| 摘 要： | 间带不同性质的底质中 ,介形虫动物群的特征和生态分布各不相同。在岩石滩和沙滩中介形虫较丰富、多样 ,前者具有 Xestoleberishanaii,Cythere lutea lutea,Loxoconcha hattorii,Aurila cymba等 ,而后者有 Sinocytheridea impressa,Pistocythereis bradyformis,Bicornucytherebisanensis,Cushmanidea subjaponica等。泥质滩中介形虫通常很少 ,有 Loxoconcha binhaiensis和L.ocellata等。受高潮和中潮影响的河口区 ,通常介形虫丰度和多样性的分布较低 ,都是适应环境变化很强的属种 ,并具有海、陆相介形虫分布的混合区段。朝向海洋方向 ,非海相介形虫的百分含量呈逐渐降低变化 ,而海相介形虫正好相反。

| Abstract: | Ostracod faunal characteristics and ecological distribution are diverse from each other in different qualitative substrates of the tidal zone.Ostracods are relatively rich and diversified in the both rocky and sandy beaches,the former with Xestoleberis hanaii,Cythere lutea lutea,Loxoconcha hattorii,Aurila cymba, etc.and the latter with Sinocytheridea impressa,Pistocythereis bradyformis,Bicornucythere bisanensis,Cushmanidea subjaponica, etc.Usually,the Loxoconcha binhaiensis and L.ocellata et al.are very few on the muddy beach.The distributions of ostracod abundance and diversity are lower in general,genera and species are all very adaptive with environmental variance,and have a mixing zone of both marine and nonmarine ostracods in the estuarial region under the influence of both middle and high tides.The nonmarine ostracod percentage is gradually reducing toward the sea and marine ostracods are just the contrary. |
