商丘市睢阳区直翅目昆虫的群落特征及多样性研究

Study on community structure and species diversity of orthoptera insects in Suiyang district of Shang qiu

在2015年9月、10月和2016年6月、7月间,在商丘市睢阳区选择了4种不同的样地,利用挖掘法、捕网法等方法,对当地的直翅目昆虫进行了广泛的采集和分类鉴定.共获直翅目昆虫500多头,隶属11科20属22种.利用物种多样性指数、丰富度指数、优势度指数、均匀度指数及相似性指数对所采集的标本进行了多样性分析.结果表明,荒地的多样性指数最高,物种丰富;而林区、草地因受植物的分布和人为干扰较大,物种较少多样性较低.

In September- October 2015 and June- July 2016, we collected the local Orthoptera insects widely by digging and netting from four different habitats and had a classification and identification. All 500 Orthoptera insects belonged to 22 species 20 genera 11 families. We studied the divesity of the Orthoptera insects in Shannon - wiener index, Margalef index, Pielou index, Simpson index and Jaccard Index. All illustrates that the wasteland had the highest species diversity , owning abuandant species, while the grassland, frostland and farmland＇s diversity were lower and had fewer species because of the vegetation＇s distirbution and human＇s disturbance
