Abstract: Species abundance pattern plays an important role on community structure. So far, less attention has been paid to abundauce pattern in ecology study. Study on abundance patterns started in 1930s′ and has had a great development during the past decades. Many descriptive models of abundance patterns with different features and performances have been established. The combination of species abundance and species diversity indices is more meaningful than treat them separately in community studies. Some points in species abundance pattern study need to be discussed and viewed.

Key words: abundance pattern, abundance rank, abundance distribution, community structure, species diversity
