摘　　要：为厘清丘陵山地区耕地利用隐性形态变化的规律,以重庆市为研究区,采用综合指数模型、耦合协调度模型和地理探测器等方法,探讨重庆市耕地利用隐性形态时空演化特征、内部系统的耦合协调性特征及驱动力。结果表明:①2010-2022年,重庆市耕地利用投入—组织适应性—产出三维隐性形态不断优化,其中投入形态和产出形态缓慢分化,组织适应性形态无明显分化。②2010-2022年,重庆市耕地利用隐性形态中投入—组织适应性—产出耦合协调水平呈现逐步提升趋势,中级协调区域始终为主体,高级协调区域数量在研究期后期显著增加;耦合协调水平区域分布呈现组团式极化特征,主城都市区和渝东北地区协调水平较高。③重庆市耕地利用隐性形态的耦合协调受经济、社会和自然因素的综合影响。主要驱动因素包括能源投入、从业者生计价值、耕地地势平坦度和耕地肥力。机械动力投入、耕地整合度和耕地区位邻近性则表现出阶段性影响。随着技术发展和城镇化的推进,劳动力、化肥等因素的作用逐渐减弱。耕地利用应充分遵循投入、组织适应性和产出三维隐性形态协调发展规律,因地制宜优化耕地资源配置并进行适当的政策干预,促进耕地资源可持续利用。To clarify the law of recessive morphological changes in cultivated land use in hilly and mountainous areas,this paper takes Chongqing as the research area and uses comprehensive index model,coupling coordination model and geographic detector to explore the spatiotemporal evolution characteristics,the coupling and coordination characteristics and the internal system s driving forces of recessive morphological changes in cultivated land use of Chongqing.The results show that:①From 2010 to 2022,the“three-dimensional”recessive morphology of input-output-organizational adaptability of cultivated land use in Chongqing was continuously optimized,in which the input morphology and output morphology were slowly differentiated,and the organizational adaptability morphology had no obvious differentiation.②From 2010 to 2022,the coupling coordination level of input-output-organizational adaptability in the recessive morphology of cultivated land use in Chongqing showed a gradual upward trend,with intermediate coordination areas as the main body,and the number of advanced coordination areas increased significantly in the later period.The regional distribution of coupling coordination level presented a cluster-type polarization feature,and the coordination level in the main urban area and northeastern Chongqing was relatively high.③The coupling coordination of the recessive morphology of cultivated land use in Chongqing was affected by a combination of economic,social and natural factors.The main drivers included energy input,livelihood value of practitioners,farmland flatness and soil fertility.Agricultural machinery power input,farmland integration and location proximity of farmland showed phased impacts.With the advancement of technology and urbanization,the role of factors such as labor and fertilizers has gradually weakened.The utilization of cultivated land should fully follow the“three-dimensional”recessive morphology coordinated development law of input,organizational adaptability and output,and optimize t
