【 摘 要 】

The Tapio decoupling model was used to quantitatively evaluate and comprehensively analyse the degree of decoupling, time series evolution and spatial development of economic development and water resources utilization in Guangxi, China from 2006 to 2016. The results show that the impact of Guangxi's economic development on water resources utilization was weakened, which experienced two stages: weak decoupling and strong decoupling. The relations between total water consumption and regional GDP, farmland irrigation water and primary industry GDP were mainly strong decoupling. The relation between industrial water and non-agricultural GDP was mainly weak decoupling. The relationship between water resources utilization and economic growth was relatively good in Yulin, Wuzhou, Baise, Qinzhou and Beihai city, which mainly showed strong decoupling or weak decoupling status, and the economic development still maintain a certain pressure on water resources utilization.
