Research on the coordinated development of the ecological environment and social economic system in Hainan Province from the perspective of ecological civilization
The coupling and coordinated development between the eco-environment and social-economic is of great significance for regional sustainable development.Taking Hainan Island as the research area,the evaluation index system of eco-environment and social-economic system was constructed,and the mean square deviation decision method was used to determine the index weight,the coupling coordination model,scissors difference model,and dynamic coupling model were used to analyze the coupling coordination development between eco-environment and social-economic system from 2008 to 2021.The results show that from 2008 to 2021,the eco-environment system index of Hainan Island fluctuated and increased,and the social-economic system index showed an obvious upward trend.From 2008 to 2021,the coupling degree and coupling coordination degree between the eco-environment and social-economic system show a steady growth trend.The coupling coordination degree of the two systems was at a slightly dysfunctional level in 2008 and 2009,it was at the brink of an imbalance level in 2010 and 2011,it was at a barely coordinated level from 2012 to 2020,and it reached the primary coordination level in 2021.The scissors difference between eco-environment and social-economic system increased from 0.771 7 to 4.726 2 degrees from 2008 to 2014,indicating that the gap between the evolution rates of the two systems is increasing,and the gap of between the evolution rates of the two systems showed a fluctuating downward trend,but the change was not large,indicating that the gap of between the evolution rate of the two systems was decreasing from 2015 to 2021.The coupling evolution trend of the ecological environment and socio-economic system showed that the system was in the primary coordinated development stage from 2008 to 2011,and was in the lower coordinated symbiosis stage from 2011 to 2019.It returned to the primary stage of coordinated development in 2020-2021.
