پیامدهای تغییر اقلیم بر ذخیره کربن خاک در توده های جنگلی بلوط ایرانی

In this research, the status of soil carbon storage in Iranian oak forest stands was monitored during the years 1398 to 1400. For this purpose, two research sites of one hectare were selected in the northern and southern slopes of Dalab forest area in the north of Ilam province. To estimate the soil carbon stock in each research site, 5 soil samples were taken regularly from a depth of 0-30 cm and were taken to the laboratory to measure the percentage of organic carbon, apparent specific gravity and percentage of gravel. Soil samples were collected every year for three years in the middle of the summer season. After three years of data collection, the trend of time changes of soil carbon storage in each site was investigated and this situation was compared among the sites. The amount of soil carbon storage was higher in the northern site in 2018, but it was higher in the southern site in 2019 and 2018. Also, the temporal changes of the amount of carbon storage in both sites showed an increasing trend during the years 1398 to 1400.
