Abstract：
The non-relativistic potential models with color screening are employed to discuss the binding and deconfinement of heavy quarkonium.By means of the two kinds of parametrized potentials in a thermal environment,the screened lengths r are calculated.The results show that the screened lengths r^c_D depend on the potential behavior in the thermal environment.
