【摘要】 2011-2012年采用样方法对呼和浩特东部地区4个样区的昆虫多样性进行了调查。共采集昆虫5305号,分属于11目,76科,共164种。主要的目有蜻蜒目Odonata(1)、螳螂目Mantodea(1)、脉翅目Neuroptera(2)、革翅目Dermaptera(1)、同翅目Homoptera(6)、直翅目Orthoptera(19)、半翅目Hemiptera(23)、鞘翅目Coleoptera(44)、鳞翅目Lepidoptera(16)、双翅目Diptera(29)和膜翅目Hymenoptera(22)。其中直翅目、半翅目、鞘翅目、双翅目、膜翅目为呼和浩特东部地区优势类群。经过全面调查,并结合Shannon-Wiener多样性指数、优势度指数、均匀度指数、密度公式等,系统地分析了呼和浩特市昆虫的群落组成,以及不同生境昆虫群落的季节动态等。依据调查区的植被类型,在调查区选择样地4块,分别为稀树草地2块,农田2块。其他4种生境昆虫的群落结构都有显著差异；表现为农田昆虫群落结构最复杂,稀树草坪昆虫群落结构较简单。4种生境的昆虫群落表现出明显的季节性差异。不同生境昆虫的日活动节律具有显著性差异。草地的昆虫日活动节律为双峰型,在早晚各有一次昆虫数量高峰；稀树草地的昆虫日活动节律为单峰型,在早上出现一次数量高峰,之后数量比较稳定；农田昆虫日活动节律基本为双峰型。更多还原

【Abstract】 Between January and December2011-2012, in order to approach the effects of different habitat types in Hohhot on insect diversity, an investigation was conducted on the insects in four types of habitats in Hohhot, Inner Mongolia. A total of5305insects were collected, belonging to164species,76families and11orders, among which, Orthoptera, Hemiptera, Coleoptera, Diptera, Hymenoptera were the dominant taxa.On the basis of a comprehensive investigation, combined with the Shannon-Wiener diversity index, evenness index, dominance index, density formula, the systematic analysis of Hohhot, the insect community composition in different habitats, different seasons, the habitat of insect Communities seasonal dynamics.According to the survey area vegetation types in the survey area to select plots4, respectively grassland2, farmland2. Community structure of the other four habitats of insects have significant differences.The performance of the most complex structure of insect communities in farmland, insect community structure is relatively simple in grassland.Significant difference existed in the activity rhythm of insects in different habitats. The activity rhythm of insects in the grassland showed bimodal distribution and quantitative climaxes existed in the morning and evening.更多还原
