资源简介:

Species abundances per traverse: R = rare (1-5 specimens), S = rare to frequent (6-15 specimens), F = frequent (16-35 specimens), M = frequent to common (36-75 specimens), C = common (76-150 specimens), L = common to abundant (151-300 specimens), A = abundant (301-600 specimens), V = very abundant (601-1000 specimens), W = very very abundant (1001-2000 specimens), X = extra abundant (over 2000 specimens). - = absent.

各采样路线的物种丰度分级标准如下:R:稀见(Rare),标本数量为1~5件;S:偶见至常见(Rare to Frequent),标本数量为6~15件;F:常见(Frequent),标本数量为16~35件;M:常见至多见(Frequent to Common),标本数量为36~75件;C:多见(Common),标本数量为76~150件;L:多见至丰富(Common to Abundant),标本数量为151~300件;A:丰富(Abundant),标本数量为301~600件;V:极丰富(Very Abundant),标本数量为601~1000件;W:超丰富(Very Very Abundant),标本数量为1001~2000件;X:特丰富(Extra Abundant),标本数量超过2000件;-:物种缺失。
