Water use characteristics and impact factors in the Yellow River basin, China

ABSTRACT This study focuses on the water use characteristics and impact factors in the Yellow River basin. Water use increased from 1980 to 2000 and then stabilized. Water use in the eight regions of the basin varies significantly in both time and space. Water use in different sectors is sensitive to variations in the irrigation area, industrial added value, efficiency, population and urbanization. Change trends are the results of the joint effects of supply-and-demand relationship and water policy. Water use is insensitive to precipitation, because irrigation mainly relies on river water and groundwater.
