[Spatial Correlation Network Structure of Carbon Emission Equivalent for Water Resources Behavior in China]

Under the national "double carbon" target， it is essential to fully understand the present situation and characteristics of carbon emissions in the water resources field. In order to explore the structural characteristics of the spatial correlation network of carbon emissions from different water resource behaviors in China， research samples were obtained from thirty provinces in China in 2022. According to the four behaviors of water resources development， allocation， utilization， and protection， the carbon emission of each province was calculated， and the space matrix was constructed by using the modified gravity model. Combined with social network analysis， the study analyzed the characteristics of its spatial correlation network. The results showed that： ① Under water resources development， allocation， and utilization behavior， the carbon emissions in southeast China were larger， while under water resources protection behavior， the overall carbon emissions were negative and relatively small in southeast China. ② The carbon emission network of water resources utilization behavior had the highest degree of closeness and stability among the four behaviors. The dependence of each region in the water resources allocation network was the lowest， and the degree of hierarchy and inequality were small. ③ Shanghai， Jiangsu， Beijing， Fujian， and Zhejiang were at the center of the four behavioral networks. ④ The block model division structure of carbon emissions under different water resource behaviors in China was obvious， and there were many correlations among different plates.
