中国中部重点农区新型城镇化与粮食安全耦合协调发展研究——以河南省为例

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，外部经济变化对其协调发展所带来的敏感性逐步降低，科技进步始终是新型城镇化与粮食安全协调发展的促进力。研究旨为中部农区在新型城镇化发展过程中，扛稳国家粮食安全政治责任、担当保障国家粮食安全供给的使命提供参考。

Coupling and Coordinated Development of New Urbanization and Food Security in Main Agricultural Production Regions in Central China:A Case Study of Henan Province

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 between new urbanization and food security in various cities in Henan Province from 2006 to 2018. And quantitatively detected the correlation between the coordinated development of new urbanization and food security. The results showed that: 1) From 2006 to 2018, the coordinated development of new urbanization and food security systems in Henan Province changed from the near disorder type to the moderate coordination type. The degree of coupling coordination showed an upward trend, showing a “North high South low, Central high, East and West low”. 2) The coupling characteristics of new urbanization and food security in Henan Province are distinctly different. Long-term food production lagging cities accounted for 29%, and long-term urbanization development lagging cities accounted for 53%. 3) The core related elements of the coordinated development of new urbanization and food security are gradually concentrated on land and labor resources, and the sensitivity of external economic changed to their coordinated development continues to decrease, and technological progress has always been the driving force for the development of the two systems. The purpose of this study is to provide reference for Henan Province to take the political responsibility for national food security and completing the mission of ensuring national food security supply in the process of new urbanization.
