摘要：Forests simultaneously provide multiple ecosystem services (ESs), but the trade-off and synergy among them were uncertain. Biotic and abiotic variables regulate forest ecosystem service multifunctionality (EMF); however, quantifying the relative contribution of them to EMF in natural forests at large scale was still limited. We examined the trade-off in ecosystem services and the drivers of EMF of natural temperate forests in northeast China. Six facets of ESs were derived based on 2227 national forest inventory sample plots, that is, water conservation, soil conservation, stand productivity, tree species diversity, carbon storage and soil fertility maintenance. Structural equation model was applied to quantify the driving forces of EMF including mean annual temperature (MAT), mean annual precipitation (MAP), total nitrogen (TN), soil pH (pH), stand age (Age), additive stand density index (aSDI), stand structural diversity (SSD) and tree species richness (SR). Our results indicated that the RMSD (root mean square deviation) values of the 15 ES pairs ranged from 0.13 to 0.25, and the trade-offs between biodiversity and other five ESs were high, with RMSD values greater than 0.2. We provided clear evidence that stand density was the most important driver of EMF, which affected the EMF indirectly through tree size diversity and species richness. Understanding the contribution of these factors to EMF can help to design sustainable forest management practices in northeast China aiming to foster and preserve multifunctionality.
