Taking Xining City as the research area, the index system of coordinated development of urbanization and ecological environment in Xining City is constructed by combining qualitative and quantitative methods. The index and comprehensive index scores are obtained by using analytic hierarchy process and weighted summation method, and the coordination degree between urbanization and ecological environment in Xining City whose evolution trend is evaluated and analyzed is quantified by combining the coordination degree model. The results show that the urbanization level of Xining has been on the rise in the past 10 years from 2008 to 2017, and after the urbanization level of Xining has been improved, the eco-environmental quality index, although which has a characteristics of fluctuation, has been also on the rise as a whole. From the analysis of coordination degree, the coordination degree showed a downward trend year by year from 2008 to 2012, in which the coordination value in 2010, 2011 and 2012 were below 0.4, showing a moderate imbalance state; from 2013 to 2017, the coordination degree showed a rising trend year by year, and showed a relatively stable state.
