A Study on the Changes of Birds in 4 Parks of Jiamusi City in Different Seasons
In order to master the structural composition and varying patterns of birds in different seasons of urban parks in Jiamusi City,the author investigated four parks in Jiamusi City by using the line sampling method and pointing sampling method.The surveyed habitats included three types of hab-itats:trees,shrubs,and lawns,and analyzed the diversity and activity patterns of birds in different sea-sons.A total of 69 species of birds,belonging to 29 families,50 genera,and 11 orders,were observed and recorded in the survey.Among them,there are 29 species of birds in the Passeriformes order,with 60 species in summer and only 29 species in winter.The species diversity index and dominance index are highest in summer,and the evenness index is highest in spring.Through investigation,it is suggested that the park should increase the variety of trees and shrubs,build artificial nests,strengthen the pro-motion of bird protection,and raise human awareness of bird protection.
