我国三大流域水资源利用效率时空演变特征与影响因素分析
Spatial-temporal evolution characteristics and influencing factors of water resources use efficiency of China's Three Major River Basins
摘要
Abstract
For China to build an ecological society and achieve high-quality development of the basins,scientific and efficient use of water resources is a necessity.To provide strategic support for the effective improvement of water resources use efficiency in the basins,a comparative study on the spatial-temporal evolution characteristics and influencing factors of water resource super-efficiency in the Yangtze River basin,Yellow River basin,and Pearl River basin is conducted.The super-efficiency SBM model of non-expected output was used to measure the water resources use efficiency of each province and region based on the panel data of 21 provinces(municipalities and autonomous regions)in the three basins from 2011 to 2020.Combining the methods of kernel density estimation and the Tobit regression model,a multi-level analysis of water resources use efficiency in the basins was conducted from the perspectives of time series evolution,spatial characteristics and influencing factors of water resources use efficiency.The study demonstrates that during the research period,the Yangtze River basin had the highest water resource use efficiency while the Pearl River basin had the lowest.It also demonstrates that there are some spatial differences in water resource use efficiency as well as the influence of factors like economic development,industrial structure,and import and export demand.Effective suggestions are made based on the research's findings to increase the water resources use efficiency.关键词
