Abstract:: Based on emergy analysis, the development of circular economy in Qaidam basin is evaluated from such five aspects as emergy flow,emergy economy, resource input and output,environmental pressure and comprehensive index. The paper analyzes the condition of the development of circular economy in Qaidam basin from 1998 to 2007. The results show that the development of economy mainly depends on the nonrenewable resources and it is a region of resource out-putting. As a result, pressures on resources and environment in Qaidam basin are more and more serious, which means that Qaidam basin is a poor sustainable region. Therefore the future development of circular economy in Qaidam basin should make great efforts on properly exploiting and utilizing nonrenewable resources and improving the level of recycle use in order to promote the development of circular economy in Qaidam basin.
