Abstract: It is imperative to reevaluate groundwater resources in Qianjin source field, DaQing City where groundwater system has been changed since the 1980s as the result of intensive exploitation of groundwater resources. Based on hydrogeological data and groundwater chemical analysis data and the theory and methodologies of groundwater chemical dynamics in combination with limited pumping test data, some groundwater chemical index such as activity of component(α)、mineral saturation index(β) are calculated and some hydrogeological parameters such as hydraulic conductively(k),transmissibility(T),artual speed of groundwater(U)、specific velocity(V) and groundwater age(t) are also calculated zonally.The above calculation results are beneficial to quantificationally recognize the local hydrogeological conditions and to attest that the confined aquifer of Taconic formation has good permeability and transmissibility and t good renewal ability because of the active groundwater movement. This case can supply not only hydrogeological parameters for groundwater resources evaluation but also quantificational basis for sustainable and reasonable development and management of groundwater resources.
