The urbanization is the necessary way for the economic development of a country or region and at the same time one of the important signs to measure the level of economic development in a region. This study focuses on the urbanization in Turpan area to analyze the situation and the coordination of the urbanization development in the oasis of the arid area. By building the index system of urbanization in population, economy, society and ecology system including 16 evaluation index and using the entropy-based weight to determine the weight of each index, with the weighted sum of the Turpan area in 2001-2011, the urbanization of the composite index were quantitatively analyzed. Based on the situation of urbanization, the coordination of the urbanization is calculated and the future development trend on the mathematical models is predicted. On this basis, the development trend of Turpan area in the future is predicted with linear-regression analysis method and trend extrapolation method. Through the above information, the main driving force and the restricting factors of urbanization development in Turpan area can be found. Then, the specific suggestions and opinions in the development of the urbanization in Turpan area, even in the arid area are put forward. The innovation of this study is the study area located in the arid zone in oasis area and then the calculation of the coordination in the urbanization development process. Therefore, a more in-depth understanding of urbanization in the arid zone in oasis area is achieved.
