| Abstract: |
| Guanzhong basin is the most economically prosperous region in West China,but the further growth of its economy is constrained because of the shortage of water resources.Based on geological and hydrogeological conditions,the paper evaluates and analyses groundwater resources from the point of factors that affect the formation of groundwater.The results show that natural resources of groundwater(5.39×108m3/a) and available withdrawal of groundwater(4.53×108m3/a) have decreased greatly under natural factors and human activities.North to the Weihe River,the main factors affect the formation of groundwater are precipitate infiltration and irrigation leakage which amount for 83.9 percent of total recharge.However,south to the Weihe River,94.2 percent of total recharge comes from precipitate water and river leakage which are chief factors of the formation of groundwater.On the basis of research mentioned above,the paper puts forth the countermeasures to develop and utilize water resources reasonably,which is important for sustainable use of water resources and benign circulation of the eco-environment. |
