%X The driving forces of land use and land cover change (LUCC) are one of the main issues for LUCC research. LUCC is driven by both natural and socio-economic factors, but socio-economic factors have the most influence at local and short-term scales. In this paper, we analyze land use changes and their driving mechanisms in the context of a mixed agricultural and livestock production area in northern Shanxi Province. The study was based on Landsat TM images of 1986, 1993 and 2003 and methods from remote sensing, GIS and regression analysis. The results show that during the study period, comprehensive land use was relatively high, more than 36.5% in 2003. Land use declined from 1986 to 1993, while from 1993 to 2003, land use was in a phase of development and changes were drastic. The characteristics of land use change in the area included: woodland and built-up land area increased, while the total area of cultivated land, water bodies, unused land and sandy land consistently decreased. From 1986 to 2003, woodland area increased by 44.18×104hm2, mostly converted from grassland, unused land and cultivated land that was converted to woodland due to national policies on environmental restoration. These changes occurred in the southern loess hilly areas and in the sandy area in the northwest. With rapid economic development and growth of urban areas, built-up land increased at a rate of about 0.27×104hm2/a, and was converted primarily from cultivated land, grassland, unused land and sand. The area of cultivated land decreased by 10.52×104hm2, and was chiefly converted into woodland and grassland. The area of sand decreased steadily, to 20.67×104hm2. In terms of spatial distribution, land use changes were most obvious in the south and southeast of the loess gully-hilly region and the Mu Us desert edge. Natural factors, human activities and socio-economic factors were the main drivers of land use change. We conclude that climate was an important component of natural factors that drove land use change, while population pressure, socio-economic activities and agricultural and industrial industrialization directly affected spatio-temporal shifts of LUCC.
