[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.
