This thesis was supported by subject of "multi-objective geochemical survey in Hebei regional " component "water geochemical survey", investigate and evaluate water geochemical of shallow groundwater in Hebei Plain, and evaluate the quality of shallow groundwater.Through a great deal of field investigation, collecting 2,548 shallow groundwater samples, laboratory and analysis of its elements in 28 kinds. Drawing water geochemical chart by the analysis results of water quality on the various elements.Initially set the distribution of elements were determined by the types of the Landform through the water geochemical maps description. Setting 12 Profiles in the evaluation area, And further identify the impact of the type of landform on the ion content's high and low through analysis the ion's content.Analysis the distribution and evolution of geochemical elements of the shallow groundwater in the study area. Calculate the parameters of water geochemical using spss software. Analysis the portfolio characteristics of the elements by correlation analysis, cluster analysis and factor analysis, and separate the study area's geochemical zoning in accordance with the elements'high and low composition. Comprehensive study the conversion law and migration feature of the typical elements on the basis of the analysis of shallow groundwater and surface water, and the relevance of the surface soil. Evaluate the status's quality of the shallow groundwater in the study area, and evaluate the impact on agricultural production, living environment and endemic diseases, as well as provide the basis information for regional and local geochemical evaluation,and the ecological function of agro-ecological zoning. Establish early warning and forecast system of Hebei Plain's shallow groundwater on the basis of the comprehensive assessment, and making water quality status early warning on the study area, proposing rational utilization and protection of the development of viable proposals.
