As the shrinkage and degradation of coastal wetlands pose a serious threat to global bird migration, restoration of the degraded or constructed wetlands has become an important content for the coastal wetland protection. Tianjin Lingang Constructed Wetland (Phase Ⅱ), a typical coastal constructed wetland in north China, was taken as a case study for the restoration strategy of constructed wetlands, with respect to methods for determining biological community rapid reconstruction targets and suitable community species list. The other adjacent Beidagang Wetland Nature Reserve and Lingang Constructed Wetland (Phase I), with similar salinity as Lingang Constructed Wetland (Phase Ⅱ), were selected as alternative reference wetlands. The results of field investigation in 2019 showed that there were 110 species of phytoplankton and 28 species of zooplankton with only one species of macro-zoobenthos, while no fish were found in Lingang Constructed Wetland (Phase Ⅱ). It was indicated that aquatic organism species structure was too simple to afford adequate food supply for migratory birds. The investigation results also showed that East District of Beidagang Reservoir, West District of Beidagang Reservoir, and Lingang Constructed wetland (Phase I) had a higher biodiversity of phytoplankton, zoobenthos and fish than those in Lingang Constructed Wetland (Phase Ⅱ), and they could serve as the reference wetland. Since Lingang Constructed Wetland (Phase Ⅱ) has a not bad diversity of phytoplankton, only zoobenthos and fish resource need to be restored. Taking into account the food needs of the fish after recovery, the zooplankton can be released simultaneously. Based on the investigation & literature data of the reference wetland, zoobenthos restoration targets were determined as follows. Shannon-Wiener index will reach 1.58 in the coming 5 years and 3.00 in 10 years. The biological density will be increased to 300 ind./m² in the coming 5 years and 600 ind./m² in 10 years. Meanwhile, restoration species list for biological community rapid reconstruction, including 15 species of zoobenthos and 14 species of fish, was recommended and the roadmap for food chain reconstruction was also put forward. Our results suggest that, in terms of restoration of a degraded or constructed wetland in coastal area, natural wetlands with similar characteristics in the same or adjacent area can be selected as alternative reference wetlands, and biological survey & biodiversity comparison are helpful for the determination of reference wetland. Once the reference wetland was determined, the targets, and the suitable species for rapid reconstruction of the biological community could be proposed with the comparison between the reference wetlands and target wetlands.
