中文摘要	灰榆林是贺兰山保护区面积最大的植被类型,关于其有机碳储量的研究对评价贺兰山自然保护区生态服务功能具有重要意义。对贺兰山东麓灰榆林单株生物量及含碳量、林下生物量及含碳量、土壤有机碳进行了测定,进而估算了灰榆林有机碳储量。结果表明:(1)灰榆各部分含碳率有较大差异。树干含碳率最高,嫩枝叶含碳率最低,平均含碳率为437.78g/kg,低于其他树种的含碳率。林下草本及细根有机碳密度276.61g/m~2。(2)林下土壤含碳率15.82g/kg,有机碳密度3.76kg/m~2;(3)灰榆林平均有机碳密度为4.72kg/m~2,每1hm~2碳储量约为47.2t,土壤碳储量要显著高于植被碳储量。在植被稀疏的干旱区,土壤环境条件有利于有机碳的累积,土壤有机碳是干旱区重要的有机碳库。
英文摘要	The Ulmus glaucescens woodland is the largest vegetation type in the Helan Mountain natural reserve areas.Research on the organic carbon storage of the woodland is useful for evaluating ecological service functions of the area.The biomass,vegetation carbon content and soil organic carbon of the woodland were sampled and measured on the east side of Helan Mountains and the carbon storage was evaluated.The carbon contents varied in the different parts of Ulmus glaucescens.The trunk carbon content rate was higher than other parts and average carbon content of Ulmus glaucescens was 437.78g/kg,lower than other forest species.The carbon density of understory and roots was 276.61g/m~2.The soil carbon content was 15.82g/kg, higher than other soil type,and the carbon density was 3.76kg/m~2.Average organic carbon density of the woodland was 4.72kg/m~2.Carbon storage per hectare was 47.2t.Soil carbon storage was significantly higher than vegetation carbon storage.In the sparsely vegetated arid area,soil conditions are of benefit to the organic carbon accumulation.Soil organic carbon in arid zone is an important organic carbon pool.
