| 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. |
