Abstract: Wetland parks are built to protect the ecological environment of the wetland, the evaluation of the ecological function of wetland parks is important and the result depends largely on the evaluation index. The remote sensing ecological index (RSEI) was imported into our study for the ecological environmental evaluation of Nanhe National Wetland Park, Sichuan, China. As a result, the area proportion with 'excellent' or 'good' ecological environmental conditions of the wetland park is 24.37%, 48.23% and 59.07% before, during and after the building of the park, respectively, which imply an improvement of the wetland park. In total, 55.29% area of the wetland park's ecological environmental condition improves, most of which are forest areas. In the meanwhile, 19.41% area was deteriorated, which is mainly due to the construction of roads and buildings. This work shows that building a wetland park is a very useful measurement to improve the local environment.
