| 摘 要： | 针对“生态用水”概念及使用混乱的现象，本研究对生态系统的需水、用水的概念进行描述和界定，并对背景和研究状况进行了综述，提出了不同生态系统的用水估算方法。在此基础上，提出了目前生态用水的相关研究中存在的问题，以及在生态用水的机理上研究方面的可能突破。最后讨论了在全球气候变暖、水资源亏缺的背景下，生态用水的时间变化及与之相应的水资源供需平衡问题将会成为关注的热点问题。

| Abstract: | The issues about ecological water use are summarized from its concept,background,estimation method and research advances.On the basis of the summary,some questions in research at present and the possible breakthrough in mechanism investigation of ecological water use are put forward.At last,it is pointed out that under the background of climate warming and shortage of water resource,the spatial and temporal variation of ecological water use corresponding to supply and demand balance of water resource will become hot scientific issue. |
