The results showed that the coordinate degree of Lanzhou's environment and economic development belonged to the type of coordinated development and its developmental level rose steadily year by year. 2000-2001 was the primary type of coordinated development; 2002-2005 was the intermediate type of coordinated development; 2006-2007 was the well-coordinated developmental type; 2008-2009 was the high-quality type of coordinated development of. In addition, the level of economic development in 2009 was higher than that of environmental development, and the remaining years the level of economic development lag behind the level of environmental development.
