By exploring the characteristics of land use change and the spatial evolution of Bayin River Basin in the past 10 years, we aim to provide the scientific basis for assessing the impact of social economy in this area. Based on Landsat TM remote sensing images in 2006, 2011 and 2016, the spatial and temporal change characteristics and driving forces of land uses in the study area were analyzed by using GIS, RS technology and principal component analysis. The results showed that:(1)from 2006 to 2016, the areas of cultivated land, bare land and saline-alkali land decreased by 0.56%, 2.8% and 5.32%, respectively, while the areas of water, residential land, forestland and grassland increased by 1.43%, 6.24%, 0.09% and 3.11%, respectively;(2)from 2006 to 2011, 84.14 km2 of cultivated land was converted into bare land and grassland; from 2011 to 2016, the area of residential construction land increased by 12.83 km2, which derived from bare land and grassland; the area of conversion of grassland to forest land was 2.2 times that of conversion of woodland to grassland;(3)from 2006 to 2016, the land uses in the Bayin River Basin were in the rational condition of development, and the change of the comprehensive index of land use degree was only 1.58 after 2011, which relieved the pressure of land use;(4)the changes of land use patterns in the Bayin River Basin were mainly affected by population growth, changed in regional industrial structure and mandatory implementation of government policies. The land use change of the Bayin River Basin in the past 10 years was a process of alternate expansion and reduction, but the land was in a state of rational development and utilization. As the main driving force, the social economic activities greatly influenced the evolution process of land uses. Therefore, how to coordinate and deal with the relationship between land uses and social economy in the future development process is particularly important.
