Research on the Coupling Relationship between Marine Resources and Environmental Carrying Capacity and Marine Economy in Jiangsu Province

Abstract

This paper takes the coastal area of Jiangsu Province as the research area, collects the relevant statistical data of the coastal area from 2010 to 2020, and uses the coupling degree and coupling coordination degree model to analyze the degree of marine economy-marine environment coupling in Jiangsu Province in the past 10 years and its correlation. The coordination type is analyzed and evaluated. The research results show that the coupling index of marine resources and environmental carrying capacity and marine economy in Jiangsu Province fluctuates up and down in the interval of 2010-2020. trend. From 2010 to 2020, the coupling index of marine resources and environmental carrying capacity and economic development level in the coastal areas of Jiangsu Province showed an inverted "U"-shaped change, which is in line with the environmental Kuznets curve. The coupling coordination index fluctuates repeatedly, and the value is between 0.4 and 0.8. The coupling stage is from the antagonistic stage to the running-in stage. The coupling coordination type is mainly based on the coordinated development type, and the coupling level roughly develops from a mild imbalance to a low-level coordinated development to a well-coordinated development. It began to rise rapidly, and the coupling status is good. The coupling status of Lianyungang and Yancheng needs to be further improved.
