| Abstract: | With the help of RS and GIS technologies and got landscape pattern indiced directly from Landsat TM/ETM images,the landscape pattern of Hefei was studied by using two phrases of Landsat TM/ETM images. The different change trends of shape index, fractal dimension and fragmentation index were revealed under the fast economy development and urbanization. Compared with the traditional methods, it was fast, exact, economical and easy method. And it was helpful to monitor the change of landscape pattern. |
