泉林泉群泉流量演化与泉水景观流量研究

Study of Quanlin Spring Groups Flow Evolution and Spring Landscape Flow

摘要: 本文通过对泉林泉域的水文地质特点的调查，收集了泉林泉群30多年的泉流量资料，分析了泉水的成因；根据泉流量的历史演变过程，划分了泉水喷涌的历史阶段，并分析了不同阶段影响泉水流量衰减的主要因素，降雨是泉水衰减的自然因素，现状条件下深层地下水的开采是泉流量衰减的主要人为因素；在对地下水位和泉流量历年数据相关性分析的基础上，建立了地下水位与泉流量的数学模型，以泉群的出露标高为底限水位，计算出了不同预警条件下泉水喷涌的景观流量，保证四大主泉眼喷涌的地下水位为133.45 m，此时泉林泉群的景观流量为8.12万m3/d，保证泉林泉群全部泉群喷涌的地下水位是134.13 m，此时泉林泉群的景观流量为10.89万m3/d。该成果对于保障泉林泉水持续喷涌、泉群生态环境健康、泗河源头水源地供水安全具有重要的意义，为泉域地下水及泉水的管理、保护、预警等提供基础数据支持。

Abstract: This article investigated the hydrogeology of Quanlin by collecting data of Quanlin springs more than 30 years and analyzing the origin of springs. According to the historical evolution process of springs flow, we divide the different stages of springs flow and analyze the main factors influencing the springs discharge. Rainfall is the mainly natural factors and the mining of deep groundwater is the main human factors. By analyzing the correlation between historical water level and spring flow, a mathematical model is established to calculate the spring landscape flow in different warning conditions by the elevation as the lowest water level that is 133.45 m for protecting the main four springs, while the landscape flow is 81,200 m3/d. If the landscape flow is 108,900 m3/d when the water level is 134.13 m, then all the springs are flowing in Quanlin. The work is very important to protect the springs flowing, the ecological environment health and the safety of water supply in Sihe river basin, which provides the basic date support for the management, protection and warning of springs.
