The coupling and coordination characteristics of agricultural green water resources and agricultural economic development in China

Water resources are the source of life for people to survive, especially in agriculture. Water resources provide necessary support for agricultural economic development and irrigation management. Using the panel data from 2013 to 2019, this paper uses the coupled coordination model to explore the degree of synergy between agricultural water resources efficiency (AWRE) and agricultural economic development level (AEDL), and analyzes the spatial correlation of coupling coordination degree (CCD) between the AWRE and AEDL, and further predicts the relationship between the two. The results are as follows: (1) There are superb variations in the CCD among provinces, and the diploma of coordination is greater in the south than in the north; (2) In the spatial correlation pattern, high-high agglomeration areas exhibit an growing trend, and the variety of low-low agglomeration areas is small; and (3) Through the prediction, it is found that in the further, the CCD will show a trend of slow increase in future. For purpose of the coordinated perfection of the two systems, we need to completely discover the connotation of coordinated improvement and promote regional cooperation.
