Abstract

Backgrounds

Grassland ecosystems consist of different grassland types and provide multiple ecosystem services and functions simultaneously. However, the relative importance of plant community characteristics and soil properties in promoting the ecosystem multifunctionality (EMF) among different grassland types is unclear.

Methods

A field study was conducted to investigate the effects of multidimensional plant diversity, plant coverage, and soil properties on EMF in alpine steppe (AS), alpine meadow (AM), and alpine swamp meadow (ASM).

Results

Environmental filtration resulted in a gradual decrease in plant species diversity and Faith’ s phylogenetic diversity (PD) from AS to ASM. Plant species in AM with high functional diversity and mean phylogenetic pairwise distance (MPD). There was no significant difference in EMF among grassland types. Importantly, phylogenetic diversity and plant coverage had a direct positive effect on EMF in AS and AM, respectively. Additionally, soil moisture also played a crucial role in maintaining EMF in AS. Functional richness index (FRic) was positively correlated with EMF, while soil moisture was the key to maintaining EMF in ASM, followed by soil bulk density.

Conclusion

Our research highlighted the importance of plant community characteristics in maintaining the EMF of AS and AM. Additionally, EMF in ASM was mainly regulated by soil properties. We suggest that management measures should be established based on the specific characteristics of each grassland type, which is essential for maintaining ecosystem multifunctionality.

期刊介绍： Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
