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.
