摘要：Mixed planting is becoming an afforestation approach that can actively enhance forest productivity and soil stoichiometry. Understanding the driving factors behind changes in soil stoichiometry in mixed forests is of great significance for maintaining forest ecosystem stability and promoting sustainable development and management of planted forests. However, explaining the trends in soil stoichiometry changes solely based on environmental factors and soil properties lacks comprehensiveness. Phylogeny is closely related to plants, but the influence on soil stoichiometry remains to be verified. Here, we compiled a dataset consisting of 578 field measurements, including soil organic carbon, total nitrogen, available nitrogen, total phosphorus, and available phosphorus, from Pinus massoniana mixed forests with different species. The dataset covers 15 families, 26 genera, and 34 species, aiming to explore the trends in soil stoichiometry changes among Pinus massoniana mixed forests with different species and whether they exhibit phylogenetic signals. Additionally, we investigated the relationship between mixed forests with different species and biotic and abiotic factors, and quantified the relative importance of environmental factors and divergence time in altering soil stoichiometry in Pinus massoniana mixed forests. Our results indicate that the soil total carbon, total nitrogen, and total phosphorus in mixed forests exhibit significant phylogenetic signals, and species distantly positioned on the phylogenetic tree contribute more to the enhancement of soil stoichiometry. Climate factors and soil conditions have been demonstrated to significantly influence the stoichiometry of soil carbon, nitrogen, and phosphorus. According to the relative influence analysis, we found that age of trees and divergence time, similar to environmental factors, have significant impacts on soil stoichiometry in Pinus massoniana mixed forests. This study provides valuable insights for the efficient establishment and application of mixed forests and serves as a theoretical basis for the selection of suitable tree species. ? 2024, The Authors.
