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 %
研究結果如下：森林植物群落種的全年物種豐富度指數平均為64 . 688種，多樣性指數為2 . 982森林植物群落內各功能類群物種所佔比重依次為：草本層（平均為68 . 89 ） >喬木層（平均為15 . 266 ）灌木層（平均為15 . 845 ） 。森林昆蟲群落中，全年各功能類群所佔比重以植食性昆蟲類群為最大，平均佔0 . 729 ；捕食性昆蟲類群次之，平均佔0 . 136 ；寄生性天敵類群為最小，平均為0 . 135 。 -
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
結果表明：天山雲杉林分中草本層蓋度、苔鮮層蓋度、苔鮮層厚度、根系盤結層厚度、幼苗距大樹的距離5個環境變量之間為正相關；枯落物與草本層蓋度、苔蘚層蓋度、苔蘚層厚度、根系盤結層厚度、幼苗距大樹的距離為負相關；天山雲杉林微生境綜合因子可概括為「苔蘚」 、 「草本」 、 「空間距離」 、 「腐殖質」和「枯落物」 ；影響一年生幼苗更新最主要的微環境綜合因子為「枯落物」和幼苗距大樹的「空間距離」 。
