Abstract:

Aims & Background: South Dianchi National Wetland Park, which is an important wintering and stopover site for migratory birds in the East Asia–Australia migratory corridor, was used as a research target. The wetland ecosystem has been degraded and the biodiversity declined due to the human activities such as the encirclement of the lake and the construction of wave breakwaters. 

Methods: This study conducted case analysis, describing how to protect the wetland ecosystem and repair the damaged wetland habitats and woodland habitats in terms of determining protection and restoration objectives, dividing ecological zones, removing wave breakwaters, connecting the water system, modifying the forest. In addition, this paper systematically summarized the experience accumulated in design, implementation, construction, operation and management of the wetland park and reflects on the key tasks that need to be strengthened in the future. The Jaccard similarity index and G–F index were also used to compare the changes in bird species diversity before and after park construction 

Results: After the completion, the biodiversity of the wetland park has been enhanced, with the Jaccard similarity index reaching 0.83 which shows high similarity in community composition and low disturbance of the original bird community by the park construction. The G–F index rose from 0.7 to 0.8, and the D_F index increased from 13.83 to 21.16. Both forest bird and waterbird populations have seen growth, with newly recorded species being predominantly winter visitor, original design intent has been realized. Suggestions & Perspectives: we suggest that the future work should be strengthened in the aspects of biodiversity monitoring and assessment, the formulation of wetland park management regulations and operation and maintenance etc.
