Abstract:
On the basis o f analysis and study of spatia l distr ibution character istics of sha llow groundwa ter, th is paper studys rep lenishm en t, runoff and discharg conditions o f the sha llow groundw ater us ing isotope and hydro chem ishtry ana l?? ys is m ethods in Su??X i??Chang area. The ??D - ??18O% curve is established for phrea tic andm icro??confined underg roundw a?? ter by the ana lysis resu lts of hydrogen and oxygen isotope. A ccording to the ??D- ??18O% curve, ana lyzing the re lations o f the phreatic aqu ifer w ith r ivers, lakes and other surface w ater, and the evaporation deg ree o f m icro??confined g roundw a?? ter. The rep lenishm en t relations of m icro??confined g rounderwa ter and modern w ater are studyed by radio iso tope tr itium and 14 C. The problem of the sha llow groundw ate r replen ishment sources change is study ed by the conventiona lm ethod o f chem ica .l That synthetica lly ana ly ze the cond itions o f sha llow groundwa ter replenishm ent runoff and discharge com bining w ith groundwa ter leve,l litho logy, topog raphy and other aspects, in o rder to guide the rational deve lopm ent and utiliza?? tion of sha llow groundwa ter in Su??X i??Chang.
