Abstract:: Based on the investigation data and laboratory experiment, the influence of slope aspects to carbon storage and its spatial distribution had been examined in Pinus sylvestris artificial forest. According to the measurement, the forest carbon density of interdune was much higher than leeward and windward, and the order of its organ carbon density was trunk, root, brunch and leaf. In addition, more carbon assimilation was distributed in trunk growth in interdune and leeward, while root got more carbon in windward, which showed that aspect had the effect on organ carbon distribution. There was not obvious difference between leeward and windward in litter carbon density, leeward was significantly lower than interdune. Moreover, the same results were obtained in whole soil profile. Under every part carbon storage in land, the order of total carbon density was interdune(98.86 t/hm²), leeward(72.3 t/hm²), windward(51.2 t/hm²), the litter carbon storage accounted for 2.8% to 3.1% of total carbon. The soil carbon density accounting for stand carbon density in leeward and interdune were lesser than windward, but it was opposite in forest carbon density, which reflected that stand carbon distribution was affected by slope significantly.
