Abstract:Based on the landscape ecological principles and methods,and using eight landscape pattern indices (landscape diversity index,evenness degree index,separation index,isolation index,fractal dimension index,and connectivity index,etc.),this paper analyzed the urban greenland landscape pattern in Shenyang. Overall,the green space had a lower proportion,its distribution was disproportional,and the structure of greenland system wasn爷t reasonable. The separation index was high,the fractal dimension was low,the landscape types were rather com鄄 plete,the even
