| 中文摘要: |
| 根据2003-2012年用水资料，利用信息熵、方向系数和Mann-Kendall检验对海河流域用水结构特征及其演变趋势进行了研究与分析。结果表明：海河流域用水结构均衡度存在上升趋势，但趋势不显著,用水系统稳定性逐步增强。随着海河流域各类生态补水项目的实施，流域用水结构的改变主要向着生态用水方向发展。 |
| 英文摘要: |
| According to data of water demand from 2003 to 2012,the paper analyzed the water utilization structure characteristics and evolution trend in Haihe river basin by use of information entropy, direction coefficient and Mann-Kendall test. The results showed that balanced degree of structure in the basin has rising trend which is not obvious.The stability of water utilization system gradually strengthens. With the operation of ecological water recharge projects in Haihe river basin,the water utilization structure mainly develop towards the ecological water use. |
