内蒙古土壤有机碳/氮含量、空间分布及其与主要气候因子的关系研究表明，土壤有机碳、氮含量分别为3.24~43.24 kg.m-3和269.56~3085.60 g.m-3，C/N比约为4.46~17.13。土壤有机碳/氮与温度呈负相关，R分别为0.557和0.460。土壤有机碳/氮与降水量呈弱正相关，R分别为0.285和0.203。土壤有机碳、氮自东北向西南随气温升高、降水减少而呈现减少趋势。
Studies on the amount and spatial distribution of soil organic carbon/nitrogen in Inner Mongolia and their relationship to main climate factors showed that the content of soil organic carbon and nitrogen was 3.24-43.24 kg.m-3 and 269.56-3085.60 g.m-3, respectively, and the C/N ratio was about 4.46-17.13. The correlation between soil organic carbon/nitrogen and temperature was negative, and R was 0.557 and 0.460, respectively. Soil organic carbon/nitrogen had a weak positive correlation to precipitation, and R was 0.285 and 0.203. Soil organic carbon and nitrogen appeared a reducing trend with increasing temperature and decreasing precipitation from northeast to southwest.
