摘要

采用改进后的INFIL3.0模型计算鲁西北平原的地下水补给,分析灌溉和城市化因素影响下,地下水补给量的空间演化规律。计算结果表明:2001~2009年,鲁西北平原地下水补给量为105mm,补给系数为0.13,计算结果得到了验证。鲁西北平原地下水补给时空变异性较大。在时间上,地下水补给年际变化较大,呈增加趋势,年内有两个峰值,分别在4月和10月。在空间上,地下水补给由西北向东南增大,空间分布差异受灌溉影响显著。地下水补给量的空间演化结果显示,鲁西北平原存在一定的节水空间,城市化扩张会导致补给量减少,弱透水面面积增加10%,补给量较少10mm。模型计算结果可为区域地下水资源评价提供技术支持。

Abstract

The improved INFIL3.0 model is used to calculate groundwater recharge,and the spatial evolution of the groundwater recharge is analyzed under the influence of irrigation and urbanization in the Northwest Plains of Shandong Province. The results show that the groundwater recharge is 105mm and the recharge coefficient was 0. 13 from 2001 to 2009,and the results are validated. The spatial and temporal variability of groundwater recharge is large. In time,the inter -annual changes of groundwater recharge are larger,showing an increasing trend. There are two peaks during the year,respectively,in April and October. In space,groundwater recharge increases from northwest to southeast and spatial distribution is significantly affected by irrigation. The spatial evolution of groundwater recharge shows that there is some water-saving potential in the Northwestern Plains of Shandong Province. The expansion of urbanization will lead to a decrease in recharge. Weakly permeable area increase by 10%,groundwater recharge reduces by 10 mm. The calculation results of INFIL3.0 model can provide technical supports for regional groundwater resource evaluation.
