Abstract: Using area transition matrix and landscape indices,the change of red-crowned crane (Grus japonensis) breeding habitat in Shuangtaihekou National Nature Reserve was analized.The results showed that the area of red-crowned cranes breeding habitat was reduced while the heterogeneity and the fragmentation was increased.The change of the habitat quality can directly cause the change of the number breeding of red-crowned cranes.The number of breeding red-crowned crane in Shuangtaihekou National Nature Reserve was reduced from 1989 to 1998,mainly due to the activity of human beings,such as road construcition and oil drilling.
