山东省黄河流域用水结构演变特征及空间分布规律.

In order to coordinate the relationship between water resources and economic and social development in the Yellow River Basin, based on the current water consumption data of the Yellow River Basin in Shandong Province from 2008 to 2022, the evolution characteristics and spatial distribution law of water consumption structure in the Yellow River Basin in Shandong Province were analyzed by using the methods of information entropy and equilibrium degree, Lorenz curve and Gini coefficient. The results show that the agricultural water use in the Yellow River Basin in Shandong Province no longer has a single absolute advantage, and the water resources allocation is transforming into multi-objective. The information entropy and equilibrium degree show a synchronous upward trend, indicating that the distribution of various types of water consumption is developing towards uniformity. From 2008 to 2022, the spatial equilibrium degree of agricultural water use in the Yellow River Basin of Shandong Provinceis is decreased obviously, the spatial equilibrium degree of industrial water use is increased slightly, the spatial equilibrium state of domestic water use does not change greatly, and the spatial equilibrium degree of ecological water use is increased obviously. From 2008 to 2022, the spatial distribution of agricultural water use in the Yellow River Basin in Shandong Province changs from an obvious equilibrium state to a relatively balanced state, while the spatial distribution of industrial and domestic water use has always been relatively balanced, and the spatial distribution of ecological water use has changed from a poor equilibrium state to a relatively balanced state. The proportion of agricultural water in Dezhou is the highest, the proportion of industrial water in Zibo is obviously higher than that in other regions, and the proportion of domestic water in Jinan is the highest and slowly rising. In 2018, the proportion of ecological water in Jinan is the highest, and the proportion of ecological water is the lowest in Dezhou. [ABSTRACT FROM AUTHOR]
