资源简介:

Abundance: D = dominant >60%, A = abundant 30-60, C = common 15-30, F = few 3-15, R = rare <3, T = trace, X = present, - = none. Preservation: G = good, M = moderate, P = poor

丰度分级:D=优势种(Dominant),占比>60%;A=丰富种(Abundant),占比30%~60%;C=常见种(Common),占比15%~30%;F=少见种(Few),占比3%~15%;R=稀有种(Rare),占比<3%;T=痕迹种(Trace);X=存在种(Present);-=无(None)。保存状态分级:G=良好(Good),M=中等(Moderate),P=较差(Poor)
