Abstract In order to carry out a large scale land remediation in coastal areas in Jiangsu Province, a method is needed for evaluating the remediation effectiveness quantitatively. Based on four coastal land remediation projects completed in the coastal areas of Jiangsu Province, 27 evaluating indices are chosen to cover four aspects such as capital investment, process management, project implementation and comprehensive benefits. Then a comprehensive evaluation model is established by using statistical methods and expert consultation. Finally, project comprehensive benefits are evaluated and the follow-up suggestions and measures are put forward to provide a scientific basis for benefit evaluation of land remediation in the coastal areas. The results show that the overall benefit of the 4 land remediation projects is significant, and most of the indices have met the requirements by the program, showing remarked economic, social and ecological benefits. Since there is a larger gap in value between the individual indices in each project, the comprehensive evaluation of effectiveness of coastal land remediation projects needs to be improved more substantially. These evaluation outcomes have provided a basis and reference for specific improvements in practice of coastal land remediation.
