| 英文摘要 | Estimation of hydrochemical evolution as impacted by hydrodynamics processes at a regional scale has been a difficult issue for years. in this paper, typical index water-head (h), total dissolved solids (tds), and carbon-14 (c-14) data are collected from "baoding-cangzhou" and "shijiazhuang-dezhou" regional deep confined aquifers of the north china plain (ncp). (1) data analyses show that h-tds and h-c-14 have highly significant negative correlations along groundwater pathways of "baoding-west cangzhou" (pathway a-a) and "shijiazhuang-hengshui" (pathway b-b). average regression coefficients of h-tds and h-c-14 in different periods are about -12.76 (mg/l)/m and -1.266 (ka b.p)/m along a-a, -16.78 (mg/l)/m and -0.322 (ka b.p)/m along b-b. (2) interpreted via energy conservation, mass conservation and fractal geometry analyses, and proven by c-14 temporal data evidence, the tds temporal evolution equation is derived and confirmed in the natural groundwater flow region as , with average dissolution rates 10.45 and 54.13 (mg/l)/ka for a-a and b-b. (3) based on mass conservation, we deduce a governing equation for numerical simulation to calculate dissolution rate as determined by hydrodynamics. in this equation, only three parameters (h, tds and c-14) must be given in regional deep confined aquifers of the ncp. new practical and simple approaches of assessing the hydro-geochemical process in regional deep confined aquifers in the ncp are proposed. |
