以大岭山森林公园植被为研究对象,根据森林植被生物量及碳储量估算方法,估测样地的植被碳储量,采用反距离加权插值模型,得到整个大岭山森林公园植被碳储量分布情况,运用GIS空间分析方法,结合坡向、坡度、海拔及优势树种等因素对碳储量的空间分异特征进行研究。结果表明:大岭山森林公园植被碳储量随经度的增加而增加,随海拔的升高而增加,在海拔200 m达到最大值,之后随着海拔上升而减少;碳储量随坡度等级的变化近似于正态变化规律,由平坡到斜坡碳储量呈上升趋势,而后由斜坡到急坡逐渐下降;7种优势树种中,速相思、荔枝碳储量含量最高,桉树、硬阔混交林次之,马尾松、灌木、阔叶混交林最少。桉树、速相思在海拔100~200 m、阳坡、斜坡和缓坡的立地条件下,碳储量最大;荔枝在海拔0~200 m、缓坡的立地条件下碳储量最大;硬阔混交林、马尾松、阔叶混交林在海拔100~200 m、缓坡的立地条件下碳储量最大;灌木在海拔200~300 m、斜坡的立地条件下,碳储量最大。
The vegetation in Dalingshan Forest Park was taken as the research object. According to the methods of forest biomass and carbon reserves estimation, the vegetation carbon storage of the sample plots was estimated and the inverse distance weighted interpolation model was used to get the distribution of vegetation carbon storage in the entire Daling Shan Forest Park , Spatial heterogeneity of carbon storage was studied by using GIS spatial analysis method combined with factors such as aspect, slope, elevation and dominant tree species. The results showed that: The vegetation carbon storage in Dalingshan Forest Park increased with the increase of longitude, increased with the elevation, reached the maximum at 200 m altitude and then decreased with the elevation; The change of carbon storage with slope grade was similar Among the seven dominant tree species, the carbon content of Acacia and Lychee was the highest, while that of eucalyptus and broadleaved and broad-leaved forests was the second, Masson pine, shrubs, broadleaf mixed forest at least. Eucalyptus and Acacia acuminata had the highest carbon storage under the site conditions of sunny slopes, slopes and gentle slopes at 100 ~ 200 m above sea level. The longest carbon storage was found on the slopes of 0 ~ 200 m, , The broad-leaved mixed forest at the elevation of 100 ~ 200 m, the largest under the site conditions of gentle slope carbon storage; shrubs at 200 ~ 300 m above sea level, slope site conditions, the largest carbon storage.
