| 摘 要： | 采用巴氏灌诱法(陷阱法)对茂兰喀斯特森林4种林型的地表昆虫多样性进行研究.共采集昆虫标本9462个,有10目40科,其中鞘翅目(35.64%)和膜翅目(33.15%)数量较多,鞘翅目中数量最多的是步甲科,膜翅目中数量最多的是蚁科;在科级水平上,乔灌混交林的地表昆虫多样性指数和均匀度指数最高(分别为2.8604、0.8045),乔木林和乔灌混交林的地表昆虫相似性系数最高(0.8205);4种林型中地表昆虫个体数在季节上呈现夏、秋、春、冬依次递减的变化趋势. |

| Abstract: | Litter-layer insect communities in four kinds of habitats of Karst forest in Maolan were investigated by means of the method of Baraer traps.9462 specimens were collected in the investigation,which belonged to 10 orders and 40 families.In these specimens,Coleoptera and Hymenoptera were the most abundant groups(accounting for 35.64% and 33.15%,respectively).On family level,the diversity and eveness of mixed shrub forest habitat were the highest(reaching 2.8604 and 0.8045,respectively).Similaity coefficients of the habitats in mixed shrub forest and arbor forest were the most(0.8205).The individual quantities of litter-layer insects in different forest vegetation types decreased with the seasonal variation of summer,autumn,spring,winter. |
