摘　　要：以我国31个省(市、区)为研究对象,构建了省域层面城镇化与粮食生产耦合协调度的评价指标体系,并采用熵值法、综合指数模型、耦合协调度模型以及相对发展指数模型对2004─2021年我国省域层面城镇化与粮食生产的耦合协调度及其时空特征进行了分析。结果显示:2004─2021年我国省域层面的城镇化水平、粮食生产水平,以及2个系统间的耦合协调度和相对发展指数总体上均呈现波动上升的趋势;在2021年,我国省域层面的城镇化水平总体呈现东部高、中部次之、西部最低的空间分布,粮食生产能力整体上呈现西部最低、东部次之、中部最高的空间分布,城镇化与粮食生产的耦合协调度总体上呈现东部高西部低、南北低中部高的空间分布格局,但地区间的差异在不断缩小。The national 31 provinces from 2004 to 2021 were taken as the research objects,and the evaluation index system of provincial urbanization and food production coordination degree was constructed.The entropy method,composite index model,coupling coordination degree model and relative development index model were used to analyze coupling coordination degree and the spatial-temporal characteristics of China’s provincial urbanization and food production.The results show that the urbanization level,grain production level,coupling coordination degree and relative development index of the two systems show a fluctuating upward trend from 2004 to 2021.In 2021,China’s urbanization level at the provincial level generally presents a spatial distribution of high in the east,second in the middle and lowest in the west,and grain production capacity as a whole presents the lowest in the west,second in the east and highest in the middle.The coupling coordination degree between urbanization and grain production generally presents a spatial distribution pattern of high in the east and low in the west,low in the north and south and high in the middle,while regional differences are narrowing.
