Species abundance: A = abundant (>25%), C = common (16-25%), F = few (6-15%), R = rare (<1%), ? = questionable, - = absent. Size fraction = >63 µm
物种丰度(Species abundance)分级标准:A为丰度极高(abundant,占比>25%),C为常见(common,占比16%~25%),F为少量(few,占比6%~15%),R为稀有(rare,占比<1%),?为存疑(questionable),-为缺失(absent)。粒径分级(Size fraction):>63微米。
