安化向斜由于褶皱及断层构造作用,地下水径流和出露特征具有一定规律,且出露泉点多作为附近村庄的生活水源。通过对研究区内水文地质条件、地下水水化学组分、氢氧同位素组成等进行分析,采用水均衡法、水文地球化学反向模拟技术等手段,最终确定研究区内共存在3种不同的地下水径流模式:沿可溶岩条带地下水径流模式、断层导通的地下水绕轴径流模式及沿断层破碎带的地下水径流模式,研究成果探明了该地区地下水的径流和排泄规律,对该地区地下水资源的开发利用和保护具有重要的参考意义。

[Abstract]
Due to fold and fault structures of Anhua syncline, groundwater runoff and outcrop characteristics have certain rules, and most of the dew point springs are used as living water in nearby villages. In this paper, hydrogeological conditions , chemical composition of groundwater, and hydrogen and oxygen isotopic data in the study area were analyzed, and the water balance method, hydrogeochemical reverse simulation and other means were adopted. It was found that there were three kinds of groundwater runoff modes co-existing in this area: groundwater runoff patterns along the strip of karst, fault conducting groundwater runoff patterns around the syncline axis and groundwater runoff patterns along the fault fracture zone. The results revealed the rules of runoff and discharge of groundwater in the area, therefore providing significant reference for the development, utilization and protection of groundwater resources there.
