[Objective] To discuss the spatial-temporal variations of urban landscape pattern in Taiyuan City in different scales, and expected to provide an important scientific basis for explaining the spatial-temporal pattern of landscape pattern evolution in the process of urbanization and evaluating the impact of social-economic development.[Methods] The research was based on 3 time series of Landsat TM remote sensing images from 2000 to 2015. We used the spatial distribution of land use in level 1 of landscape types, and used Fragstats 3.4 software to calculate the landscape pattern characteristic index in Taiyuan City, studied the temporal and spatial variation of the urban landscape pattern in the whole city and the main urban area of Taiyuan City. And then we analyzed the driving effect of landscape pattern in Taiyuan City used SPSS software system.[Results] ① In the past 15 years, woodland, cultivated land and grassland have always been the main landscape types in the whole city. The proportion has changed from 33.60%, 31.80% and 27.47% to 35.18%, 27.97% and 25.49% respectively. The area of urban-rural, industrial-mining and residents land increased significantly. The proportion increased from 5.86% to 10.27%, among which cultivated land and grassland were the main sources of the expansion of urbanization land. Land use intensity in the main urban area showed an increasing trend. The proportions of urban-rural, industrial-mining and residents land increased from 21.65% to 33.82%, became the main landscape types in the main urban areas, and the proportion of arable land decreased from 27.04% to 37.54%, the amount of cultivated land occupied by urban-rural, industrial-mining and residents land was more visible than that of the whole city. ② In the whole city scale, The patch fragmentation of cultivated land and woodland is high, the landscape contagion decreased, landscape diversity increased. In the main urban area scale, however, urban-rural, industrial-mining and residents land fragmentation degree increased, landscape contagion increased after an initial decrease, but the landscape diversity decreased after an initial increasing trend.[Conclusion] Urban landscape pattern in the whole city are different definitely with which in the main urban area of Taiyuan City. Social-economic development, policy factors, and the phasing regulation role of urban planning and development theory are main driving forces of the evolution of urban landscape pattern in Taiyuan City.
