中文摘要	选取内蒙古西部的温带森林、温带草原、温带灌丛、温带荒漠和草甸共70个样地,对其土壤有机碳进行研究。结果表明,内蒙古西部不同植被类型的土壤有机碳含量不同,温带森林的固碳效果最好,其次为温带灌丛和草原,再次之为草甸和荒漠。内蒙古西部20cm土壤有机碳储量为11.034 * 10~8 t,100cm土壤有机碳储量为22.062 * 10~8 t,温带草原和荒漠碳储量最高。气候因素对内蒙古西部土壤有机碳含量的影响显著,偏相关分析结果表明气温是主要的影响因子。土壤全氮含量与土壤有机碳含量有明显的线性正相关关系。
英文摘要	In this research,70 plots were surveyed in typical vegetation types of western Inner Mongolia including temperate forest,temperate steppe,temperate shrub,meadow and desert,to study the soil organic carbon and its influencing factors. The results showed that in western Inner Mongolia,soil organic carbon content and density were different in five vegetation types. Among the five vegetation types,the temperate forest had the best effect of carbon sequestration,followed by temperate shrub and temperate steppe,and meadow and desert were placed at the bottom. The total carbon storage in western Inner Mongolia were 11.03 * 10~8 t and 22.062 * 10~8 t. The carbon storages of temperate steppe and desert were much higher than others. Climate factors had significant effects on the soil organic carbon content of western Inner Mongolia,and partial correlation analysis showed that the temperature was the main influencing factor. The soil nitrogen content had obvious linear correlation with the soil organic carbon content.
