摘要
2008年7月～10月,通过对秀山岛潮间带蟹类进行调查,共采到蟹类15种,分隶属于4科11属,其中9种属于方蟹科,分布很广;有4种属于沙蟹科,弧边招潮蟹(Uca arcuata)在数量上占绝对的优势,为整个秀山岛潮间带的优势种;有1种属于梭子蟹科,为锯缘青蟹(Scylla serrata);玉蟹科为一种,即豆形拳蟹(Philyra pisum),只分布在滩涂,且数量很少。随着潮滩湿地开发,蟹类的生境正在发生变化,尤其是造船业在秀山岛大规模的建立,将会对弧边招潮蟹等穴居性蟹类产生更大的影响。
After a survey to intertidal crabs in Xiushan Island from July to October of 2008,totally 15 species of crabs were collected those belong to 4 families and 11 genuses.Among of them,9 species belong to Grapsidae which distributed widely;4 species belong to Ocypodidae,especially Uca arcuata which is in absolute advantages in quantities becomes dominant species in the entire intertidal zone of the Xiushan island;1 species which belongs to Portunidae is Scylla serrata.And Philyra pisum,belongs to Leucosiidae,which has few number and only exists in the beach.With the development of tidal wetlands,the habitats of the crabs is changing,particularly the large-scale foundation of shipbuilding industry in Xiushan Island,which has a greater impact on cave-crabs,such as Uca arcuata.
