Evaluation and forecast of the coupled coordinated development of economy-environment-mineral resources in Henan Province
The analysis from 2010 to 2022 in Henan Province employed a combination of the com-posite weighting method,the coupling coordination degree model,and the obstacle degree model to examine the coupling and coordination effects,as well as the obstacle factors of the economy-envi-ronment-mineral resource nexus.Furthermore,the ARIMA-GM model was employed to predict the developmental trend of coupled coordination in Henan Province for the years 2023 to 2027.The re-sults indicate that the economic development index has shown a steady upward trend,while the en-vironmental and mineral resource development indices have exhibited a"W"shaped trend.Al-though the overall system's coupled coordination level has improved,it still remains in a state of imbalance.The descending order of the obstacle degrees to coordinated development among the sub-systems is as follows:the economic sub-system,the environmental sub-system,and the mineral resource sub-system.Predictions under different scenarios reveal that scenario 4 demonstrates the greatest relative improvement,with a coupled coordination degree of 0.815 by 2027,reaching the category of good coordinated development.
