Ecological restoration can effectively boost soil fertility and microbial activity in degraded ecosystems. Yet, its impact on the relationship between soil-specific enzyme activity (SSEA) and microbial necromass carbon in barren sandy soils is still poorly understood. Therefore, we aimed to analyze the effects of ecological restoration on the SSEA per unit of soil organic carbon (SOCE) and SSEA per unit of microbial biomass carbon (MBCE), as well as their correlation with the necromass accumulat
