Emission reduction has made a major breakthrough during the Eleventh Five-Year Plan period，due to the effective implementation of emission-reducing projects，structural emission reduction and monitoring for emission reduction in all cities throughout the nation；as a result，as a whole，urban environmental quality was improved and the ecological environment was stable in these cities. However，urban eco-environmental protection is still facing severe challenges in the future.
