The Study on the Structure of Avian Community and Species Diversity in Hohhot City in Spring

During the spring of 2004,studies were conducted to investigate the community and species diversity of spring birds community in Hohhot which includes seven different urbanization level habitats. In total,32 species,which belong to 19 orders,9 families,were recorded. Based on the principles of community ecology,we evaluate and discuss structural characteristics by means of the Shannon-wiener index(H′),species evenness(J),richness index in spring bird community . The results indicated that: the diversity index and species evenness in park and nursery are the highest in seven typical habitats,on the contrary,the diversity index and species evenness in shopping center and traffic occupancy are lower than others.
