玉符河强渗漏带保泉补源作用分析

Analysis of the role of strong leakage zone in Yufu River in spring protection and source supplement

本文通过分析2022年6-8月卧虎山水库向玉符河的泄流量对趵突泉地下水位的影响,探究玉符河强渗漏带在保泉工作中的作用,以期提高玉符河强渗漏带补源效益。数据分析表明,卧虎山水库向玉符河泄流量与趵突泉地下水位成正相关,通过玉符河强渗漏带地表水向地下水的转换进行保泉补源效果明显,其对趵突泉地下水位的影响存在一定时滞性。

This paper analyzes the impact of discharge from Wohushan Reservoir to Yufu River during June to August 2022 on the groundwater level of Spouting Spring,aiming to explore the role of the strong leakage zone in Yufu River in spring protection and source supplement,with the aim of enhancing the benefits of source replenishment in the strong leakage zone of Yufu River.Data analysis reveals a positive correlation between the discharge from Wohushan Reservoir to Yufu River and the groundwater level of Spouting Spring.The evident effect of maintaining spring water source replenishment is achieved through the conversion of surface water in the strong leakage zone of Yufu River to groundwater,with a certain time lag effect on the groundwater level of Spouting Spring.
