| Abstract: |
| The system of underground water resources assessment is established by computer technology and balance method and is applied in the blown-sand region of Northern Shaanxi Province. The system has many functions such as data adding, deleting and maintenance, spatial data query and underground water resources assessment. After balance calculation, it is concluded that the total recharge and discharge amount is 151 804×104 m3/a, 162 612×104 m3/a, respectively. The multi-year annual mean underground water resource is 145 125×104 m3. Compared with previous study, the results are accurate and reliable and may provide a guidance for the water use in Yulin energy resources base construction. |
