摘要
为了明确宁夏中部干旱带荒漠昆虫群落结构特征，2010年5～9月利用网捕法对宁夏中部干旱带6个不同生境昆虫群落的组成、多样性进行初步研究，总计捕获鉴定昆虫种类87种，隶属13目37科。研究结果表明，该地区昆虫以直翅目丝角蝗科、癞蝗科和鞘翅目拟步甲科为优势类群；经过对各生境昆虫群落的结构特征进行比较分析，不同样点多样性指数和均匀性指数由高到低依次为盐池、贺兰山、同心、白马、大青山、香山样带；不同月份多样性指数由高到低依次为7月、8月、6月、5月、9月。聚类分析表明，这6种典型生境中的昆虫群落明显地分为两种类型。
To reveal the structure characteristics of insect communities in the Arid Desert Ecosystems in Ningxia . From May to September in 2010,The community composition , diversity and ecological distribution at 6 sample belt were investigated in this arae .During the entire sampling period , 87 insect specimens were collected which belonged to 37 families .including 3 dominant families, i . e. Oedipodidae,Pamphagidae and Tenebrionidae;comparative analysis were conducted on the characteristics of the insect communities by Shannon Wiener diversity index （H′） , Pielou’s eveness （E） etc.The Shannon Wiener diversity indices in different sampling belts were in order of Yanchi sampling belt , Helan Mountains sampling belt , Tongxing sampling belt ,Baima sampling belt,Daqignshan sampling belt and Xiangshan sampling belt; the Shannon Wiener diversity indices in different months were in order of July,Auvip, June, May,and September.The results of cluster analysis and principal component analysis , basing on the composition of total insect , presented the six typical insect community obviously divided into two types
