Abstract:: We aim to analyze the landscape pattern characteristics by extracting the land use type information by the image data of Land Resources Satellite Landsat 8 in 2013 and using landscape pattern index and geographical spatial interpolation method. Representative samples were selected based on the landscape pattern analysis, and the landscape change was examined by moving buffer method. We hope to provide the references for land use, ecological environment protection and landscape optimization in the study area through this research. The resutls show that both landscape fragmentation and landscape diversity have the high distribution consistency in spatial distribution and gradient change. That’s to say, the values of landscape fragmentation and landscape diversity have the high correlation in geographical space. Landscape dominance shows different change characteristics in each sample zone, which are influenced by the size of landscape patches and land layout has a more effect on it. At last, landscape connectivity in every sample zone is high, showing a close connection between the same types of patches in the study area.
