| description | The total amount of water resources severely affects socioeconomic
development of a region or watershed, which means that accurate
quantification of the total amount of water resources is vital for the area,
especially for the arid and semi-arid regions. Traditional evaluation of
water resources only focused on the qualification of blue water, while the
importance of green water was not fully considered. As the second largest
river in China, the Yellow River plays an important role in socioeconomic
development of the Yellow River basin. Therefore, the blue and green water
resources in the upper Yellow River basin (UYRB) were evaluated by the SWAT
model in this study. The results show that the average annual total amount of
water resources in the UYRB was 140.5 billion m<sup>3</sup>, in which the blue
water resources is 37.8 billion m<sup>3</sup>, and green water resources is
107.7 billion m<sup>3</sup>. The intra-annual variability of the blue water and
green water is relatively similar during the same period. The higher
temperature, the greater difference between the blue and green water. The
inter-annual variability of the blue and green water shows that the trends in
precipitation, blue and green water have a relatively similar characteristic.
The spatial distribution of the blue and green water is characteristic with
gradually decreasing from the northwest to the southeast, and the blue water
around the main stream is greater than that in the other areas. |
