| The Shallow Groundwater Recharging Characteristics Responding to Human Activities |
| Through data preparation and analysis of the precipitation recharge, irrigating recursive recharge, seepage from rivers and canals and lateral infiltration recharge, the authors found out that the shallow groundwater recharge resource was decreasing year after year under the background of increasing human activities: the integrated recharge was reduced acutely from 21.6% in 1976-1980 to 11.3% in 2000-2005. On such a basis, this paper analyzed the shallow groundwater variation characteristics in answer to human activities, which included exploitation, flux and irrigation area flux. The relationship between the groundwater recharge and the exploitation is expressed as y=65.412x-0.2576, which implies that the exploitation is negatively correlated with the recharge. The relationship between the riverway leakage and irrigation flux recharge and the water amount increase tends to be positive but is different at different groundwater levels. This study is of great significance for the alleviation of the overexploitation of groundwater. |
