Study on Environmental Materials with the Influence of Soil Carbon of Temperate Forests along an Altitude Gradient

Abstract:

Forests cover 30% of global land area and maintain 73% of global soil carbon which is important to the global carbon cycle. In forest ecosystem, climate was expected to affect the quality and quantity of environmental materials (detritus) inputs to soil and soil chemical and physical processes which then affected carbon storage technically. Thus, altitude provided a wonderful site for this environmental research. We collected five soils along the altitudinal gradient on the Changbai Mountain in the North Temperate Zone to analyze the soil properties and carbon content. The results showed the highest SOC content was observed at lowest altitude for the larger plants residues (environmental materials). Except the lowest altitude, the amount of SOC increased with altitude for the low decomposition under the cold temperature. Multiple environmental factors (such as soil type, topography and vegetation) were thought to regulate SOC technically.
