    Abstract:

    [Objective] The evolvement characteristics of multifunctional tradeoff and synergistic relationship of cultivated land use were analyzed, and countermeasures and suggestions for regional optimization were put forward, in order to provide support for ensuring food security and promoting sustainable use of regional cultivated land. [Methods] Partial correlation analysis and spatial autocorrelation analysis were used to determine the spatiotemporal evolution characteristics of multifunctional trade-offs and collaborative relationships among cultivated land, and the systematic clustering method was used to partition cultivated land functions. [Results] ① During the study period, the production function of farmland in the Great Nanchang metropolitan area increased, the overall social security function decreased, and the ecological function showed a fluctuating upward trend, with little change in the landscape aesthetic function. ② The synergistic relationship between the production function of arable land and the social security function weakened over time, mainly in the eastern and southern parts of the study area. The production function and ecological function showed a balanced relationship, and the balance intensity also weakened over time, mainly in the western part of the study area. ③ Cultivated land in the study area was divided into four functional zones, among which the leading production zone should promote the centralized and large-scale management of the leading industrial production areas. The leading landscape-oriented area should develop leisure and sightseeing agriculture to achieve integrated development of agriculture and tourism. The leading ecological area should focus on green ecological agriculture and create standardized production bases. The balanced development zone had no obvious advantageous functions and could serve as a potential supplementary area for arable land functions. [Conclusion] These study results revealed the multifunctional trade-offs and synergy of cultivated land use in the Great Nanchang metropolitan area. The study area was divided into different types of areas, and suggestions were put forward for differentiated utilization of cultivated land, and therefore to provide decision-making support for giving full attention to the advantages of cultivated land in each region, making up for functional shortcomings, and promoting the diversification of cultivated land functions.
