摘要
本文根据厦门地区三个岛屿期间带调查所获的资料，研究了蟹类的种类组成与分布，并应用多样性指数分析了蟹类的结构特征。经鉴定的蟹类有14种55属91种，其中软相57种，岩相44种。软相的蟹类组成与岩相的明显不同。软相蟹类的多样性（H1）和均匀度（J）均大大高于岩相。蟹类的组成与分布受到底质类型、盐度和潮汐作用的综合影响。
The species composition and distribution of intertidal crabs are studied based in the data obtained from the seasonal surveys of three islands in Xiamen area from Febuary, 1990 to January, 1992,and the faunal structure of crabs are analyzed using diversity indices. Identified were 91 species belonging to 55 genera, 14 families, 57 species for soft intertidal zone and 44 for rocky zone. The species composition of crabs on soft beach is obviously different from that on rocky srashore. The values of species diversity (H' ) and evenness (J) for soft intertidal zone are much higher than those for rocky zone. The species comosition and distribution of crabs are comprehensively influenced by substrate type, salinity and tides.
