Prediction of Water Demand for the Development of Energy Resources-Oriented Cities Along the Ji-Shaped Bend Region of Yellow River
摘要
Abstract
In order to analyze the changes of water demand of energy resources-based cities in the"Ji-shaped bend"of the Yellow River,based on the water Economy Kuznets Curve-WEKC,the relationship between per capita water consumption and per capita GDP in 14 re-sources-based cities along the Yellow River during 2000-2022 was analyzed.The variation characteristics of regional water use were further extracted by variational mode(VMD)decomposition,and the future water demand was predicted by support vector regression(SVR).The results show that the WEKC curve of the"Ji-shaped bend"of the Yellow River energy resources-based cities in the study period presents a variety of connection patterns consisting of U-shaped and inverted U-shaped,and will continue to show an interweaving pattern of water de-mand growth and decline.The WEKC curve is characterized by fluctuation and shows periodicity and regularity with economic development,which is helpful for in-depth exploration of the evolution law of water demand in the course of regional development.Based on the research conclusions,relevant suggestions are put forward for the future research direction of WEKC curve.关键词
