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、mineral saturation index are calculated and some hydrogeological parameters such as hydraulic conductively,transmissibility,artual speed of groundwater、specific velocity and groundwater age 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.

依据已有水文地质和水质分析资料，运用地下水化学动力学理论和方法，通过水化学指标（组分活度α、矿物饱和指数β）的计算分析，结合有限的抽水试验资料，分区计算出渗透系数K、导水系数T、地下水实际流速U、渗透速度V和地下水年龄t等5项水文地质参数，定量的认识水文地质条件，认证了水源地泰康组承压含水层具有渗透性强、导水性强、地下水循环交替快、可更新能力强等特点。
