摘　　要：本研究以甘孜州丹巴地区柏木纯林林下七种植物作为研究对象,对其叶、茎、根部的碳含量进行测定研究。研究结果表明:研究区域碳含量表现为植物叶茎>植物根部>土壤;不同植物叶、茎和根部之间碳含量有显著差异(P<0.05),其中腋花勾儿茶的叶片和茎部的碳含量均显著最高(分别为503.94 g/kg和397.10 g/kg),茵陈蒿的叶片和根部碳含量均最低(分别为212.45 g/kg和251.23 g/kg),毛瑞香茎部碳含量最低(267.62g/kg),橙花瑞香根部碳含量最高(366.73g/kg)。七种典型植物不同部位之间仅有灰毛紫菀、腋花勾儿茶和毛瑞香表现出显著差异,灰毛紫菀表现为植株的根部碳含量显著低于叶、茎部碳含量(P<0.05),腋花勾儿茶表现为植株的叶部碳含量显著高于根、茎部碳含量(P<0.05),毛瑞香表现为植株的茎部碳含量显著低于根、茎部碳含量(P<0.05),其余四种植物无显著差异;整体上看,腋花勾儿茶叶的茎和叶碳含量最高,可能具有较强固碳能力。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.
