【摘要】：2015年5—9月,通过对河北雾灵山国家级自然保护区7个样点进行森林昆虫多样性普查,初步鉴定得到蛾类昆虫23科436种.针对该结果,使用Simpson多样性指数、Shannon-Wiener多样性指数、Pielou均匀度指数、Whittaker多样性指数和Margalef丰富度指数对其中分布较广的11科进行群落多样性分析,结果发现:雾灵山不同生境下蛾类昆虫多样性由大到小依次为针阔混交林带、农田带、寒温性针叶林带;不同海拔条件下物种多样性大小顺序为1 000~1 500m、500m以下、500~1 000m、1 500m以上;不同月份的物种多样性大小顺序为7月、8月、6月和5月.通过对五岔沟不同月份的物种多样性进行单独分析,发现该样点物种多样性情况与保护区整体不同,多样性大小顺序为7月、6月、8月.对不同的环境因素进行β多样性分析,发现蛾类昆虫的多样性受生境影响最大.综上,雾灵山蛾类昆虫的物种多样性和均匀度在各因素下差别不大,表明保护区整体环境良好,受人为干扰影响较小.
[Abstract]:From May to September in 2015, the species of moth insects belonging to 23 families and 436 species were preliminarily identified through a survey of forest insect diversity in 7 sample sites of Wulingshan National Nature Reserve in Hebei Province. Simpson diversity index Shannon-Wiener diversity index Pielou evenness index Whittaker diversity index and Margalef richness index were used to analyze the community diversity of 11 widely distributed families. The results showed that the diversity of moth insects in different habitats of Wuling Mountain was in order of coniferous and broad-leaved mixed forest, farmland and cold temperate coniferous forest, and the order of species diversity at different altitude was 1 000 ~ 1 500 m or less than 500 ~ 1 000 m ~ (-1 000) m ~ (1 500) m. The order of species diversity in different months was July, August, June and June. By analyzing the species diversity in different months of Wucha Gou, it was found that the species diversity of the sample was different from that of the whole protected area. The order of diversity was July, June and August. The 尾 -diversity analysis of different environmental factors showed that the diversity of moth insects was most affected by habitat. The species diversity and evenness of moths in Wulingshan are not different from each other, which indicates that the whole environment of the protected area is good and the influence of human interference is small.
