中文摘要:
      选取2000-2014年玉符河流域4组孔隙含水层、岩溶含水层水位监测数据及同期济南市降水量数据,采用连续小波变换和交叉小波变换对地下水位与降水量的时滞进行分析。结果表明:相同地段不同含水层的水位变化规律较为一致,降水量和地下水位存在约1a的连续主震荡周期。自上游到下游,地下水位与降水量的时滞逐渐增大,岩溶水位与降水量的时滞为73.22-117.99d,孔隙水位与降水量的时滞为75.00-127.52d。对于相同地段不同的含水层,岩溶水位对降水的时滞整体上小于孔隙水位对降水的时滞。
英文摘要:
      Based on the water level monitoring data of 4 pairs of porous aquifers and karst aquifers in Yufu River Basin from 2000 to 2014 and the precipitation data of Jinan city, the time lag of groundwater level and precipitation were analyzed by continuous wavelet transform and cross wavelet transform. The results showed that the water level changes of different aquifers in the same area were consistent, and the precipitation and groundwater level had a continuous main oscillation period of about 1a. From upstream to downstream, the time lag of groundwater level and precipitation increased gradually. The time lag of karst water level and precipitation was 73.22-117.99d, and the time lag of porous water level and precipitation was 75.00-127.52d. For different aquifers in the same area, the time lag of the karst water level to precipitation was less than the time lag of the porous water level to precipitation.
