中文摘要：
为协调水资源与社会经济发展的关系，引入信息熵理论分析了东江流域2000-2011年用水现状、用水结构及其演变特征与发展趋势。结果表明，东江流域各地区信息熵均不断增加，用水结构系统趋于稳定，但各市县信息熵增加速度各有不同。从东江流域上游至下游，区域用水结构可分为初、中、高级，用水结构具有分阶段演变的特点。社会经济因子是东江流域用水结构变化主要驱动因子。
英文摘要：
In order to coordinate the relationship between water the current water situation, water structure and its evolution 2000 to 2011 were analyzed by information entropy theory in resources and social economic development, characteristics and development trend from Dongjiang river basin. The results showed that the information entropy values increased, water structure system tended to be more stable, but the growth rate of the information entropy was different in various cities and counties in Dongjiang river basin. The water structure could be roughly divided into elementary, intermediate and advanced levels from up- stream to downstream in the Dongjiang river basin, the water structure had periodic characteristic for a long time evolution, and social-economic factor was the major driving factor of water structure in Dongjiang river basin.
