Study on Bird Diversity and Intelligent Monitoring Technology in Lake Wetlands:Taking Changdanghu Lake and Gehu Lake as Examples
To understand the bird diversity in the wetlands of Taohu Lake and Gehu Lake,and to compare the differences between traditional and intelligent monitoring methods in small-scale bird surveys,we conducted a survey of Taohu Lake(Changdanghu Lake)and Gehu Lake Wetland Park with traditional monitoring method(bird line sampling method and sample site method)from January to December,2023.During the survey,intelligent monitoring method was used to investigate two areas(Yushan Village area of Changdanghu Lake and Taxia area of Gehu Lake).A total of 156 bird species belonging to 16 orders and 51 families were recorded throughout the year,including 152 species in Changdanghu Lake and 103 species in Gehu Lake.Spatially,the bird diversity of Changdanghu Lake wetland was higher than that of Gehu Lake,and the Shannon-Wiener index,Simpson index and Margalef index were all higher than Gehu Lake.The Pielou evenness index of Gehu Lake was lower than that of Changdanghu Lake.In terms of seasonal distribution,the Shannon-Wiener index and Margalef index were at the highest level in autumn.Comparing the results of the two monitoring methods in the same area at the same time,we found that the two methods were roughly equivalent in the number of species.In terms of individual number and Simpson index,intelligent monitoring was significantly higher than traditional monitoring.In terms of Shannon-wiener index and Pielou index,intelligent monitoring was lower than traditional monitoring.The number of national important protected bird species found by intelligent monitoring was higher than that by traditional methods.Based on the above results,the influencing factors of bird characteristics in the wetlands of Taohu Lake and Gehu Lakes were discussed,and suggestions were put forward on the updating of bird monitoring methods and habitat protection.
