The Hydro-chemical Feature and Prospect on Utilisation of Shallow Groundwater in Hengshui

On the base of expatiation the background of hydrogeology in Hengshui area, the chemical character of the shallow salt water is explained by the classification methods such as Shoka Lev and SuLin according to the data of samples in the paper. We have discussed the genesis mechanism by using cluster analysis, factor analysis, hydro-geochemical parameters and geologic interpretation. It reaches conclusions that the types of water chemistry and its causes are complex in the research area; the shallow salt groundwater is the results of three types: affection of mainland salinity, seawater intrusion and human affection. The paper a view of the development and technical methods of utilizing shallow groundwater and make the contour map of the ratio between salt and fresh water with the test of samples. It can guide the agricultural production and has important practical significance.
