摘要
本文根据1984年10—11月和1985年4—5月对闽江口以北沿岸潮间带16条断面的生态调查,总结了该区软体动物的分布、种类组成,探讨了其与环境因子的关系。结果表明,该区软体动物187种,属5纲13目61科。其中腹足纲100种、瓣鳃纲74种。岩岸生物量最高(421.71g/m^2)、密度761.1个/m^2;垂直分布以岩礁和砂质岸的低潮带最高。在种类组成上以暖水性种类(占55％)为主,广温广布种占42.8％。全区种类多,数量大,经济种和主要种占41.2％,应予以开发。
Reported in the present paper are the preliminary results of the ecological investigation on Molluscs during the period of October and November in 1984 and April and May in 1985 in the intertidal zone north to Mingjiang river,Fujian Province.A total of 187 species of Molluscs were found in the investigation,of which,8 species belong to Polyplacophora.74 species to Lamellibranchia.100 species to Gastropoda,1 species to Scaphopoda and 4 species to Cephalopoda.The dominant and commercial species make up 43%of the total,of which.54%species were also found in the coast of Zhejiang Province and 66%species in the coast of the South China Sea.The total biomass and density of the rocky zone(421.71 g/m^2 and 761.1 ind./m^2),the muddy sandy zone(18 97 g/m^2 and 455 1 ind/m^2),the muddy zone(10.19 g/m^2 and 125 0 ind/m^2),the mangrove zone(7.84g/m^2 and25.7 ind./m^2)and the sandy zone(3,24 g/m^2 and 39 ind/m^2)are reported.The composition,number and species distribution are related to tidal actions,salinity of substrata,organic material content,seasonal variation and wave intensity.
