【摘要】 [目的]构建耕地多功能评价指标体系,并在此基础上探究耕地多功能时空演变规律以及各项功能之间的权衡与协同空间分布格局及变化。[方法]运用综合评价法对耕地多功能进行评价,并采用斯皮尔曼相关性分析和空间自相关分析。[结果]2008—2018年安福县耕地生产功能、社会保障、景观休憩功能整体呈下降趋势,生态调节功能持续上升;耕地的生产-景观休憩功能、社会保障-景观休憩功能之间存在显著的协同关系,社会保障-生态调节功能、生态调节-景观休憩功能之间存在显著的权衡关系;安福县耕地各项功能在空间分布上差异明显,其呈现HH协同的区域主要分布在地势较为平缓的安福县东南部平都镇周围,功能分值较低呈现LL协同关系的区域主要分布在安福县西北部地势较高区域。[结论]通过研究耕地多功能时空演变及其协同性,可以有效地促进耕地合理的空间布局以及制定区域耕地利用方针,实现耕地高效可持续利用。更多还原

【Abstract】 [Objective]To construct a multi-functional evaluation index system for cultivated land, and on this basis, to explore the spatial and temporal evolution of cultivated land and the trade-offs and coordination between various functions and the spatial distribution patterns and changes.[Method]Comprehensive evaluation method was used to evaluate the multi-function of cultivated land, and Spearman correlation analysis and spatial autocorrelation analysis were used.[Result]From 2008 to 2018, the production function of cultivated land, social security, and landscape recreational functions in Anfu County showed an overall downward trend, and the ecological regulation function continued to rise. There was a significant synergistic relationship between the production of arable land-landscape rest function, social security-landscape rest function; there was a significant trade-off relationship between social security-ecological adjustment function, ecological adjustment-landscape rest function. The various functions of cultivated land in Anfu County have obvious differences in spatial distribution. The areas showing HH coordination were mainly distributed around Pingdu Town in the southeast of Anfu County, where the terrain was relatively flat, and the areas with lower function scores showing LL synergy relationship were mainly distributed in the higher-lying area in the northwest of Anfu County. [Conclusion]By studying the multi-functional temporal and spatial evolution of cultivated land and its synergy, it can effectively promote the reasonable spatial layout of cultivated land and formulate regional cultivated land use policies to achieve efficient and sustainable use of cultivated land.更多还原
