Abstract:An insect investigation was carried out from May to July 2007 in the Yellow River wetland in Yinchuan, Ningxia. There are 233 species, 81 families and 9 orders of insect. The individual numbers of Diptera and Orthoptera are more than other orders, but the species of Diptera and Hymenoptera are dominant. The curve of species-abundence is according with logarithmic model, which indicates that the environmental quality of the Yellow River wetland of Yinchuan is worse. The seasonal dynamic of insect community and the change of diversity index imply that the highest number of individual and species occur in July. Moreover, the diversity index and the stability of insect community are highest in July.
