Spatial and temporal patterns of synergistic development of high-quality marine economic development and marine ecological security in three major marine economic circles of China
The"14th Five-Year Plan"emphasizes that the development level of the three major ocean e-conomic spheres should be comprehensively improved to achieve balanced development of the whole o-cean area.Promoting the high-quality development of marine economy and marine ecological security in the three major marine economic circles,and narrowing the gap between the coordinated development of the regions are the key link to promoting the model of marine strongholds to the model of compre-hensive and balanced development of the regions.This paper examines the spatial and temporal evolu-tion characteristics of the spatial correlation patterns and the degree of synergistic promotion of MHQ and MES in China's three major marine economic circles using the coupled coordination degree model and spatial auto correlation analysis.It is found that:(1)The level of coupling and coordination be-tween the two systems has been fluctuating and increasing,and the whole area is in the transition stage from the decline of disorder to the primary coordinated development.(2)There is a significant unbal-anced development trend in the level of synergistic development of the"three circles",and the overall spatial distribution shows a pattern of"East＞North＞South".(3)The spatial correlation of the cou-pling and coordination degree is significant,and the correlation degree increases and then decreases over time;the spatial correlation pattern of the coupling and coordination degree shows certain spatial clus-tering characteristics.
