摘要
Based on attributes of pore confined water, the authors studied dynamic ( water level and quality) groundwater monitoring data and hydrogeological conditions of pore II confined water under over extraction in the periods of maximum water burial depth in the years of 1994 and 1998 in Su-Xi-Chang region. Hydro-chemical parameters could reflect the spatial variation rules of different water source supply, their ionic intensity (I) and major ionic activity (aHCO3- , aNa+, aCa2+)parameters calculated by constant water chemical components (K+, Na+, Ca2+, Mg2+, Cl-, HCO3-, CO32-, SO42- )divided the range and scope of seepage side pressure supply by Yangtze River, side supply by atmospheric precipitation and weak sealing well supply. The study provided bases for the deepening of extraction conditions of pore II confined water, evaluation of minable resources and dynamic prognosis of groundwater level.
