    Abstract:

    Based on the economic and social indicators and water resources data of Guangdong, Hong Kong and Macao Greater Bay Area from 2009 to 2019, the spatial equilibrium of population, GDP and water resources was studied through Theil index and Gini coefficient, and the water resources load index model was constructed to analyze the degree of regional water resources development. The results showed that the matching degree between population and water resources, GDP and water resources in Guangdong, Hong Kong and Macao Greater Bay Area was low in 2019, and the Gini coefficient was 0.520 and 0.651,respectively, which belonged to a highly uneven level, and the Gini coefficient showed an upward trend. The same conclusion was obtained through the Theil index. Inter-regional differences contribute greatly to the overall difference, while the matching gap between population, GDP and water resources in the region was not prominent. In 2019, the water resources load index of Guangdong, Hong Kong and Macao Greater Bay Area was 4.0, the grade was grade III, and the degree of development and utilization was at the medium level. The water resources load gap among cities was wide, and showed an increasing trend year by year. Areas with large economic aggregate, dense population and relatively insufficient water resources had high degree of development and utilization and low potential. The spatial distribution of water resources in Guangdong, Hong Kong and Macao Greater Bay Area is not coordinated with the layout of productivity, and the spatial imbalance of water resources has a trend of further aggravation.
