| 摘 要： | 水库作为重要的蓄水和供水工程，对城乡供水安全起着极其关键的作用。干旱时期，水库可能由于前期蓄水不足满足不了后期的用水需求，这就需要及早作出预警，以便采取应对措施。本文以永康市的杨溪水库为研究对象，界定了黄色、橙色、红色供水预警等级，采用长系列（1965-2009）逆时序逐日调节计算得出历年逐日水库所需蓄水量成果，并对45年成果进行统计分析，确定了杨溪水库黄色、橙色、红色三条预警线及各预警线的浮动上限。本研究成果能够指导干旱期水库供水运行管理工作，使区域的经济社会不因缺水产生过度影响，确保区域平稳有序度过不同程度的干旱期。

| Abstract: | AS an important water supply project, the reservoir plays a key role to the urban and rural water supply security. Because of the deficiency of the early reservoir inflow, the reservoir can’t meet the water needs of the next stage in during drought period. The early warning to reservoir storage is needed, in order to take measures more early for the water shortage. This paper takes Yangxi Reservoir in Yongkang city as research object, defines three-grade early warning described by the colors yellow, orange, red, and blue respectively, gives the results of the one-day reservoir storage capacity inverse timing adjustable calculated with one day for a period of time by using series of multi years data ( 1965-2008 ). Through the statistical analysis of the results of reservoir storage capacity, this paper identified the yellow, orange and red lines and Change limits of three-grade warning lines. The results of this study can guide the drought period water supply of reservoir operation management, so that regional economy society does not unduly influence due to the lack of water, to ensure to get through different degrees of drought period smoothly. |
