Abstract: To study the coupling coordination type of natural resources, economy and ecological environment subsystems and the changing trend of their coupling coordination degree in the future in Urumqi City, with the help of coupling function in physics, a coupling coordination degree index system about natural resources-economy-ecological environment system was built. Quantitative analysis of coupling relationship among the three subsystems was conducted using the coupled coordination degree mathematical model and related calculation method based on the relative statistic data of Urumqi City from 2001 to 2013. Then GM (1, 1) prediction model was used to predict coordinated development trend of the next three years. The results showed that the overall degree of coupling coordination presented an upward trend in Urumqi City from 2001 to 2013, and its value was 0.279-0.502, increased from 0.279 in 2001 to 0.477 in 2013, but its value in 2013 decreased by 0.025 compared with that of 2012, transforming from barely coordination to the verge of disorder. Prediction results showed that in the next three years, coupling coordination degree of natural resources-economy-ecological environment system would be improved obviously, and the coupling coordination degree was 0.476, 0.495 and 0.516, respectively, and the coordination type would transform from disorder into barely coordination gradually.
