[Objective] The objective of this study is to analyze the relationships between the urbanization and urban construction land use in Kashgar City in Xinjiang Uygur Autonomous Region, in order to provide a scientific basis for long-term sustainable development.[Methods] Based on the statistical data, we analyzed the characteristics of urbanization and construction land use changes in Kashgar City, and examined the relationship between them during the period from 2009 to 2013 by using Grey relation analysis method.[Results] The changes of construction land use were obvious, and the ratio of town-village and industrial-mining land was the biggest in total land area. There was a significant relationship between urbanization and construction land use. The average correlation coefficient between non-agriculture population proportion, per capita GDP, urban built-up area, daily water consumption per capita and construction land were ranged from 0.65 to 0.85, which belongs to the strong correlation. The correlation coefficient between per capita park green space and construction land was about 0.35 to 0.65, and it was a moderate correlation. There was a strong correlation in the two-way average correlation coefficient values between urbanization and construction land use and they were greater than 0.65.[Conclusion] There is a strong correlation between the urbanization and urban construction land use in Kashgar City. Reasonable adjustment of population structure and size, balancing development of population, economy, space, society and environment, effective and reasonable use of limited resources and optimal distribution of land resources are the effective measures for sustainable development of Kashgar City.
