Research on Coupling Coordination of Food-Arable Land Ecological Security Based on BP Neural Network
By selecting the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2011 to 2020,the index evaluation system was constructed,the BP neural network was used to evaluate food security and cultivate land ecological security,the coupling coordination model was established for a-nalysis,and finally the BP neural network was used to make predictions.The analysis results show that during the study period,food security and cultivated land ecological security in the Yangtze River Econom-ic Belt have been improved to varying degrees,and the level of coupled and coordinated development of food cultivated land ecological security has also developed from a mild imbalance level in 2011 to an inter-mediate coordination level in 2020,and it is predicted that it can reach a good coordination level in 2025,but there are regional differences in the degree of coupling coordination.Therefore,the provinces of the Yangtze River Economic Belt should work together to formulate reasonable strategies according to the re-source advantages and actual conditions of each region to promote the coordinated development of food ara-ble land ecological security.
