Comprehensive analysis of water consumption structure in China and study on its driving forces
Based on the water footprint method,the water consumption of agriculture,industry,domestic,and ecology sectors in 31 provinces(autonomous regions,municipalities directly under the central government)in China,excluding Hong Kong,Macao,and Taiwan,in 2010 and 2019 was quantified.The Gini coefficient,inequality index,and water resources carrying capacity were used as the main indicators to evaluate the spatial uniformity,local adaptability,and water resources vulnerability of the water consumption structure in each province.The grey correlation method was used to analyze the driving forces of water consumption characteristics in each department.The results show that there is a significant difference in the uniformity of water consumption spatial distribution among various departments,with the agricultural department being the best,with a slight decrease in 2019 compared to 2010.The water resource adaptability of the domestic and industrial sectors is the best,with little change in 2019 compared to 2010.The water resources carrying capacity in northern regions is more fragile than in southern regions,and overloaded areas are mainly concentrated in areas such as the Huang-Huai-Hai region.The situation in 2019 was more severe than in 2010.The planting area of crops,industrial revenue,urban domestic sewage discharge,and investment in urban environmental infrastructure are the main driving factors for the water consumption structure of agriculture,industry,domestic,and ecology sectors,respectively.
