title: [Spatial characteristics of soil organic carbon and nitrogen in inner Mongolia].
abstract: 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.
