资源简介:
species abundance: S = singel (<0.1%), R = rare (0.1%-1.0%), F = frequent (1%-10%), C = common (10%-30%), A = abundant (30%-50%), D = dominant (>50%), - = absent
物种丰度(species abundance)分级规则如下:S = 单一种(single,占比<0.1%),R = 稀有种(rare,占比0.1%~1.0%),F = 频见种(frequent,占比1%~10%),C = 常见种(common,占比10%~30%),A = 丰盛种(abundant,占比30%~50%),D = 优势种(dominant,占比>50%),- = 缺失(absent)
