Abstract: Trade-offs in cultivated land multifunctionality are often required to determine how cultivated land protection can evolve from single-purpose food production toward a coordinated land system. This study aims to review research progress on the trade-offs in cultivated land multifunctionality. A framework was then developed to cover conceptual interpretation, identification and measurement, driving mechanisms, and governance pathways. Existing studies were compared to examine agricultural multifunctionality, land-use multifunctionality, ecosystem services, landscape functions, cultivated land protection, and territorial spatial governance. Finally, a systematic summary was given in terms of conceptual focus, functional classification, measurement approaches, research perspectives, explanatory mechanisms, and policy responses. It was found that cultivated land multifunctionality referred to the cultivated land with multiple products, services, and values, including food production, ecological regulation, landscape culture, livelihood support, and social security. Trade-offs were used to describe the competition, substitution, or mutual restriction among these functions under limited resources, according to the differentiated land-use practices and social demands. Cultivated land multifunctionality trade-offs were characterized by the semi-natural and semi-artificial attributes of cultivated land, as well as its combined production, ecological, economic, and social roles, compared with ecosystem service trade-offs. Three perspectives were developed in the current research. Supply-side studies focused on resource endowments, land-use intensity, spatial patterns, and practices for multifunctional outputs. Demand-side studies examined how farmers, residents, governments, and other stakeholders differed in their functional preferences and land-use decisions. Furthermore, supply-demand coupling studies were used to clarify functional gaps, spatial mismatch, and coordination between functional provision and social demand. The weak connection also remained in the cultivated land multifunctionality trade-offs. In terms of measurement, indicator systems were integrated to assess cultivated land multifunctionality due to their operational, flexible, and suitable nature for spatial comparison. Ecosystem service models, landscape pattern indices, monetary valuation, and emergy analysis were increasingly used to assess ecological representation, spatial structure, value comparability, and system-level efficiency. Trade-offs were identified, including coordination degree models, grey relational analysis, polygon graphics, hot spot analysis, spatial autocorrelation, correlation analysis, social network analysis, mechanical equilibrium models, convergence analysis, trade-off degree models, and spatial mismatch indices. The shift was promoted from functional assessment to relationship analysis. Most existing studies emphasized static correlation, coordination status, or spatial co-occurrence. It was also limited in explaining the trade-off direction, temporal evolution, cross-scale transmission, uncertainty, and causal mechanisms. The cultivated land multifunctionality trade-offs were then formed to shape the interaction of natural endowments, stakeholder preferences, and external environmental factors. Among them, natural conditions were selected to define the supply boundary and functional potential of cultivated land. Stakeholder preferences also posed great influence on land-use choices and functional priorities. Multifunctionality trade-offs were regulated to balance institutions, markets, urbanization, industrialization, demographic change, and policy instruments using incentives, constraints, and resource allocation. Four pathways were proposed for existing governance studies: zoning with functional differentiation, spatial pattern optimization, compensation to coordinate stakeholder interests, and technology-driven land use transformation. These pathways provided practical tools to reduce functional conflicts, but they were often considered separately. It was often required for their links with trade-off diagnosis, driving mechanisms, and adaptive feedback. Overall, cultivated land multifunctionality trade-offs were shifted from function classification and static evaluation to mechanism explanation and governance exploration. Future studies should strengthen theoretical integration, dynamic measurements, and involve various stakeholders. Governance frameworks can be expected to combine spatial optimization, policy regulation, economic incentives, ecological compensation, and technological innovation.
