| 摘 要： | 精确量化潜流带水文交换和生物地球化学反应一直是一个挑战，潜流带水文-生物地球化学研究的核心任务是将小尺度上的水文通量及生物地球化学反应动力学与更大尺度上它们对河流水质和生态的累积效应关联起来.基于潜流带水文-生物地球化学耦合原理，系统综述了渗流仪测量、测压管测量、示踪剂注射试验、温度示踪等潜流带水文学研究方法以及野外示踪试验、室内培养试验等生物地球化学研究方法，针对性地评述了潜流带水文-生物地球化学过程在更大尺度上的累积效应及其对河流生态系统的重要意义，并指出未来的研究将从潜流带研究技术方法的先进化、水文地貌理论与模型的深入化和潜流带生物地球化学过程的尺度化等方面持续地发展.

Hydro-Biogeochemistry of Hyporheic Zone: Principles,Methods and Ecological Significance |
| |
| Abstract: | It is always challenging to quantify precisely the hydrologic exchange and biogeochemical reaction in hyporheic zone. The core task for the research of hydro-biogeochemistry in hyporheic zone is to associate the hydrologic flux and biogeochemical reaction dynamics on small scale, with their cumulative effect on water quality and ecology of rivers on larger scale. This paper presents the basic principles of hydrology-biogeochemistry coupling in hyporheic zone, and systematically summarizes hydrologic approaches including measurement by seepage meter, piezometer measuring, tracer injection experiment, streambed temperature profile, environmental tracer and mass balance, and biogeochemical approaches including field tracer experiment and indoor incubation experiment. In addition, this paper specifically illustrates the cumulative effect of hydrologic and biogeochemical processes in hyporheic zone for larger scale, and its ecological significance. It is suggested that the future research on hyporheic zone science shall focus on the advance of research methods, development of hydrogeomorphic theory and model, and up scaling of biogeochemical processes in hyporheic zone. |
