Abstract:
Yingwuzhou Wetland is an important ecological node on the land and sea ecological corridor on the north bank of Hangzhou Bay characteriaed by human utilization and biodiversity protection. Since its construction over more than 5 years, bird diversity in the wetland has increased significantly, attracting a large number of tourists for nature-friendly recreational activities. In this study, we used the transverse-line method to investigate the bird resources and plant habitats and birds’ preference for plant habitats in combination with the distribution of birds in each habitat in the wetland. The relationship between the area accessible to tourists and the range of bird stampede in the wetland was also analyzed to explore the impacts of human disturbance on bird diversity. Four seasonal observation results showed that 720 birds of 33 species, belonging to 9 orders and 22 families, with the majority of the species belonging to the order Passerines, among which finch species were the most abundant, and the waterfowl accounted for a higher proportion of non-finch species. The number of bird species in wetland in each season was in the order of winter, spring, autumn and summer. The bird diversity index of each plant habitat was different, which indicated that there were differences in the bird attraction effect. The superposition analysis of the visitor-accessible area and the range of bird stampeding in the wetland revealed that the zoning control of the visitor-accessible area could reduce the probability and degree of disturbance of the birds’ habitat due to anthropogenic activities.
