| Abstract: | With the helf of GIS,dynamic changes of land use in Hefei are analyzed based on remote sensing images in 1995 and 2001.The results are as follows: the arable land in Hefei is generally decreasing,the construction land has grown in the trend,the forest land and lawns almost keep the same,and the water area is increasing relatively.At the level of landscape,the indices of shape and diversity are increasing,while dominance and contagion of landscape of land use in Hefei are generally falling. |
