Regional Environmental Performance Assessment Based On Psr Model-A Case Of Tianjin

Regional environmental performance assessment could measure the achievement of the environmental management effectively. It contributed to raise the level of government environmental management, and provided a basis for policy-making. On the basis of existing research, the paper adopted the PSR model and the thematic framework model to established Tianjin environmental performance assessment index system, and calculated the environmental performance level (EPI) of Tianjin from 2006 to 2010. The analysis showed that there is a substantial increase in environmental management of Tianjin on the aspects of environmental equality, efficiency of resource use, contamination control, and environmental infrastructure construction. The dominant indictors of EPI in Tianjin are urban ecosystem vitality, environmental equality, and efficiency of resource use. In order to improve the effectiveness of the EPA, the policy object system should be improved, and a complete data base should be established in the meantime of building and improving the system of regional environmental performance assessment.
