herbaceous layer meaning in English
草本层
Examples
- The results showed : the relationships among cover of herbaceous layer , cover of liver moss layer , thickness of liver moss layer , thickness of root system twine layer and the distance between seedlings and adjacent tree were positive correlation ; the relation between litter and tile above five variables were negative correlation ; the variables of micro - habitat affecting seedling in the picea schrenkiana stand were generalized with moss , herbaceous , spatial distance , humus and litter ; litter and spatial distance between seedlings and adjacent tree were the most primary factors of micro habitat affecting regeneration of one year seedling
结果表明:天山云杉林分中草本层盖度、苔鲜层盖度、苔鲜层厚度、根系盘结层厚度、幼苗距大树的距离5个环境变量之间为正相关;枯落物与草本层盖度、苔藓层盖度、苔藓层厚度、根系盘结层厚度、幼苗距大树的距离为负相关;天山云杉林微生境综合因子可概括为“苔藓” 、 “草本” 、 “空间距离” 、 “腐殖质”和“枯落物” ;影响一年生幼苗更新最主要的微环境综合因子为“枯落物”和幼苗距大树的“空间距离” 。 - 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 。
