Investigation and comparison of carbon sequestration with regard to, biological operations In the two regions Rimele Khorramabad and Abkandari Koohdasht

The Earth's climate change, caused by greenhouse gases due to the expanding the use of fossil fuels, destruction of vegetation and soil degradation , is the most serious threat to sustainable development and food security, especially in arid and semi-arid regions of the world such as Iran.Carbon sequestration in vegetation ecosystems through management methods like biological operations is an important strategy to deal with this problem.This research was aimed to compare the amount of carbon sequestration resulting from biological operations in two catchments: Rimele and Abkhandari, Khoram Abad province. Sampling was carried out along the transects and within the plots. Then, samples were dried and weighted in plots and hectare. The amount of carbon sequestration was determined per unit area. According to the obtained results, the highest and lowest carbon sequestration were recorded for the Rimele catchment (1604 kg/ ha) and Abkhandari catchment (122 kg/ ha), respectively. In addition, significant differences were found for carbon sequestration between the study sites.
