1概述地下浅层咸水是指矿化度大于2g/L以上的地下水。又有微咸水和咸水之分。微咸水在河北的中东部平原,平面与浅层淡水相间分布,边界呈过渡状。水化学类型与浅层淡水近似,矿化度2~5g/L,咸水分布在中东部平原及滨海平原。咸水体顶板埋深0~80m,厚度自西向东逐渐加大,由50~100m,?
1 General Description Shallow shallow groundwater refers to groundwater with a salinity greater than 2 g / L. There are brackish and brackish water points. Brackish water in the plains of Hebei Province in the eastern, flat and shallow freshwater phase distribution, the border was transitional. Hydrochemical types and shallow freshwater approximation, salinity 2 ~ 5g / L, saline water distribution in the eastern plains and the coastal plains. Salt water body roof depth of 0 ~ 80m, the thickness gradually increased from west to east, from 50 ~ 100m ,?
