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.
