Ordos City is the most economically developed region in Inner Mongolia and even western China. However, the shortage of water resources has become an important restricting factor on economic development. In this paper, the water resources ecological footprint theory, LMDI model and Tapio elastic analysis were used to calculate the water resources ecological footprint and its influencing factors from 2001 to 2017, and to evaluate the coordination between usage of water resources and economic development. The results showed that: ① the water resources ecological footprint had shown a general trend of increasing with small fluctuation and then decreasing steadily. Among them, agricultural production consumption was the main component. And technical effect was the core driving force to reduce the water resources ecological footprint. ② Water resources ecological deficit, pressure index and the water resources ecological footprint of ten thousand Yuan GDP all presented apparent declining trend. Although the utilization efficiency of water resources increased year by year, the structure of the water resources utilization was not scientific and the water consumption of agricultural production accounted for a very high proportion. ③ There was a stable decoupling state between GDP growth and water consumption. Agricultural water decoupling was better than that of industry. The regression analysis showed the unstability of industrial water decoupling. Therefore, improving industrial structure and optimizing the proportion of water resources by the three major industries should be strengthened so as to reduce water consumption and achieve sustainable use of water resources.
