Characteristics of groundwater function distribution and its indication for sustainable groundwater resource development in interior basins,northwestern China
Based on assessment of groundwater function,the distribution and combined characteristics of groundwater functions(namely groundwater resource function,groundwater ecological function,and groundwater geologic environment function) were summarized,and then a conceptual mode of groundwater function distribution in interior basins,northwestern China was brought forward.From piedmont plain to floodplain,it can be divided into three subareas: the proluvial fan subarea in piedmont plain,the oasis subarea in floodplain and the desert subarea in lower reaches.Finally,some suggestions were provided for sustainable groundwater resource development in different area.
