资源简介:
Relative abundance: D = dominant, A = abundant, C = common, F = few, R = rare, T = trace, P = present (numerical values are abundance in percent)
相对丰度(Relative abundance)标注规则如下:D对应优势(dominant),A对应丰富(abundant),C对应常见(common),F对应少量(few),R对应稀有(rare),T对应痕量(trace),P对应存在(present);若以数值形式表征丰度,则其数值为以百分比表示的丰度值。
