【 摘 要 】

This paper selected 11 provinces and cities in the Yangtze economic belt as research areas, and interregional differences & spatial correlations of their overall, industrial and agricultural water intensity were measured. The results show that the intensity of water resource consumption decreases significantly in all provinces and cities, but the intensity of water resource consumption decreases slightly. The variation coefficient of the total water resource consumption intensity of provinces and cities is relatively stable, while the inter-regional difference of agricultural water resource consumption intensity is increasing, and the industrial sector shows a trend of first increase and then decrease. The spatial correlation between total and agricultural water resource consumption intensity was significant but decreased year by year, while there was no significant spatial correlation between industrial water resource consumption intensity. The study suggests that the strictest water resource management system should be further implemented to strictly control the total amount and intensity of water resource consumption in the Yangtze river economic belt. China should promote industrial transformation and upgrading, encourage the development of advanced industries such as new and high technology industries, and establish a synergy mechanism and a reasonable compensation mechanism for the use of water resources in the Yangtze River economic belt.
