Abstract Based on the GIS and RS techniques and the Landsat TM/ETM data and applying the principle of Landscape Ecology and the technique of GIS, the authors studied the dynamic change of the landscape pattern from 1991 to 2000 in Yanchi County of Ningxia, one of the typical farming-pasture ecotonal areas in China. It is concluded that the areas of all types of landscapes in Yanchi increased or decreased to some extent, that the landscape pattern was at the unstable stage, with the pasture remaining the eco-landscape matrix, and that the principal landscape pattern was still characterized by the farming-pasture ecotone.
