巡司场位于四川南部宜宾市境内，区域上属于四川盆地南缘山地与云贵高原过渡带，岩溶发育强烈，地下水露头密集分布。通过分析水文地质条件、各水点的水化学组分、氢氧同位素组成等资料，初步确定了研究区地下水径流模式，进而采用水文地球化学模拟方法（Phreeqc反向模拟技术）对结果进行验证分析，最终明确了小鱼洞暗河、凉风洞暗河以及温泉水的径流路径，发现三者相互独立，不存在水力联系，模拟结果与水化学、氢氧同位素分析结果基本一致。研究成果对巡司场地区的地下水开发利用以及工程建设具有重要参考意义。

Xunsichang is located in Yibin City of south Sichuan, where belongs to the transition zone between the southern margin of Sichuan Basin and Yunnan-Guizhou Plateau with strongly developed karst and densely distributed groundwater outcrop. In this paper, the hydrogeological conditions, chemical composition of groundwater, and oxygen and hydrogen isotope data were analyzed to identify the groundwater flow path model in this area, and then the hydrogeochemical modeling method (Phreeqc reverse modeling technique) was used to verify the results. The runoff flow paths of Xiaoyudong ground river, Liangfengdong ground river, and hot spring were determined, which suggested there are no hydraulic connection between them. The simulation results were similar to those obtained from the hydrochemical and isotopic analysis. The results are of important significance for the groundwater exploitation and engineering construction in Xunsichang area.
