The spatial-temporal distribution pattern of water resources utilization in China
The rational use of water resources is of vital importance to the regional economic and social development and the sustainable development of man and nature.Based on the panel data of 31 provincial administrative units in China from 2004 to 2015,the moving track of water resource gravity center in China was measured by using the gravity analysis model,and the structural changes of water resources utilization types were also analyzed.On this basis,exploring the character of temporal and spatial changes of water use efficiency in China's provinces.The results show that there is great instability in the trajectories of the center of gravity of the total water resources in China,while the center of gravity of the water resource movement is roughly "Z" type change.The spatial variation of ecological water and industrial water is the largest,while that of domestic water and agricultural use is small,and the variation of water consumption and agricultural water use are basically the same.China's water use efficiency is basically showing the ladder-like pattern of high in the east and low in the west.
