摘　　要：基于2010—2021年河北省县域数据,运用当量因子法对河北省耕地生态价值进行核算,并通过三维核密度估计法探究其分布动态与地区差异。研究结果显示:①经测算得知,河北省1个标准单位的修正耕地生态价值当量因子值约为2192.74元/hm^(2)。研究期内耕地生态价值总量呈现波动上升的趋势,且南部>中部>北部。②整体来看,河北省耕地生态价值时空分布不均衡,现处于低位攀升的态势;各地绝对差异缩小,核心地区对整体的带动作用日趋强劲。分区域来看,呈现差异性与趋同性并存的复杂发展特征。③南部地区与各地区高值县域作为主要贡献区和核心地区,可以发挥对区域的协同带动作用。完善区域耕地生态价值评价,探索其时空演变规律,成为河北省加快耕地生态文明建设、探索乡村振兴路径的重要任务。Based on the county data of Hebei Province from 2010 to 2021,this paper utilizes the equivalent factor method to account for the ecological value of cultivated land in Hebei Province,and explores its distribution dynamics and regional differences through the three-dimensional kernel density estimation method.The results of the study show that:①It was calculated that the revised ecological value equivalent factor value of arable land for 1 standard unit in Hebei Province is about 2192.74 yuan/hm^(2).The total ecological value of arable land in the study period shows a fluctuating upward trend,with the value in the south>central>northern.②As a whole,the spatial and temporal distribution of the ecological value of cultivated land in Hebei Province is not balanced,showing a low but rising trend;the absolute differences between the regions are narrowing,and the core region is increasingly strong in driving the overall role.Sub-regionally,complex developmental features with coexistence of differences and convergence are observed.③The southern region and the high-value counties in each region can play a synergistic role in driving the region as the main contributing area and core area.Enhancing the evaluation of regional ecological value in cultivated lands and investigating their spatiotemporal evolution patterns have emerged as critical scientific foundations for advancing the ecological civilization construction in agricultural areas and exploring rural revitalization strategies in Hebei Province.
