Abstract:Restoring the ecological functions of damaged wetlands is an important part of the construction of the National Wetland Park, and restoration measures will have an important impact on the restoration effect. Dianchi Lake is an important wintering area for migratory birds in China. Due to long-term reclamation and urban expansion, the lakeside area has been severely damaged. In recent years, construction of wetland parks has brought opportunities for the restoration of Dianchi Lakeside, but the effects of various restoration measures still need to be clarified. In the winter of 2017, Kunming Southern Dianchi Lake National Wetland Park and adjacent wetlands were used as the study area, and four control sample areas were set up:constructed wetlands, enhanced wetlands, natural restored wetlands, and natural lake wetlands. Based on winter waterfowl diversity, the effect of wetland restoration was evaluated from the perspective of landscape ecology. The results showed that the natural lake wetlands had the highest species richness, followed by natural restored wetlands, enhanced wetlands, and constructed wetlands. Based on the Simpson diversity index, the waterfowl diversity of naturally restored wetlands was the highest (0.60±0.03), followed by natural lake wetlands (0.46±0.04) and enhanced wetlands (0.34±0.04), while the waterfowl diversity of constructed wetlands was the lowest (0.17±0.03), which showed that the effect of natural restoration was better than enhancement and reconstruction. From the perspective of landscape pattern analysis, waterfowl diversity was negative correlated with road area (r=-0.735, P<0.01), landscape shape index (r=-0.461, P<0.01) and landscape splitting index (r=-0.661, P<0.01). It also indicated that the degree of human disturbance, the shape of the landscape and the degree of fragmentation all had important impacts on waterfowl diversity. It is recommended that in the planning and construction of the National Wetland Park, the division of non-wetland landscapes, especially roads, on the overall wetland landscape should be reduced, and the connectivity and integrity of wetland patches should be improved to meet the spatial needs of waterfowl. Lake-type wetland parks should strengthen the creation of marsh in the lakeside area to meet the needs of waders, thereby increasing local bird diversity.
