Abstract:: The coordinated development of economy and ecology is the important foundation for sustainable development. Selecting 3 typical counties of Huangshui Valley of Qinghai Province, we constructed an index system of economy-ecology system. Then we used the coupling-coordination model to analyze economic development and ecological environment system coupling coordination and comprehensive development level from 2008 to 2015. Finally, we quantitatively revealed the coupling coordination degree of economic development and ecological environment, and analyzed the relation coupled spatial distribution and evolution from the space-time point. The results showed that: (1) economic development and ecological environmental system coupling and coordination degree raised in the Huangshui Valley during 2008—2015, while the coordination degree was between 0.429 4 and 0.743 8, generally presenting a moderate coordination of good coupling; (2) with respect to spatial variation, there were three states of coupling degrees in 3 counties of the Huangshui Valley in three different years, which were a primary coupling, intermediate coupling and good coupling；the coupling coordinative degree appeared 5 states: mild disorder, teething disorder, forced coordination, primary coordination and moderate coordination, the change of coupling coordination degree lagged behind the coupling degree; (3) with respect to spatial combination, there were 6 kinds of spatial combination types in three typical years in 3 counties of Huangshui Valley, which were primary-teething disorder, good-mild disorder, medium-teething disorder，good-forced coordination, good-primary coordination and good- medium coordination. In short, the contradiction between the development of ecology and economy is the main constraints for the overall level of coordinated development in Huangshui Valley. The results can provide the decision reference for improving the quality of comprehensive development in Huangshui Valley, coordinating the development of regional economy and the protection of ecological environment.
