Two-dimensional decoupling analysis of water resource behavior carbon dioxide emission and economic growth in China
Using the carbon dioxide emission equivalent analysis(CEEA)method,the carbon dioxide emissionion of 12 water resource behaviors in 31 provinces in China,excluding Hong Kong,Macao,and Taiwan,from 2001 to 2020 were calculated,and dynamic relationship with the level of economic development was explored using a two-dimensional decoupling model.The results show that during the research period,the carbon dioxide emission from water resource behavior in China first increased and then decreased,reaching a peak of 1.04 billion t in 2010,and then decreasing year by year,reaching 850 million t in 2020.Most provinces in China have gradually achieved coordinated development between water resource behavior,carbon dioxide emission,and economic growth.Especially after 2011,most provinces have shown a high economic level-strong decoupling state,but there are still some provinces that have shifted towards a high economic level-weak decoupling state,exposing environmental protection issues.There are significant differences in the two-dimensional decoupling status among provinces at different stages,indicating the importance of formulating differentiated development strategies based on regional conditions.
