日照砂质海岸生态系统鸟类多样性调查与分布OA

In order to better grasp the present situation of bird diversity distribution in sandy coastal ecosystem,during the period of 2020-2021 in bird migration,birds in four representative habitat types of the Rizhao sandy coastal ecosystem,including Liangchenghekou National Wetland Park,Wanbao Coastal Scenic Area,Rizhao Coastal National Forest Park,and Xiushui River Estuary were investigated by line tran-sect method and sampling point method.A total of 61 bird species were recorded,belonging to 12 orders and 19 families,including 2 species of national first-class protected animals;and 8 species of national second-class protected animals.The resident type is mainly migratory birds and summer birds;the animal fauna is dominated by widely distributed species.Among the four habitats,the bird diversity index of Li-angchenghekou National Wetland Park was the highest in 2020(2.59),and the bird diversity index of Xiushui River Estuary was the highest in 2021(2.37);the evenness index of birds in the Xiushui River Estuary has been the highest for two years(0.84 and 0.79);the bird domi-nance index of Wanbao Coastal Scenic Area has been the highest for two years(0.46 and 0.37).The investigation has enriched the basic in-formation of regional birds,providing scientific basis for the protection and management of sandy coastal ecosystems.
