Yellow River is one of the rivers with scarce water resources.There are a few impor-tant research results about the water supply capacity in2010,but the estimated amount of water supply differs greatly.The highest is69.2billion m3 while the lowest,58billion m3 .Furthermore,the substantial drop of the natural runoff occurred in the1990s.As a result,the runoff amount in a mean hydrological year is11billion m3 less than that of the his toric mean year level.Therefore it is very urgent to make it clear that how much the water supply would be in the2010in the Yellow River since it concerns the sustainable utilization strategy of water resource in the Yellow River drainage basin.The research result of this paper shows that the water supply in2010is only55~56billion m3 in a mean hydrological year,among which surface runoff accounts for39~40billion m3 and groundwater takes another16billion m3 .This result is2~3billion m3 less than the58billion m3 ,which is the least figure of the aforementioned results,and is20%,or14bil-lion m3 less than the largest69.2billion m3 .This poses an even more serious question to the wa-ter demand-supply balance strategy.
