Abstract: This paper took Urumqi, a typical oasis city in Northwest China, as an example, using mathematical statistics and spatial statistical analysis. It selected three time periods, 2004, 2011, and 2018, to analyze the speed and direction transformation, the distribution of the spatial pattern, and the shift direction of the focus of Urumqis “production, living, and ecological space” land use functions in terms of time sequence, exploring the factors that lead to its transfer, and the optimization suggestions. The living and production space of Urumqi City showed a trend of concentrated and sharp outward expansion, with an increased area of 437.91 km2. Its focus was on the city center with the shortest transfer trajectory. The development in the early and late stages continued to exceed the depletion rate, and the occupied areas were 131.43 km2, 194.82 km2, and 18.47 km2, respectively. The ecological space showed a shrinking trend, which slowed down the transfer rate in the later stage as the awareness of environmental protection gradually increased. Due to the fixity and difficulty of restoration of the natural resources, the mutual transfer of various types of land in this space has become the main direction, and the largest increase in the volume of forestland was 206.99 km2. The space was in ecological restoration period, which remained to be a future direction that needs to be paid attention to. Its production and ecological space were distributed in a patch shape. After the appropriate adjustment to the land use structure in the later period with an area of 798.66 km2, the focus of the cultivated land reversed in the later period, and the development rate of garden plots rose sharply to 8.30%, coordinating moderately with the connection to living and production space structure. The ecological and production space was distributed sporadically, and the speed of transformation showed a fluctuating decline. In this case, based on the perspective of “production, living, and ecological space,” this research has suggested coordinating the diversified land ecosystem of Urumqi and improving the overall benefits of land resources and the level of sustainable development.
