| 摘 要： | 依据咸阳城区1985~2003年地下水位监测资料,对其地下水位变化动态进行分析。认为本区地下水位年内季节变化明显,年际变化持续或波动下降。人工开采等人为因素是影响地下水位变化的主导因素,降水量、蒸发量、水文地质条件等自然因素成为影响地下水位变化的次要因素。在目前供水和用水条件下,GM(1,1)模型模拟和预测的未来地下水位呈下降变化趋势。

| Abstract: | According to monitoring data of groundwater level from 1985 to 2003 in Xianyang city,authors analyze and think that changes of groundwater level are obvious in the seasons of year,and that annual change continues or fluctuant descends.Anthropogenic factors are primary influential factors of groundwater level variation,especially artificial exploitation;and amount of precipitation,amount of evaporation and hydrogeological condition are minor influential factors.Authors apply GM(1,1) model to simulate and forecast downtrend of groundwater level in the future on the condition of current water supply and water utilization. |
