Soil organic carbon(SOC) is one of the most important constituents of soils due to its capacity in affecting plant growth indirectly and directly. The change of SOC content is associated with organic input with various sources in soil. This study was conducted as follows; the evaluation of the effects of altitude above sea levels on SOC concentration in forest and arable soil under climatic zone, investigation of relationship between SOC contents and temperature in soil with elevation. Under the different climatic zone, the SOC concentration in forest and arable soil was affected by increasing the altitude levels. The SOC concentration of forest soil was higher than that of arable soil regardless of climatic zone. Also, the SOC was dramatically related to the soil temperature with altitude, which was induced the increase of SOC contents in forest and arable soils. These results indicated that the soil temperature with altitude could be differed carbon storage in forest and arable soil between climatic zone.
