森林昆虫 meaning in English
forest insect
forest-insect
Examples
- There was significant correlation between forest plant community and forest insect community , namely constituting complexity of forest plant community had large influence on diversification of insect species composition
森林植物群落和森林昆虫群落间存在着显著的相关关系。即森林植物类群种的组成复杂程度极大影响昆虫种组成的多样化。 - The research object of this paper is the broad - leaved wood of red pine in north slope of changbai mountain . by analyzing the composition , construction , biodiversity and season diversity of forest community , we probed the rule of the forest community changing with the season and the ecological effect of forest insect community affected by forest plant community , appraised firstly regulating ability of forest ecosystem on forest pest and estimated finally effect of forest insect on ecosystem health
本文研究对象为长白山北坡红松阔叶林带，通过对森林群落的组成、结构、生物多样性及其季节变化，探索了森林群落生物多样性随季节变化规律，森林昆虫群落在森林植物群落的影响下的生态效应，对森林生态系统对森林害虫控制力作初步评价，最后对森林昆虫对生态系统健康影响作出评价。 - The research result is following : the annual species richness index of studied forest plant community averaged 64 . 688 , the species diversity index was 2 . 982 . the proportion of every functional group of forest plant community is : herbaceous layer ( average is 68 . 89 % ) > tall tree layer ( average is 15 . 266 % ) > shrub layer . ( average is 15 . 845 % ) the proportion of every functional group in forest insect communities is remarkably different , and the order of the proportion is herbivorous insect group ( average 0 . 729 ) > predatory natural enemy insect group ( average 0 . 136 ) > parasitical insect group ( average 0 . 135 ) . with seasonal change , the proportion of herbivorous and predatory insect group decreased obviously , while that of parasitical insect group increased on average by 147 %
研究结果如下：森林植物群落种的全年物种丰富度指数平均为64 . 688种，多样性指数为2 . 982森林植物群落内各功能类群物种所占比重依次为：草本层(平均为68 . 89 ) >乔木层(平均为15 . 266 )灌木层(平均为15 . 845 ) 。森林昆虫群落中，全年各功能类群所占比重以植食性昆虫类群为最大，平均占0 . 729 ；捕食性昆虫类群次之，平均占0 . 136 ；寄生性天敌类群为最小，平均为0 . 135 。
