摘　　要：【目的】评价陕西省土地利用与粮食产能的耦合协调程度,并分析其空间分布特征和时空变化趋势。【方法】构建土地利用与粮食产能耦合协调性评价指标体系,采用改进熵值法和耦合协调模型进行分析。【结果】时序分析显示,研究区土地利用与粮食产能耦合度上升,长期高耦合;协调发展度平缓,初级协调;土地利用值下降,粮食产能值上升。空间分析显示,耦合度普遍高,少数地市低或拮抗,分布集中,演化显著。协调度多在中级,陕西省协调度偏低,以省会为中心,空间差异显著。【结论】陕西省土地利用与粮食产能耦合协调关系复杂多变,建议优化土地结构,实施差异化管理策略。[Purposes]This paper aims to evaluate the degree of coupling and coordination between land use and food production capacity in Shaanxi Province,and to analyse its spatial distribution characteristics and spatio-temporal trends.[Methods]This paper construct the evaluation index system of coupling coordination between land use and food production capacity,and uses the improved entropy value method and the coupling coordination model.[Findings]Time-series analysis showed that the coupling degree of land use and food production capacity in the study area rose,with high coupling in the long term;the degree of coordinated development was flat,with primary coordination;the value of land use declined,and the value of food production capacity rose.Spatial analysis shows that the coupling degree is generally high,a few municipalities are in the low-level coupling phase or antagonistic phase,the distribution is concentrated and the evolution is significant.The degree of coordination is mostly at the intermediate coordination level,with low coordination in Shaanxi,centred on the provincial capital,with significant spatial differences.[Conclusions]The coupling and coordination relationship between land use and food production capacity in Shaanxi Province is complex and variable.The results of the study suggest optimizing land structure,strengthening scientific and technological innovation,and implementing differentiated management strategies in order to achieve harmonious growth.
