Abstract: Based on the theoretical research and the subdivision theory of the main functional regions，the index system of coordinated degree and benefit function were also established with the data from 2001 to 2010 of the cities and counties in Ningxia. The counties’ coordination development degree in recent 10 years was calculated by using the coordination degree model. The dynamic analysis was made based on the division of the main functional regions in Ningxia. The results showed that the coordination development degree was relatively low in Ningxia, which was between the primary coordination in primary development and the bare coordination in excessive development. The coordination development degree was not balanced in four main functional regions. Finally, the countermeasures were put forward with the purpose of promoting the coordinated development of economy and ecological environment in Ningxia.
