摘要：
Karst aquifers are characterized by highheterogeneity and spatial variability of their media. Time-series analysis of precipitation and waterlevel (as input and output functions), including correlation, spectrum analysis, were applied to the Jinan karst spring system in Shandong Province, in order to study the hydrodynamic behavior and hydraulic properties of the aquifer system. Autocorrelation and cross⁃correlation analysis showed that the sensitivity of the system to precipitation input signal decreased gradually from the recharge area to the discharge area, but the memory effect increased gradually. Phase analysis results show that the response of water level to precipitation signal in Jinan spring area lags behind. The lag time from recharge area to discharge area gradually prolongs, and the recharge area has better linear correlation. The results show that the quick flow accounts for about 20%⁃30% of the subsurface flow in the recharge zone, and the ratio is reduced to 2.5%⁃10.0% in the discharge zone. The fluctuation of water level in karst system is mainly affected by the internal structure of karstic medium. The karstification degree of the aquifer in Jinan is fairly low, and groundwater movement is dominated by matrix flow. © 2021, Editorial Department of Earth Science. All right reserved.
