Abstract
Analyzing regional water resource utilization is of great significance for the conservation and efficient use of water resources.By collecting and organizing data on water resources,water supply,and water usage in Tianjin from 2001 to 2022(a span of 22 years),and introducing methods such as information entropy and equilibrium degree to analyze the water usage structure,the utilization of water resources in Tianjin was evaluated in this study.The results showed that the supply and use of water resources in Tianjin were increasing.Surface water remained the primary source of water supply,while the proportion of groundwater supply was decreasing year by year.The proportion of water supply from other sources increased,such as reclaimed wastewater and desalinated seawater.Agriculture was the main water user in Tianjin.In recent years,the water usage structure was gradually stabilized.By administrative district,the water usage structures in Jinnan District,Beichen District,and Xiqing District were relatively stable,while the equilibrium degree of water usage structure in the six urban districts was relatively low,with Baodi District having the lowest equilibrium degree.关键词
