In order to study the issues of groundwater pollution,on the basis of considering starting pressure gradient and moving boundary in low permeability pore,the authors has established the coupling mathematic model of groundwater pollution and seepage.The finite difference method is used to solve the coupling model,and the influence of starting pressure gradient on the distribution of groundwater pollutant concentrations is analyzed.The results indicate that the starting pressure gradient has an important influence on the groundwater pollution.It cannot be ignored when the issues of groundwater pollution in low permeability pores are studied.
