This paper, based on landscape ecology theory and fractal theory etc., analyses the graphic information for land use pattern and its change using GIS technology. The study area was Changling County in Jilin Province. Fractal dimension of patches, shape index and isolation index were measured to master the land use spatial pattern in Changling County. It was found that there was fine pertinence between the shape of land use patch and land use type or its spatial pattern. So it could say that studying the patch shape of land use type would contribute to the land use change driven mechanism research.
