Changes of Bird Diversity in Different Habitats of Sanhuanpao National Nature Reserve
Understanding the current status of bird resources in nature reserves is helpful for understanding the envi-ronmental conditions of the reserves.In this study,different habitat areas of the Sanhuanpao National Nature Re-serve in Heilongjiang Province were taken as the research area,and the species and numbers of birds and their habi-tat factors in the study area were investigated and studied from March to September 2023 by using the sample line method,the sample point method and the song identification method.The results showed that a total of 3 929 birds were found in the research area,belonging to 16 orders,35 families and 72 species,including 2 species of national first-class key protected wild animals and 8 species of national second-class key protected wild animals,among which Passeriformes and Palaearctic birds accounted for the majority.After analyzing the relevant data of four habi-tats(namely water area,tidal flat,grassland and forest land),it was found that the Shannon-Wiener diversity index(5.052),Pielou evenness index(0.886)and Simpson dominance index(0.962)of birds in grassland habitat were all at the highest level.The similarity coefficient between water habitat and tidal flat habitat reached 0.658.Vegeta-tion condition,temperature condition and human activities have some impact on bird diversity of birds.It is sug-gested that the monitoring of birds in the reserve should be strengthened,the habitats of birds and rare wild birds should be emphatically protected,and the interference caused by human factors should be reduced as much as pos-sible.
