| 摘 要： | 利用鄂伦春自治旗东部主要耕地区1：25万土地质量地球化学调查数据，查明了研究区内表层和深层土壤有机碳储量和有机碳密度分布特征，分析了研究区内土壤有机碳储量、有机碳密度与土壤类型、土地利用方式之间的关系，探讨了土壤类型和土地利用方式对土壤有机碳的作用机理.结果表明研究区内土壤有机碳含量分布不均，土壤类型和土地利用方式是土壤有机碳储量和有机碳密度的主要影响因素.

| Abstract: | Based on the 1:250 000 land quality geochemical survey data of the main cultivated lands in eastern Oroqen Qi, Inner Mongolia, the paper ascertains the organic carbon storage in surface and deep soils and distribution characteristics of organic carbon density in the study area, analyzes the relation of soil organic carbon storage and density to soil type and land use pattern, and discusses the effect mechanism of soil type and land use pattern on soil organic carbon. The results show that the soil organic carbon is unevenly distributed, with soil type and land use pattern as the main factors affecting soil organic carbon storage and density. |
