摘要：
We studied the landscape change of Songpan County based on the RS images. Not only the conventional landscape index method was taken, but also Kappa coefficient was chosen to study landscape change. The results indicate the landscape fragmentation kept slow increasing, and the nature patches are still landscape matrix. The results of Kappa indices show that the qualitative, positional and integrated landscape changes are below 10% and different in three periods.
