There is an inherent link between urban expansion and urban land intensive use. The dynamic correlation between urban expansion and urban intensive land use is examined based on the urban expansion of Urumqi City in arid area, which can evaluate the city’s respons to land use pressure, in the period from 1990 to 2014, the expansion in Urumqi City presented a characteristic of slow extension to rapid expansion to intermediate speed expansion; in each period, the compactness of urban land was small, the fractal dimension was large, the construction of urban land distributed, the increase of urban land mainly depended on the inward filling. During the same period, the level of urban intensive land use had a characteristic of fluctuant rise, and presented a significant reduction in the last 10 years. The conclusion is obtained by using the correlation analysis. The intensification of urban land has nothing to do with the speed of urban built-up area expansion, but is related to the spatial form of urban land. The bigger the distribution and fragmentation degrees are, the more intensive the urban land development is. The coupling relationship between urban land expansion and urban land intensification can reflect the efficiency of urban land use and the response degree to land use pressure in a period of time. When urban expansion intensity is greater than land intensive utilization rate, land wasting phenomenon exists in the process of urbanization; when urban expansion intensity is less that land intensive utilization rate, the urban land utilization is efficient, but the advance of reasonable urban intensive land use should be carried out by following economic, social and ecological aspects as a principle.
