Study on the Relationship between Water Resources Utilization and Economic Growth in Tarim River basin from the Perspective of Water Footprint

Taking the Tarim River basin as the research object, the water footprint was calculated based on the water footprint theory based on the relevant data from 2008 to 2019, and the water resource evaluation system was constructed to analyze the water footprint and water resource utilization of the Tarim River basin from three levels of structure, benefit, and ecology. Based on the water footprint theory, the annual water footprint and GDP of Tarim River basin were used to construct the Tapio decoupling model, and the decoupling type between water resources utilization and economic growth was obtained. The relationship between water resource utilization and economic growth in Tarim River was analyzed by combining the decoupling type evaluation and water footprint evaluation. The internal benefit is poor, and the external benefit is good; The degree of water resource shortage is on the rise, and the self-sufficiency rate of water resources is large. On the whole, the decoupling strength increases gradually. Decoupling strength has obvious industrial influence characteristics. Based on the above research conclusions, the sustainable economic and ecological development of the Tarim River basin can be realized from two aspects: reducing water footprint and strengthening decoupling intensity.
