| 摘 要： | 在分析定西市城区主要供水水源地内官-香泉盆地水文地质条件的基础上，对盆地地下水位历年变化规律进行了分析。分析表明：地下水位历年呈持续下降趋势，汛期7～9月降水补给地下水资源量增加，地下水位持续回升；5月、6月农业灌溉用水量加大，地下水位下降速率加大。通过地下水资源均衡计算，盆地地下水处于负均衡状态。并对引洮供水工程引水灌溉后的地下水动态作了趋势预测。

| Abstract: | The article is based on analysis on hydrogeological condition of the main water-supply source from Neiguan to Xiangquan Basin in Dingxi city and analyzes the pattern of groundwater changes over the years in the Basin.The result show a declining trend in groundwater level over the years,rainy season from July to September precipitation increased groundwater recharge,groundwater levels continue to rise.In May,June,to increase in irrigation water,the water table drop rate increase.Calculated through the balanc... |
