Abstract

In this context, this study was carried out in the mountainous area of Zeidon, Bebahan City, to investigate the impact of restoration measures on soil carbon emissions. To achieve this goal, three specific zones were chosen in the study area: a control area without rehabilitation, an area where shrub planting was conducted, and a contour farrow area. In each of these areas, four 100-meter transects were established. Along each transect, measurements of carbon emissions were taken from four designated plots. The sampling process involved the use of alkaline traps and the still-closed chamber method. In order to assess seasonal variations in carbon emissions, measurements were taken during the summer, autumn, and winter seasons. The findings revealed that the amount of carbon emissions from the untreated pasture was significantly greater than those from the areas where bush planting and contour farrow treatments were carried out. The control treatment had the highest carbon emission rate of 1.15 grams per square meter per day, while the planting treatment had the lowest rate of 0.42 grams per square meter per day. No significant difference was observed in carbon emissions between the Shrub and Contour farrow treatments. The study also revealed that carbon emissions were higher in the summer than in the autumn and winter seasons, with an average of 0.9 grams per square meter per day in the summer and 0.55 grams per square meter per day in the winter. There was no significant difference in carbon emissions between seasons in the control treatment. The Shrub planting treatment exhibited a significant difference in carbon emissions between summer and autumn compared to winter. Similarly, in contour farrow, carbon emissions were significantly higher in summer than in autumn and winter.
