The carbon content of leaves,stems and roots of seven plants under the pure cypress forest in Danba area of Ganzi Prefecture was studied.The results showed that the carbon content in the study area was plant leaf stem>plant root>soil.There were significant differences in carbon content among different plant leaves,stems and roots(P<0.05).Among them,the carbon content of leaves and stems of Axillary Catechu was significantly the highest(503.94 g/kg and 397.10 g/kg,respectively),the carbon content of leaves and roots of Artemisia capillaris was the lowest(212.45 g/kg and 251.23 g/kg,respectively),the carbon content of stems of Daphne odora was the lowest(267.62 g/kg),and the carbon content of roots of Daphne odora was the highest(366.73 g/kg).Among the different parts of the seven typical plants,only Aster cinerascens,Catechus axillaris and Daphne giraldii showed significant differences.Aster cinerascens showed that the carbon content of roots was significantly lower than that of leaves and stems(P<0.05).Catechus axillaris showed that the carbon content of leaves was significantly higher than that of roots and stems(P<0.05).Daphne giraldii showed that the carbon content of stems was significantly lower than that of roots and stems(P<0.05).There was no significant difference among the other four plants.On the whole,the stem and leaf carbon content of the tea leaves is the highest,which may have strong carbon sequestration ability.
