运用耦合协调模型、地理探测器等分析方法测度了中国中部重点农区—河南省2006—2018年各市域新型城镇化与粮食安全的时空耦合协调水平及具体类型特征,并定量探测了两系统协调发展的影响要素。研究表明:（1） 2006—2018年河南省新型城镇化与粮食安全耦合协调度从0.339稳步上升到0.784,基本实现了"濒临失调→中度协调"的跨越,空间上呈"北部高南部低、中部高东西低"的特征。（2）河南省各市域新型城镇化与粮食安全耦合特征分异明显,长期为粮食安全滞后型市域占比29%,长期为新型城镇化发展滞后型市域占比53%。（3）影响新型城镇化与粮食安全耦合协调度的核心要素转向土地与劳动力资源,外部经济变化...

Based on the theory of human-earth areal system, in-depth discussion of the coordinated development of new urbanization and food security in agricultural areas is the key to promoting high-quality social and economic development in agricultural areas and improving the country's ability to resist food security risks. Taking 17 prefectures in Henan Province as the research unit, the coupling coordination model and geographic detector analysis method were used to measure the level of coupling coordination, and the specific type characteristics bet...
