主　　题：mine drainage river water heavy metal geographic information system(GIS) Kosaka watershed 

摘      要：Focusing on the origin of the heavy metal,this study aims to build an imputed method to estimate the heavy metal content in river water by making a distinction between the heavy metal of natural origins and that caused by human *** by GIS,Kosaka watershed within the Hokuroku basin was divided into several sub-watershed polygons and the outflows of water and Cu were calculated for each *** with the natural origin,the dominant Cu emissions affected the river water more significantly in *** on the mass balance closure,the heavy metal content of Cu in the Kosaka River was estimated by the conflux accumulation of tributaries and mine *** estimated Cu concentrations were checked by comparing with the actually measured values at monitoring points along the Kosaka River and the results are coincidence with each other in *** is revealed that the mainstream water quality could be estimated by seizing the water quality of upstream tributaries and human drainages.
