡、脊、中坡、下坡、谷、平地。落叶松林各部分碳密度在斜坡（坡度15°～24°）最大，乔木和地上部分在平坡（坡度＜5°）最小，而地下部分在陡坡（坡度25°～34°）时最小；落叶松林碳密度在不同坡向上的分布规律从大到小顺序为：阳坡、无坡向、半阴坡、半阳坡、阴坡。大兴安岭地区落叶松林年平均固碳量为1．05 t· hm-2· a-1，其中地上部分年平均固碳量为0．81 t· hm-2· a-1，地下部分年平均固碳量为0．24 t· hm-2· a-1。

With the data of carbon content rates for 65 biomass sample trees and 285 permanent sample plots from natural larch forest of 2005-2010 in the Daxing’an Mountain of Heilongjiang Province, we measured the carbon density and spatial dis-tribution for Larch forests by Kriging spatial interpolation and ArcGIS spatial analysis.The carbon density of larch forest is 1.2 t/hm2-101.1 t/hm2 with the mean of 37.0 t/hm2 .The forest carbon density of total tree, aboveground, and under-ground (roots) reaches the maximum at 901-1 100 m asl.The distribution of the carbon density for larch forest at different slope position is uphill>ridge>middle>downhill>valley>flat.The maximum of carbon density for three part is at the slope of 15°-24°and the maximum is at <5°for total tree and aboveground, and 25°-34°for underground.The distribution at different slope aspect is sunny-slope>none>half shady-slope>half sunny-slope>shady-slope.In the Daxing’ an Mountain, the mean carbon sequestration of larch forest per year for total tree, aboveground and underground are 1.05, 0.81 and 0.24 t/hm2 , respectively .
