The relative concepts and prmi ary strategies of the cartograph ic generalization technology are summarized. And the research progresses andmain achievements in the field of car- tograph ic generalization technology are introduced based on the follow ing aspects: ( ) the estab- lishment of the know ledge bases and the reason ing process, ( ) model selecting andmodel bases building, ( ) generalization approaches and results assessment. Lastly, a framew ork formu lti- scale generalization technology of Forest D istribution M ap is d iscussed.
