中文摘要	以艾比湖湿地两种植被类型覆盖下的土壤为研究对象,运用野外采样、室内分析等方法测试并计算灌木荒漠、小乔木荒漠两种植被类型土壤5个土层深度土壤碳蓄积量。研究结果显示:土壤有机碳含量的分布规律高低次序为小乔木荒漠大于灌木荒漠,小乔木荒漠有机碳含量最高值为19.44 g·kg~(-1),灌木荒漠有机碳含量最高值为8.11 g·kg~(-1)。土壤有机碳含量最高值均出现在土壤表层(0~20 cm),土壤有机碳密度表现为土壤表层(0~20 cm)最高(灌木荒漠为2.48 kg·m~(-2),小乔木荒漠为6.37 kg·m~(-2))。土壤有机碳蓄积量计算结果为:灌木荒漠、小乔木荒漠植被覆盖下土壤碳蓄积量分别为344 856.23、3 743 517.41 kg,小乔木荒漠土壤碳蓄积能力高于灌木荒漠土壤碳蓄积能力。上述研究可对干旱区湿地土壤碳循环、艾比湖湿地生态修复等提供科学参考。
英文摘要	This research take in wetland soil covered by two different plants in the Ebinur Lake as the research object. By theways field sampling and laboratory analysis, we tested the soil covered by desert shrubs and microphanerophytes desert shrubs and calculated the carbon stock volume in 5 different soil layers. The results show that the soil carbon content in microphanerophytes desert is 19.44 g·kg~(-1) which is much higher than that in shrub desert, themaximum content of carbon in the shrub desert. The peak organic carbon content occurs in the soil’s surface layer(0~20 cm), and the maximum organic carbon density also is presentedin the soil’s surface layer(0~20 cm). Soil in shrubs desert is 2.48 kg·m~(-2), soil in microphanerophytes desert is 6.37 kg·m~(-2). The calculation of soil accumulate stock volume of organic carbon show that the carbon accumulation, soil in desert shrubs is 344 856.23 kg, and which is 3 743 517.41 kg in microphanerophytes desert. Soil carbon acumulationed ability in the microphanerophytes desert is higher than the shrub desert. This research can provide scientific reference for soil carbon cycle in arid wetland region and ecological restoration of Ebinur lake.
