Land use / land cover change (land use and land cover change, LUCC) is an important part of the global environmental change, and one of the important reasons causing global environmental change, has become the focus of attention of the global change research. Driving mechanism of land use / cover change, in particular, is the driving force of population growth and human activities are the focus of the current LUCC research. Case Study of Xi'an, Xi'an land in the context of economic development on the basis of analysis of Xi'an 2000-2005 land use status, use of the driving mechanism of the mechanism analysis, principal component analysis method, select Xi'an 2000 13 2005 impact of land use change related to socio-economic factors factor, input mathematical and statistical software SPSS principal component analysis, the analysis results show that the impact of Xi'an land use change in the socio-economic driving factors can be grouped into four categories economic factors, the factors of urbanization, industrial structure adjustment factors, demographic factors. The study showed that from 2000 to 2005 due to the country's western development strategy implemented by the field of real estate and other investment-led role, along with the rapid economic growth, Xi'an has a land area at the end of continuous downward trend, a decrease rate of 1.3 %. In order to reduce further shrinking of arable land, and curb other land use patterns of the occupation of arable land, you need to adjust the mode of economic growth. The intensive use of land conservation and land resources is an important part of the transformation of the mode of economic growth. The level of urbanization in the past few years increased by 41.54% to 44.91%, raising the level of urbanization has led to the adjustment of the industrial structure, so that the structure of land use change, mainly by industrial land, residential land and industrial land, urban land expansion lead to the reduction of arable land and agricultural land. Xi'an conversion of land use structure, enhance the function of land use in Xi'an, to some extent, to promote the changes in the industrial structure, Xi'an; Meanwhile, Change and upgrading of the industrial structure, promote the optimal allocation of land resources, especially the third the rapid development of the industry to effectively improve the efficiency of non-agricultural land. As the the Xi'an population continued linear growth, arable land is decreasing, but at the same time, residential and industrial land area of ??Xi'an and transportation land increased continually. Xi'an population between 2000 and 2005 from 6,880,100 to 7,417,300, the per capita arable land decreasing, from 0.74 mu / person in 2000, down to 0.64 acres / person in 2005, the people and land conflicts intensify. Based on current land use analysis and its drive mechanism, starting from the angle of the intensive use of land, the establishment of a land intensive use evaluation index system for Xi'an actual. And from the perspective of sustainable development has put forward suggestions six o'clock land use to play a reference role in the rational use of land resources in Xi'an.
