摘要
为明确管涔山昆虫多样性的海拔梯度格局,以管涔山3个不同海拔垂直梯度为研究样地,研究了不同海拔梯度上昆虫多样性的分布格局。结果表明:中海拔生境样地下的昆虫物种数最为丰富,有昆虫10目22科,优势种为膜翅目、半翅目和鳞翅目,优势度指数约为0.38,相对多度分别为19.03、18.88和17.74;该海拔下昆虫丰富度指数、多样性指数、均匀度指数和群落复杂性指数也均最高,分别为2.92、3.07、0.99、5.42;而低海拔生境表现出最高的优势度指数(0.33)。综上所述,管涔山海拔高度差异是影响昆虫群落结构的重要因子。
In order to clarify the altitude gradient pattern of insect diversity in Guanceng Mountain,taking three different altitude vertical gradients in Guanceng Mountain as the research sample,and the distribution pattern of insect diversity at different altitude gradients was studied.The results showed that the number of insect species is the most abundant in the middle altitude habitat sample.There are 10 orders and 22 families of insects,and the dominant species are Hymenoptera,Hemiptera,Lepidop-tera,with the dominance index of about 0.38 and the relative abundance of 19.03,18.88 and 17.74 respectively.At this altitude,the insect richness index,diversity index and community complexity index are also the highest,which are 2.92,3.07,0.99 and 5.42 respectively.The low altitude habitat showed the highest dominance index(0.33).To sum up,the altitude difference of Guancen Mountain is an important factor affecting insect community structure.
