    摘要:

    大气降水入渗是北京市地下水补给的主要来源。为丰富地下水补给量计算方法,以基于遥感数据的水量均衡法对比传统的地下水位动态法评价求取降水入渗量。水位动态法计算北京市平原区2011年地下水垂向入渗补给量为17.39×108m3,遥感水量均衡法计算北京市平原区补给量为13.13×108m3,同面积区两种计算结果相关性R2=0.9631。两种计算方法各有其优缺点及适用条件。

    Abstract:

    The largest source of the groundwater recharge in Beijing is precipitation infiltration. The water balance method based on remote sensing was contrasted with the traditional water-table fluctuation method of groundwater resources assessment. The total recharge in Beijing plain in 2011 calculated by the former method is 13.13×108 m3 . The vertical infiltration recharge of groundwater in the plain calculated by the latter method is 17.39×108 m3 . The results show that they have very high correlation, R2 =0.9631. Both of methods have the applicable condition with the advantages and disadvantages.
