平安县洪水泉乡地下水分布规律及水文特征研究

Study on Groundwater Distribution Law and Hydrological Characteristics of Flood Spring Township in Ping'an County

以青海省平安县洪水泉乡地下水勘查为例,对该区域地下水赋存条件及分布规律、含水岩组划分及富水性、地下水补给、径流与排泄条件、地下水水化学特征进行研究,将区内地下水类型划分为第四系松散岩类孔隙水、碎屑岩类孔隙裂隙水、碳酸岩夹碎屑岩裂隙溶隙水、基岩裂隙水和冻结层水五大类,富水性分级与区域地下水一致。根据区内水文地质条件,离基岩山区近的村庄可以采用引泉方式解决供水,而远离基岩山区的低山丘陵村庄人畜饮水集中供水水源可采用大口井廊道取水工程来解决。通过合理开发利用地下水来解决当地供水需求。

Taking groundwater exploration in Gangquan Township,Ping’an County,Qinghai Province as an example,the conditions and distribution of groundwater in the area,the division of water-bearing rock group and the water-rich,groundwater recharge,runoff and discharge conditions,and groundwater hydrochemical characteristics will be studied. The types of groundwater in the area are divided into Quaternary loose rock pore water,clastic rock pore fissure water,carbonate rock clastic rock fissure gap water,bedrock fissure water and frozen layer water,water-rich grading and region. Groundwater is consistent. According to the hydrogeological conditions in the area,the villages close to the bedrock mountain area can use the way of springs to solve the water supply,while the low-hill hills and villages far away from the bedrock mountain areas can be solved by the water supply project of the large-mouth corridor. Solve local water supply needs through rational development and utilization of groundwater.
