Abstract:

Stratified sampling method, macro-group classification method, and statistical method were used to study the community composition and structure of soil insects in seasonal wet meadow in Zhalong wetland. A total of 4 974 insect specimens were collected, which belonged to 13 order 73 families and 134 species. At the level of order, the individual number of Diptera, Coleoptera and Collembola was absolutely dominant (respectively accounting for 41.7%, 27.1% and 16.7% of the total number of soil insects). The characteristics of horizontal structure of insect community showed that diversity indexes and evenness index in Yuweichang were maximum, richness index in Yantongtun was maximum, in which diversity index, evenness index and richness index of large soil insects in Tumutai were maximum, while the three index of small and medium-sized soil insects were maximum, and the three index in Guanliju were minimum. Cluster analysis showed that four sample plots were divided into three classes.The insect communities in Tumutai and Yuweichang were more similar, and they shared one class.The other two plots each formed own class. The seasonal dynamic of insect community showed that species and individual number in July and September were relatively more, while those in May and November were less. The diversity index and evenness index in July were the maximum.The correlation analysis of diversity index, evenness index and richness index showed a positive correlation. Species-abundance analysis showed that insect community distribution in Guanliju, Yantongtun and Yuweichang conformed to a logarithmic normal distribution, while the insect community distribution in Tumutai conformed to a logarithmic series distribution.

Key words: soil insects, community structure, clustering analysis, species-abundance distribution, Zhalong wetland
