地下水流系统理论实践与野外教学应用——以三峡专业教学实习为例

Practice and Field Teaching Application of Groundwater Flow System Theory——A Case Study of Professional Teaching Practice in Three Gorges Area

地下水流系统理论是当代水文地质学的核心框架,正在成为当代水文地质学研究的新范式。在地下水相关专业的野外实践教学中,非常有必要将地下水流系统理论的思想和相关调查研究方法融入到野外实践教学中。梳理了当前三峡专业教学实习水文地质教学路线存在的不足,选择三峡地区香溪河流域作为典型教学案例,对地下水流系统理论进行实践,从地下水动力条件、水化学与同位素特征等多信息渠道进行相互验证,构建了多级地下水流系统概念模型,并通过对香溪河流域多级地下水流系统案例进行教学应用,从野外现象类、工作方法类和专题调查类三个方面对野外教学知识点进行了设计,以期促进地下水流系统理论的教学,丰富并拓展三峡专业教学实习的教学资源。

Groundwater flow system theory is the core framework of contemporary hydrogeology,which is becoming a new paradigm of contemporary hydrogeological research.In the field practice teaching of the majors related to groundwater,it is very necessary to integrate the ideas of groundwater flow system theory and related investigation and research methods into field practice teaching.This paper sorts out the shortcomings of current hydrogeological teaching routes in professional teaching practice in Three Gorges Area.We choose Xiangxi River basin as a typical case to practice groundwater flow system theory.A conceptual model of hierarchical groundwater flow systems is constructed from multiple information channels such as groundwater hydrodynamic conditions,hydrochemical and isotopic characteristics.We take the case of hierarchical groundwater flow system in Xiangxi River basin into teaching application,and design the knowledge points of field teaching from the three aspects of field phenomena,work methods and special investigation,which will promote the teaching of groundwater flow system theory and enrich the teaching resources in professional teaching practice in Three Gorges Area.
