摘要

The role of temporary ponds in carbon budgets remains poorly understood, particularly in arid regions. This study quantified soil organic carbon (SOC) stocks in 15 temporary ponds in Morocco, across three land use types (agricultural, reserve, forest). In each pond, one soil core was collected in each of the three topographic zone (peripheral, intermediate, and central) and divided in three soil depth (0–15, 15–30, 30–45 cm) with sub-samples (3) averaged by layer. Relationship with vegetation abundance and plant diversity (aquatic and terrestrial), hydrological and soil properties were also assessed. SOC content was measured, and factorial ANOVAs with Tukey’s tests were used for statistical analysis. SOC density was significantly higher in agricultural and reserve ponds than in forest ponds. Total SOC stock was positively correlated with hydrology, soil nutrients, and vegetation attributes, while topographic zone, soil depth, or their interaction showed no significant effects. Extrapolation to all 672 ponds in the 2760 km2 study area estimated a total SOC stock of 153,878 metric tons. These results highlight the importance of conserving agricultural ponds and creating new reserves in pond-rich forest areas to maximize carbon sequestration in semi-arid regions.
