| 摘 要： | 潜流带是河流生态系统中活跃的生态群落交错区，是地表水和地下水相互作用的重要界面。研究潜流带内存在的潜流交换机制对评估水资源的开发利用以及维持和修复河流生态系统健康有着重要意义。系统介绍了温度示踪方法的一维垂向稳态和瞬态热运移解析模型，梳理归纳了基于温度示踪的时序数据采集方法、信号分析方法和数值方法的相关研究进展，最后对比论述了温度示踪方法的优势和存在的主要问题，同时指出了地下水的多维流动、温度测量的不确定性以及非理想条件对解析模型的影响仍是未来温度示踪方法需要进一步研究的重点。

| Abstract: | The hyporheic zone, which is an important interface between the surface of the water and groundwater, is an active ecotone in a river ecosystem. The study on hyporheic zones and hyporheic exchange mechanism impose significant effects in assessing the development and utilization of water resources, and in maintaining and restoring the health of a river ecosystem. The present study systematically introduces the analytical model of a one-dimensional vertical steady-state and transient heat transport equation in the temperature tracer method, and combines and summarizes the research progress of temperature time-series data collection methods, signal analysis methods, and numerical methods, based on temperature tracing. Finally, the advantages and main problems of the temperature tracer method were compared and discussed, indicating that the uncertainty in temperature measurements, multi-dimensional groundwater flow, and impact of non-ideal conditions on these analytical models should still be emphasized in future studies on temperature tracer methods. |
