Abstract: As more and more attention has been paid to the problems of land resources in China, land use performance evaluation has become a synthetic method to evaluate the rationality and effectiveness of regional land resource allocation, which is helpful in quantitative analyses of land use. From the economic benefit, social effect and ecological security aspects, this paper selected 16 indicators to establish a land-use performance evaluation framework. Then, performance evaluation was performed on the land-use based TOPSIS method in the Shunyi District from 1996 to 2010, in which weights of indicators were determined by an entropy-weighted method. Furthermore, key impact factors on land-use performance were analyzed via grey correlation analysis. The results indicate that 1) Land use performance in Shunyi District showed an overall growth trend from 1996 to 2010. That trend can be further divided into a steady and modest growth period from 1996 to 2000, in which Shunyi took its industrialization course; and an accelerated growth period from 2001 to 2010, in which Shunyi showed high-speed development based on former primitive accumulation on the background of urbanization and new industrialization modes. 2) The economic coefficient of land performance grew slowly from 1996 to 2002, with a more dramatic increase since 2003. The social effect coefficient of land-use performance reflects the changes of land resources per capita, which was steady from 1996 to 2000 and decreased evidently in 2001, but showed an upward trend from 2001 to 2010. The ecological coefficient of land performance steadily changed from 1996 to 2000, and decreased from 2001 to 2005, but alternated up and down in the period from 2006 to 2010. 3) Changes of land-use performance reflect the sound execution of key points of land use policies in corresponding “Five-year Plan”. 4) Social and ecological factors of land-use performance have more impact on overall land use, and urbanization is dominant among all impact factors. 5) Industrialization is the main driving force for the increase of economic benefit of land-use performance. Urbanization becomes the key issue concerning societal development and fairness, because of its high relation with rapid changes of land resources per capita. Land for ecological use is the dominant factor on ecological performance of land use under the pressure of resource and environment. Finally, the study indicates that the TOPSIS model based on an entropy weighting method is effective because of the clear thinking and rational calculation for land-use performance. Intensive land-use, spatial carrying capacity of land for ecological use and environment protection shall be highlighted in the land use planning of Shunyi District. The analysis results are helpful to examine whether land use policies are enforced, and provide methods and ideas for the comprehensive evaluation and the optimal allocation of regional land resources.
