- Abstract:
-
We describe the equilibrium degree of water resources allocation and the dynamic evolution of equilibrium by Gini index and its decomposition and migration of barycenter based on ecological footprint of water resources pattern model. The results show that: (1) the ecological pressure of water resources is higher in the north and lower in the south, and the regions with high economic efficiency of water resources mainly concentrate in the Yangtze River Economic Belt, the Bohai Rim Economic Zone, the southeast coastal area and the surrounding region of Beijing—Tianjin—Hebei; (2) the overall Gini index of water resources ecological pressure is approaching the equilibrium warning line of 0.4 for a long time, and the ecological pressures of water resources in different regions are quite different, the overall Gini index of water resources economic efficiency is low, and the ecological footprint of water resources in China does not match the carrying capacity and is more in line with GDP; (3) during the period from 2006 to 2015, the barycenter of the ecological pressure of water resources is located in the northeast of Chinese geographical barycenter, and has a trend of eastward migration; the barycenter of the economic efficiency of water resources is located in the southeast of Chinese geographical barycenter, and has a trend of migration towards the southwest.
