| 摘 要： | 火地塘林区地处秦岭南坡中段,是中国暖温带向亚热带气候的过渡带。林区森林主要为天然次生林, 树木种类丰富并具有明显的垂直分异性。准确估算森林碳储量在研究全国乃至全球碳平衡中起着重要的作用。笔者基于生物量的回归方程, 估算该林区主要森林类型碳储量和碳密度的大小，并运用GIS软件Citystar(4.0)进行数据的空间分析。结果显示：不同树种随海拔高度呈垂直地带性分布。华山松和红桦的分布范围广，且碳储量大小明显高于其它三种类型的；锐齿栎、油松主要分布于中低海拔地带；华北落叶松的平均碳密度值最大；锐齿栎和红桦的平均碳密度接近但低于华北落叶松的；油松和华山松的平均碳密度接近且较低。

| Abstract: | Huoditang Forestry Region is on south-facing slope at mid-mountain zones of Qinling Mountains lies in the transition zone form warm temperate to subtropical. There were rich plant species that have distinct elevation steepness characteristic in spatial distribution, and most of them were secondary forests. Accurately estimating forest carbon storage plays an important role in study of national or global carbon budget. In this article, use biomass regression equation of five main forest-types at the Huoditang forestry region to calculate carbon storage and carbon density of these forests, and use GIS computer software Citystar (4.0) to analyze the spatial distribution of forests, carbon storage and carbon density in this area. The results showed that the distribution of forests have different characteristics in different elevation. Pinus armandii and Betula albo-sinensis distributed in all area, and Quercus aliena var. acuteserrat and Pinus tabulaeformis distributed at lower mountain belt. Carbon storage of and Betula albo-sinensis were higher than other three types. Mean carbon density of Larix princepisrupprechtii was highest, Betula albo-sinensis and Quercus aliena var. acuteserrat took second place and the value were almost equal, and Pinus armandii and P. tabulaeformis took third place and the value were almost equal. The spatial distribution of carbon storage and carbon density of forests was consistent with elevation. |
