Abstract
The dynamic of groundwater was comprehensiv ely studied with the observed data related to groundwater and meteorological conditions from 2005 to 2014 in Chifeng urban area. The results showed that the temperature and evaporation increased slowly, precipitation and sunshine decreased slowly in nearly ten years. Affected by human behavior factors and climate conditions, groundwater level was obvious downward trend year by year, declining rate at 1.15 m/year. In one year, the highest groundwater level was obvious in March, then began to drop month by month, until September fall to the lowest, and then gradually rise to reach the highest in March to the next year. For four meteorological factors, precipitation was very significantly negative correlated with groundwater, and the simple correlation coefficients was -0.507, temperature and evaporation significantly positive correlated with groundwater level, and the simple correlation coefficients were 0.653 and 0.708, which implied precipitation was the most important meteorological factors to promoting groundwater level (groundwater level decreases) , temperature and evaporation were the important meteorological factors to promote groundwater level declined.关键词
