[Objective] The aims of this study are to explore the characteristics of cultivated land production, life and ecological function utilization, and propose the optimization schemes which are conducive to promoting the multifunctional utilization and coordinated development of cultivated land resources, and promoting the implementation of national cultivated land utilization and protection strategies. [Methods] After clarifying the internal logic of multifunctional utilization of cultivated land, the comprehensive evaluation and spatial pattern of multi-functional cultivated land in 59 districts and counties in the Guangxi section of the Pearl River-Xijiang River Economic Belt were discussed. Finally, based on the trade-off/synergistic correlation between the two functions, the triangular coordinate diagram was used to layout the functional types of cultivated land. [Results](1)From 2000 to 2020, the functional indexes of cultivated land in Guangxi section of the economic belt showed a U-shape with time, and the production function decreased from 0.168 to 0.130. The overall change rate deceased in the order: ecological function(22.62%)>living function(16.94%)>ecological function(15.83%).(2)In the past 20 years, the production, living and ecological functions of cultivated land generally had shown the distribution characteristics of high level in the east and low level in the west, with the proportion of high value areas of production function decreasing to 18.64%, and the proportion of high value areas of living function and ecological function increasing to 27.06% and 28.24%, respectively.(3)Based on the trade-off/synergy relationship between functions, the multifunctional utilization of cultivated land in the study area was divided into four types by using the triangular coordinate diagram method. Among them, the coordinated development area of production-living-ecological function accounted for the largest number of districts and counties, and the multifunctional utilization of cultivated land in the study area performed well as a whole. [Conclusion] The differentiated optimization strategy based on functional evaluation and zoning is conducive to promoting the sustainable utilization and management of regional cultivated land resources, ensuring food security and promoting the development of agricultural modernization.
