Abstract: [Objective] This article aimed to explore the social and economic characteristics of gradient change of land use landscape pattern in Guiyang. [Method] The calculation of landscape pattern index and the analysis of landscape gradient were combined to research the urban-rural, population density, traffic gradient changes of Land use landscape in Guiyang in 2000, 2010. [Results] ① In landscape types, with the distance from urban, traffic and population density, the area, proportion, broken degree and shape complexity of various landscape types of land use presented certain trends of change in gradient zones of each size. ② In landscape levels, along the gradient direction of urban-rural, traffic and population density, the fragmentation degree of land use landscape changed from big to small, the area of overall landscape type tended to equilibrium, the separation degree decreased and the aggregation degree enhanced. [Conclusion] The social and economic gradient of land use landscape in Guiyang city changed obviously. The policy of returning farmland to woodland, grassland and the urbanization development are the leading factors of the social economic gradient change.
