LANDFORMS EFFECT THE DISTRIBUTION AND CIRCULAR MODEON GROUNDWATERIN SHIYANG RIVER BASIN

摘要

The paper discussed the relation between landform and groundwater. With the result that, the distribution ofrnhydrogeology units and morphologic units are the same, because different morphologic units supply different distribution status andrncircular mode for groundwater. Mountainous and hills area are the replenishment headwater because their hole and cranny are spacernthat groundwater exist. Alluvial fans are the location that groundwater reserves and circulates. Groundwater has different existencernstatus in subsurface of plain because of different lithology, thickness, density and porosity in sediments. Frozen crust water mostlyrnexists exceeding cold mountain area.
