Coupling Coordination Evaluation of Urbanization and Food Security in Heilongjiang Province
Taking 12 prefecture-level cities in Heilongjiang Province as the research object, based on the relevant data of urbanization and food security of each city during 2011-2021, an evaluation system of coupling and coordination of urbanization and food security was estab-lished. The entropy method was used to measure the comprehensive index of urbanization and food security. The coupling coordination degree model and relative development degree model are used to quantitatively analyze the coupling coordination stage and relative development type. According to the study:During 2011-2021, the average coupling coordination degree of urbanization and food security of prefecture-level cit-ies in Heilongjiang Province increased from 0.541 to 0.624, the coupling coordination type developed from barely coordination to primary coor-dination, and the coordination level needs to be further improved. In the spatial pattern, the coordinated development level presents the distri-bution characteristics of "high in the west and low in the east". From the perspective of relative development, all prefecture-level cities in Hei-longjiang Province have changed from lagging urbanization and food security to lagging food security and synchronous development. According to different types, corresponding countermeasures are formulated to coordinate the development of urbanization and food security.
