Carbon dioxide emission equivalent and spatial disequilibrium of water resource behaviors in China
The carbon dioxide emission equivalent analysis(CEEA)method was used to calculate the carbon dioxide emission equivalent(CEE)of water resource behaviors in China's 31 provincial administrative regions excluding Hong Kong,Macao,and Taiwan,involving 16 kinds of water resource behaviors in four dimensions,including water resource development,allocation,utilization,and protection.The spatial disequilibrium of CEE of water resource behaviors in China and its sources were explored using the Dagum Gini coefficient.The results show that the total CEE of water resource behaviors in China was 138.1984 million t in2020,and the total CEEs of water resource behaviors in the four dimensions of development,allocation,utilization,and protection were 212.9768 million,43.7145 million,-31.4171 million,and-87.075 8 million t,respectively.CEE of water resource behaviors generally showed a decreasing spatial distribution pattern from east to west,and Jiangsu and Guangdong had the highest CEE of water resource behaviors.CEE of most water resource behaviors showed strong spatial disequilibrium,and the Dagum Gini coefficient of CEE for hydropower behavior was 0.73,showing the strongest spatial disequilibrium of CEE.The inter-regional net value difference was the main contributing factor to the spatial disequilibrium of CEE of water resource behaviors.
