Landscape classification is premise and foundation for deeply research of landscape ecology. At present, it is lack of mature landscape classification system. Geographic genetic and Human activity is the essence of landscape formation and evolution of land surface. In this paper, based on the geographic genetic, in terms of the theory of physical geography, climatology, geological geomorphology and ecology, the author established a four-level landscape classification system. The first level, the landscape zone, based on climate zones. Climate zone determines the distribution of natural heat and water; The second level, the landscape region, is Drought index, reflecting the latitude and longitude zonality; The third level, the landscape classes, based on the elevation of geomorphic, which embodied the vertical zonality; The fourth level, the landscape type, come from the vegetation and landuse contained natural ecosystem and human activity. Using this system, we have classified the landscape in Xinjiang area, and divide the 3 landscape zones,4 landscape regions, 2 landcape classes and 11 landscape types. The results can provided some background references for researching on causes, evolution, recovery and reconstruction of regional landscape. This system could be applied into any terrestrial area of global.
