Abstract: As an important growth pole of urban economy, the level of intensive land use is directly related to urban economy and regional land sustainable use. In this research, the intensive land use in Urumqi development zone from 1993 to 2016 was evaluated by literature review, causal analysis, time series analysis, and analytic hierarchy process （AHP）. The results showed that Urumqi high-tech industrial development zone has developed rapidly since it was approved by the state council in 1992. The score of land intensity has increased from 39.42 in 1993 to 97.18 in 2014 and then fell back to 93.51 in 2016. Residential land gradually becomes the main land use structure in urban development zones. At the development end of urban development zones, there existed some phenomena, such as urban expansion surrounding the development zone, enterprise capital precipitation and declined land use efficiency. It suggested that Urumqi high-tech industrial development zone should be optimized under the guidance of Urumqi's overall urban planning. The improving of land use efficiency should be simultaneously followed by high-technic upgrading in new energy and new materials, inner industrial land improving and further optimizing the land use structure in the development zone.
