摘要(Abstract)：

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:0-10cm和10-20cm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);0-10cm土层土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;10-20cm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植被盖度的线性回归模型。

关键词(KeyWords)： 短花针茅草原;土壤有机碳;植被
