【摘要】：水资源匮乏的问题始终阻碍着我国社会经济的发展。全国范围内半数以上的城市缺水情况十分明显,天津也属于缺水城市之一。对于防汛工作来说,目前已经有很明确的汛限水位可供参考,便于防汛部门对可预见的洪水做出快速反应,但是对于抗旱工作来说,并没有类似明确的旱限水位作为旱情指标可供参考。对于这方面的研究继续深入。本文的主要研究内容和成果如下:1、对于桥水库所处区域的水资源概况进行了深入研究,着重介绍于桥水库对天津市的防洪、供水起到的重要作用。重点分析天津市三十年来的水资源数据,在用水保障率、水位高程等限制条件下,运用最低生态水位法,通过单、双月滑动平均计算获得于桥水库旱限水位。2、对历史水位资料进行统计,分析得到了于桥水库多年最低水位与旱限水位之间的对比关系,完成对旱限水位结果的合理性校验。对于桥水库供水水质存在的问题及原因进行了具体分析说明,结合实际调水原则对旱限水位成果进行了验证。3、设计并建设了针对于桥水库旱限水位的水情预警系统,对系统功能、架构、数据库等内容进行了详细的说明。对于桥水库旱限水位在水情预警系统中的实际应用和影响进行了分析。研究得出旱限水位在预警系统中的应用对于桥水库区域旱情预警起到了一定的作用。
[Abstract]:The shortage of water resources has always hindered the social and economic development of our country. More than half of the cities throughout the country water shortage is very obvious, Tianjin is also one of the water shortage cities. For flood control work. At present, there is a clear flood limit water level for reference, for flood prevention departments to make a rapid response to predictable floods, but for drought relief work. There is no similar dry limit water level as a drought index for reference. For the further study of this area. The main research content and results are as follows: 1. This paper makes a deep study on the water resources in the area where the Yuqiao Reservoir is located, emphatically introduces the important role of the Yuqiao Reservoir in flood control and water supply in Tianjin, and analyzes the water resources data of Tianjin in the past 30 years. Under the limited conditions of water security rate and water level elevation, the minimum ecological water level method is used to calculate the dry limit water level of Yuqiao Reservoir by single and bimonthly sliding average calculation. The historical water level data are statistically analyzed. The correlation between the minimum water level and the drought limit water level in Yuqiao Reservoir is obtained. The rationality of the results of drought limit water level is verified. The problems and causes of water supply quality in Yuqiao Reservoir are analyzed and explained. Combined with the principle of actual water transfer, the results of limited water level are verified. 3. This paper designs and builds a water regime early warning system for the limited water level of Yuqiao Reservoir, which has the function and structure of the system. The actual application and influence of the limited water level of Yuqiao Reservoir in the water regime early warning system are analyzed. The application of the limited water level in the early warning system to the Yuqiao Reservoir area is obtained by studying the application of the drought limit water level in the early warning system. Drought warning plays a role.
