| 摘 要： | 目的 文章以格网为评价尺度精细测算和分析广西边境地区耕地利用“四维度”功能的时空分异及权衡/协同关系，旨在为边疆土地安全科学发展提供思路和方法借鉴。方法 多目标决策法、Spearman秩相关分析法、双变量空间自相关模型、聚类分析方法。结果 （1）2000—2018年耕地利用多功能存在显著空间分布异质性和波动性，耕地的社会保障功能、生态安全功能均呈现减弱后增强态势，而经济生产功能、安全发展功能则逐渐减弱；（2）耕地利用多功能间交互作用大多呈协同关系且程度不一，随时间的推移权衡程度逐渐增强；（3）耕地利用多功能权衡/协同关系空间集聚性突出，协同区大体呈现“多核心”团聚发展格局，权衡区变化相对稳定；（4）根据主导功能及权衡/协同关系将广西边境地区划分为功能协同发展区、功能权衡发展区、生态主导发展区，并提出了具体措施。结论 边境耕地利用多功能应以安全协调可持续发展为导向，划分不同管护区并提出优化建议以提升边境耕地多功能复合利用。

| Abstract: | Taking grid as the evaluation scale, this paper finely calculated and analyzed the temporal and spatial differentiation and trade-off/synergy of the "four-dimensional" function of the utilization of cultivated land in Guangxi border areas, aiming at providing ideas and methods for the safe and scientific development of border land. Multi-objective decision making, Spearman rank correlation analysis, bivariate spatial autocorrelation model and cluster analysis was used in this paper. The results were obtained as follows. (1) There was significant spatial heterogeneity and fluctuation in the multifunction of the utilization of cultivated land from 2000 to 2018. The social security function and ecological security function of cultivated land were weakened and then strengthened, while the functions of economic production and safe development were gradually weakened; (2) The interaction between the multi-functions of the utilization of cultivated land was mostly synergistic and the degree was different, and the trade-off degree was gradually enhanced with time; (3) The spatial agglomeration of the multi-functional trade-off/synergy relationship of the utilization of cultivated land was prominent, the synergy area generally presented a "multi-core" agglomeration development pattern, while the change of the trade-off area was relatively stable; (4) According to the dominant function and trade-off/synergy relationship, the border areas of Guangxi was divided into functional synergy development areas, functional trade-off development areas and ecological dominant development areas, and specific measures were put forward. Therefore, the multi-function utilization of cultivated land in border areas should be safety, coordination and sustainability-oriented, different management and protection areas should be divided, and optimization suggestions should be proposed, so as to enhance the multi-function compound utilization of cultivated land in border areas. |
