Abstract: Aims Comprehensively understanding the formation mechanism of ecosystem services is a prerequisite for maintaining the sustainable supply of ecosystem services. Plant functional traits directly participate in a variety of ecosystem processes, which in turn affect the supply of ecosystem services. Revealing the relationship between plant functional traits and ecosystem services is an important way to understand the formation mechanism of ecosystem services. Methods Using a systematic literature review method, 86 papers on plant functional properties and ecosystem services were retrieved in the Web of Science database, 466 pairs of plant functional traits and ecosystem services, and 83 plant functional traits were counted. The research characteristics of the relationship between plant functional traits and ecosystem services were revealed, as well as the main plant functional traits that affect different ecosystem services and their impact mechanisms. Important findings The results show that the research on the relationship between plant functional traits and ecosystem services focuses on natural ecosystems such as grasslands and forests. Most of which focused on ecosystem products to provide services and support services, including biomass, net primary productivity, and soil organic carbon. Based on the impacts of plant functional traits on different ecosystem services, the plant functional traits can be clustered into five categories: soil-conservation-related traits, water-cycle-related traits, ecosystem-multifunction-related traits, product-providing-related traits, and pollination-biocontrol-related traits. The uncertainty of climate change and human activities, and differences in spatial and temporal scales on the relationship between plant functional traits and ecosystem services need to be further explored.
