Abstract: Using DMSP/OLS, NPP/VIIRS and Landsat remote sensing image data, the average nighttime light index (ANLI) and ecological environment index (RSEI) are extracted respectively, and the coupling coordination degree model of urbanization and ecological environment is constructed to quantitatively analyze the coupling coordination development of urbanization and ecological environment in the study area from 2000 to 2015. The results show one belt, one road is the city's urbanization. The results show that:① The urbanization level of Urumqi city has been rising continuously for 2000-2015 years, and the implementation of the "one belt" and "ecological civilization" construction has promoted the urbanization development of Urumqi. ② From 2000 to 2015, the average ecological index increased by 0.119 8, with a growth rate of 30.14%. With the increase of the government's efforts to control the ecological environment, the ecological environment in the study area has gradually improved. ③ From 2000 to 2015, the coupling coordination degree of urbanization and ecological environment in Urumqi ranged from 0.568 3 to 0.627 3, and the coupling coordination degree maintained an increasing trend.

Key words: average night lighting index, ecological environment index, urbanization, coupling coordination model, Urumqi
