To study the effects of climate change on landscape patterns at sites in Xanadu, wavelet transformation and remote sensing were used to analyze the climate change rules from 1981-2010 for landscape pattern dynamics in three different periods: 1990, 2000, and 2010. Results showed that the annual temperature had a rising tendency over the nearly 30 years with an interannual variation of 0.065·a~(-1) years. Zone temperature changes alternated between a low frequency of 30 years and high frequency of 10 years. Annual precipitation declined slightly with interannual variation of 0.07mm·a~(-1). The low frequency of 25 years experienced drought; whereas, the low frequency of 10 years alternated between wet and dry. Dominance of the grass landscape declined on this site. Structural landscape changes included a decrease in grasslands, water areas, wetlands, and swamps; while farmland, woodland, residential places, and sandy areas increased. For instance, sandy areas increased 9.55 km~2 in nearly 20 years. Over this 30 year period, climate change was not the dominant factor that changed the landscape pattern; climate change associated with sandy and grassland areas were greatest. As regional development and relevant eco-engineering being the main factors contributing to reduce stability of these landscape sites.
