实验结果表明，使用该算法进行预测得到的预测值接近真实值，准确性高于指数平均预测算法。 - 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 。
