有闸控制湖泊分期分级旱限水位研究

Study on the stage and grade drought limited water level of lake controlled by sluice

干旱灾害是主要的自然灾害之一,严重影响了居民生活、工农业生产和生态环境用水安全。旱限水位是做好水源工程抗旱调度决策的重要依据。本文综合考虑湖泊上游来水、区间用水、通航等因素,提出了有闸控制湖泊分期旱限水位和旱枯水位的划分方法,并以女山湖为典型区域开展应用研究。结果表明:旱限水位和旱枯水位的划分基本符合女山湖的实际情况,能够为区域防旱抗旱提供一定的技术支撑。

Drought disaster is one of the main disasters affecting the water supply safety of water source projects.And it seriously affects the water safety of the residents,industrial and agricultural production and ecological environment.The drought limited water level is an important basis for drought prevention and drought relief of water source projects.In this paper,the division method of stage drought limited water level and drought dry water level is proposed based on the upstream water,interval water,navigation and other factors.And take Nvshan Lake as a typical area to carry out application research.And the results show that drought limited water level and drought dry water level is basically in line with the actual situation of Nvshan Lake and it can provide certain technical support for regional drought prevention and drought relief.
