| Abstract: | The existent problems of square root model in cartographic generalization are discussed. The laws that quantitative indexes of cartographic elements change with scale are explored,and the fractal transformation models of square root law,which can give consideration to the shape features of cartographic elements themself,are proposed based on fractal theory. They can give a new solution for quantitative choosing in cartographic generalization scientifically and objectively. Lastly some concret methods of cartogrphic generalization and actual examples to apply proposed models are given. |
