英文摘要	There is a growing body of knowledge that ecosystem functions, in particular, soil-based ecosystem functions, are related to biodiversity. However, how plant species diversity influences soil-based functions along post-agricultural secondary succession is still a largely ignored question in Mediterranean semi-arid conditions. Therefore, we used the plant functional group approach to investigate the relationships between plant species diversity indices and soil-based functions including microbial biomass carbon (MBC), basal respiration (BR), and carbon sequestration (CS) across three different stages of the vegetation succession corresponding to similar to 5 years after agricultural abandonment, similar to 15 years after abandonment, and oak forests which represent the terminal stage. We also tested if these relationships are supported by the niche complementarity and selection effect hypotheses. The results showed that soil-based functions significantly increased with time since abandonment as BR, MBC, and CS increased respectively by 1.7, 1.5, and 2.7 times across the three successional stages. We also found strong correlations between the diversity indices and the soil-based functions BR, MBC, and CS which were positive for richness (R(2)values 0.75, 0.74, and 0.75) and Shannon diversity (R(2)values 0.61, 0.58, and 0.61) but negative for evenness (R(2)values 0.38, 0.38, and 0.36 for, respectively). Similarly, richness and Shannon diversity of the different plant functional groups positively correlated with soil-based functions. However, contrasting results were found for evenness which positively correlated with soil-based functions for perennial grass only. We suggested that increasing the diversity of plant species and facilitating dominant species would be needed to improve the soil-based ecosystem functions after abandonment of degraded soils. This study also revealed that the mechanisms behind the relationships between biodiversity and ecosystem functions were influenced by the vegetative forms.
