摘要
采用典型样地捕网调查方法,对整个山地主要放牧地区昆虫物种和群落进行分析,结果表明:鞘翅目(Coleoptera)、直翅目(Orthoptera AxeDgb)、鳞翅目(Lepidoptera)、膜翅目(Hymmenoptera)是构成宁夏香山荒漠草原区的主要昆虫类群;该地区的天敌昆虫数量较少,环境十分适合蝗虫类(Acrididae)和拟步甲类(Tenebrionidae)生存。而蝗虫类和拟步甲类对植被的取食,造成植被破坏,使得环境进一步恶化。
Insect species in typical plots in grassland vegetation were investigated by the net and identified undcr laboratory in the core product region of Zhongwei goat, Xiangshan Mountian, Ningxia. The results showed that there were mainly four insect groups （COLEOPTERA, ORTHOPTERA, LEPIDOPTERA, HYMMENOPTERA） in the plots, and natural enemies insect were very few, and then herbivorous insects were dominant insect group. Because of long - term arid and heavy distribution, arid environment was suitable for survival of grasshopper and Tenebfionidae that destroyed vegetation of arid mountain and recuhed in further detefiorateon of arid environment.
