中文摘要	研究了荒漠草原土壤有机碳的特征及其与植被之间的关系。结果表明：010cm和1020cm土层土壤有机碳含量随着放牧强度的增加而降低，未放牧区（CK）〉轻度放牧区（LG）〉中度放牧区（MG）〉重度放牧区（HG），中度放牧区和重度放牧区分别显著低于未放牧区（P〈0．05）；010cm土层十壤有机碳含量与草地地上生物量和植被盖度具有极强的相关性，与草群高度具有较强的相关性；1020cm土层土壤有机碳与草地地上生物量和植被盖度具有极强的相关性，而与草群高度的相关性较弱；根据相关性的强弱，建立了土壤有机碳与草地地上生物量和博被盖度的线性回归模型。
英文摘要	The characteristics of Soil organic carbon （SOC） and relationships between SOC and vegetations in desert steppe under different grazing gradients were studied. Results indicated that SOC in the 0 - 10cm and 10 -20cm layers declined with a increased grazing gradients： CK 〉 LG 〉 MG 〉 HG, There is significant different between MG or HG and CK （ P 〈 0. 05）. The correlated analysis indicated that SOC in the 0 - 10cm layer was greater correlated with above -ground biomass and vegetation coverage, while it was greatly correlated with community hight; SOC in the 10 -20cm layer was also greatly correlated with above -ground biomass and vegetation coverage, while it was weakly correlated with community hight; The most important factors affecing SOC in the 0 - 10cm and 10 -20cm soil layers were above -ground biomass and vegetation coverage, regression models between the vegetations and SOC in desert steppe were established
