Abstract：Large-scale field infiltration test could avoid the scale effect of hydrogeological parameters application. Groundwater level lagging capacity has been analyzed based on the groundwater levels variation of 87 observation wells. The spatial and temporal variations of groundwater levels along the six cross sections show that, there is obvious lagging phenomenon, which affected by topography and infiltration locations; the analysis results of correlation between response parameters of groundwater level and distances show that, with the increasing of distance, the response time and the peaking time have a increasing trend, however, the arising ranges and arising speeds have a decrease trend; the contrast between the linear fitting results show that, the permeability order of aquifer is northern infiltration field (the best), central island and southern infiltration field ( the worst)
