| 摘要: |
| 通过对北京西郊农场节水型农业示范区地下水资源的调节计算，建立了地下水动态预测模型，并得到了不同年份地下水的允许开采量。用此模型预测了2010年的地下水动态。预测结果表明：该地区地下水严重超采，按现在的开采水平到2010年地下水水位理深将达54．2m；节水灌溉可明显减缓地下水水位的下降。 |

| Abstract: |
| By regulating caculation for groundwater resources of the water-savingdemonstration area in Beijing Xijiao farm,a dynamic prediction model on groundwater isdeveloped and the capacity of groundwater, allowed to be exploited in different yearsare obtained. Using this model groundwater dynamic in 2010 is forecast. The resultsshow that groundwater resources is being seriously over-exploited, hidden-depth ofgroundwater level will drop to 54. 2m at 2010,and the descending of the groundwaterlevel can clearly be retarded by the economy-water irrigation. |
| Key words: groundwater resources,groundwater dynamic,allowable capacity of exploitation,economy-water irrigation |
