摘要
2007年5～10月,通过对银川市黄河湿地保护项目区内昆虫群落的调查表明,宁夏银川市黄河湿地的昆虫共有9目81科233种。在12297号标本中,双翅目、直翅目个体数量较多,而双翅目和膜翅目的物种数较多。样地昆虫种-多度曲线符合对数级数模型,表明黄河湿地银川段环境质量较差。昆虫群落季节动态变化和多样性指数的变化说明7月份昆虫个体数量和种类数最多,同时群落多样性指数最高,群落最稳定。
An insect investigation was carried out frOln 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 the highest in July.
