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)分级如下:S = 极稀级(<0.1%),R = 稀有级(0.1%~1.0%),F = 频见级(1%~10%),C = 常见级(10%~30%),A = 丰富级(30%~50%),D = 优势级(>50%),- = 缺失
