%X An analysis of large quantities of information shows that main factors affecting groundwater vulnerability to pollution in the plain area are water_table depth, soil media, vadosezone bed and its characteristics, and that, of these factors in the vadose zone, the filtration capability of clayey soils is most important. It is demonstrated that the filtration capability of clayey soils can be obtained by leaching experiments and calculation, and that the adequate thickness of effective clayey soils can also be figured out. The capability for polluted groundwater consists of filtration capability and adequate thickness of effective clayey soils in the vadose zone. Groundwater vulnerability to pollution in the plain area may be evaluated by means of filtration capability and adequacy thickness.
