To grasp land utilization condition, this paper established a land-use performance evaluation framework with 20 indicators based on the investment level, economic benefit, social effect, ecological security and land use structure aspects. Then performance evaluation of Jiayuguan City land use from 2006 to 2015 was performed on the entropy weight TOPSIS method. Furthermore, the obstacle factor of Jiayuguan land use performance was diagnosed by the obstacle degree model. The results indicated that land use comprehensive performance in Jiayuguan showed an upward trend during the study period, the trend could be divided into 3 stages:low performance-medium performance and high speed growth-good performance and steady growth. Five rule hierarchy performances were improved. Investment and ecological performances showed fluctuating growth trend, economic and social performance showed the characteristic of continued growth, structure kept steady in good performance. The change of land use performance was in line with land use policies of Jiayuguan, which presented the land use policies was well executed. In terms of obstacle degree, the obstacle degree of economic performance was the maximum during 2006-2009, and thereafter society and structure became two key factors affecting land use performance. As for single index, in the Eleventh Five-Year Planning period, the most important factor affecting land use performance was average controllable per capita income of city residents, but it became the proportion of public facilities land in the Twelfth Five-Year Plan period. So, Jiayuguan government should pay more attention to the fair allocation of resources and explore intensive efficient and equitable land use pattern actively.
