五大连池药泉山地下水循环特征的水化学证据

Hydrogeochemistry Evidence of Groundwater Circulation Features in Yaoquanshan,Wudalianchi

基于药泉山矿水区地下水勘察数据,利用Piper图和统计分析描述了地下水水化学空间分布特征;结合地质与水文地质条件,运用PHREEQC软件对径流路径进行反向模拟,进一步探讨矿水区地下水的循环规律。分析结果表明:矿水区潜水主要接受大气降水及西部地下水补给,承压水无区外补给,地下水主要沿断裂从西南向东径流,自东部南北向断裂带以泉的形式排泄;在西南补给-径流带地下水由潜水下渗补给承压水,在排泄区地下水由深层向上顶托补给浅层地下水。药泉山地下水循环特征可为矿泉水资源合理开发利用提供科学依据。

Based on the test data of groundwater survey, the spatial character of the groundwater chemistry is described by using Pip- er diagram and statistical methods. Based on regional hydrogeological conditions, the PHREEQC software is used for runoff ap- proach reverse simulation to farther explore the cycle method of groundwater. The results show that the phreatic water in mineral water district is recharged by atmospheric precipitation and wedtern groundwater, while the confined water has not outsides supplies. In addition, the groundwater mainly flows from southwest to east along the fault, and discharges in the form of a spring along the eastern north-south fault zone. The Phreatic water recharges confined water by infiltration in the Southwest supplies-runoff area, and the shallow groundwater is recharged by deep groundwater jacking upward in the discharge area. The features of groundwater cycle are the scientific basis for rational development and utilization of mineral water in Yaoquansharn.
