Located in Liaodong Bay in the north of Jinzhou,Yingk-ou,Panjin City,and as the study area,the reference in the study area in 2007 land -use graphical data ,the three cities in Liaodong Bay,the nine northern landscape patch types were compared. The results showed that: (1) matrix Jinzhou dry landscape and woodland,the area ratio was 54.9%,18.9%,dry throughout the region,mainly in the central and woodland west. Panjin City landscape of paddy fields and wetlands matrix,the area ratio was 45.8%,22.5%,paddy fields covering most ar-eas in the eastern , western and wetlands are located in a small area in the south.Yingkou matrix landscape woodlands and dry , the area ratio was 49.8%,21.8%,woodland located in the Southeast, concentrated in the central and southern upland small area.(2)Jinzhou, Yingkou, Panjin City and landscape diversity indices were 1.40,1.52,1.33;landscape dominance index were 0.79,0.68,0.86;landscape evenness index were 0.64,0.69,0.61;landscape fragmentation index were 0.0087,0.0041,0.0061. (3)Jinzhou,Yingkou, Panjin City and regional ecological environment index were 0.36,0.42,0.51.
