In order to deeply understand the status of urban green development in Shaanxi Province and provide useful reference for guiding urban green development in Shaanxi Province, we constructed an index system for evaluating the level of urban green development, and based on the panel data of 10 prefecture level cities in Shaanxi Province from 2008 to 2016, analyzed the spatial-temporal evolution of urban green development level in Shaanxi Province and its obstacle factors using TOPSIS model and obstacle degree model. The results are shown as follows. (1) On the whole, from 2008 to 2016, the green development of 10 cities in Shaanxi Province is at a medium level, and the trend of evolution is mainly fluctuating and rising. There are great differences in the level of each city, and there are many types of horizontal evolution trajectories. Among them, Xi’an belongs to the type of high-level steadily rising, with an increase of 27.7%, Yulin belongs to the type of steadily decreasing from high-level to low-level, with a decrease of 13.4%. The level gap between cities shows a trend of increasing gradually. (2) From 2008 to 2016, the number of cities at the first level decreased significantly, while the number of cities at the second level increased significantly, which evolved into a unique spatial pattern in Xi’an City. The backward cities are mainly concentrated in the east of Guanzhong and Southern Shaanxi Province. (3) The main obstacle factors of each city have little change in different years, but there are obvious differences among different cities. On the whole, the tertiary industry labour productivity, the secondary labour industry productivity, the number of college and university students per 10 000 urban residents, the number of buses per 10 000 urban residents and the per capita disposable income of urban households are the most important obstacle factors to Shaanxi’s urban green development.
