利用主成分分析法构建了融合生产、生活、生态3个维度的综合用水效率测度模型,并利用空间回归方法探讨用水效率的空间关联性.研究表明:我国省际之间的用水效率既存在明显的空间差异,又存在显著的空间关联性;某一省份用水效率受邻近省份的正向影响,周围省份的用水效率均值变动1个百分点会推动该省份的用水效率平均提高1.2个百分点.研究结果为从空间视角提高总体用水效率、减少区域差距提供了参考依据和线索.

An integrated 3-dimensional model to measure the efficiency of water usage is established.The spatial relations of water and its efficiency in use are explored.Studies show that the efficiency of water usage in the provinces of China has not only an obvious spatial difference,but also has a significant spatial correlation.Efficiency of water usage in one province is affected by those of the neighboring provinces.The change of 1% in the efficiency of water usage in surrounding provinces will rise 1.2% in this province on average.The results cna be used as reference for improving overall water e...
