忻州市地下热水年内年际变化特征

Characteristics of Interannual Variation of Groundwater Hot Water in Xinzhou City

忻州市奇村、顿村、逯家庄、卢野、大营、汤头是山西省有名的地热异常区,有着丰富的地下热水资源,为“康养忻州”奠定了得天独厚的自然条件。根据奇村地热站多年的实测资料,综合分析了各个地热区的地下水位埋深、水温及开采量的年内年际变化规律。研究结果表明:忻州市地下热水近10 a来开采量不断增加,致使地下水位埋深增加,水温降低,总体呈动态衰减趋势,急需管理规范。研究结果可为忻州市地下热水的合理开发、科学管理与依法保护提供技术支撑。

Xinzhou Qicun,Duncun,Lujiazhuang,Luye,Daying and Tangtou are famous geothermal abnormal areas in Shanxi Province,with rich underground hot water resources,which has laid a unique natural conditions for“health and nourishing Xinzhou”.According to the measured data of qicun geothermal station for many years,this paper comprehensively analyzes the variation rules of groundwater level buried depth,water temperature and exploitation of each geothermal area in each year.The research results show that the exploitation of underground hot water in Xinzhou has been increasing in the past ten years,resulting in the increase of the buried depth of the groundwater table,the decrease of the water temperature,and the overall dynamic attenuation trend,which is in urgent need of management standards.To provide technical support for the reasonable development,scientific management and legal protection of underground hot water in Xinzhou.
