Abstract:: By using data derived from the 1978 MSS image and 1987, 1996, 2007 Landsat TM/ETM images and with the help of GIS, the land use change in arid area of central Ningxia Hui Autonomous Region was analyzed. At the same time, the driving forces of the land use change was identified by making use of the correlation analysis and principal component. The results showed that the overall trend of land use change in arid area of central Ningxia Hui Autonomous Region was in an enlargement of the areas of cultivated land, urban land, whereas sandy land area decreased 281 682 hm², an average annual increase rate grassland area was 0.17%, and area of forest land reduced nearly 30 000 hm² over 30 years. The land use information entropy indicating that the degree of disorder for land use system increased, and the structure of land use became complexity and diversity. It was considered that population, economic, regional socio-economic development degree, industrial structure, agricultural production, socio-input, government policy, and natural factors are the main driving forces inducing land use change in arid area of central Ningxia Hui Autonomous Region. More importantly, the principal component analysis showed that the impacts of human activity combining with some other conditions were the leading factors that induced dynamic change of the 1and use.
