本文描述了南千岛群岛国后岛潮间带群落大型底栖动物的垂直分布特征、物种组成和生物地理结构。在岩质和砾质潮间带，以藤壶Chthamalus dalli和腹足动物Littorina sitkana为主的群落是潮间带上层典型的大型底栖动物物种组成较差的群落。中潮间带为岩藻类组合。潮间带下层以海带藻类为主，大型底栖生物总生物量可达100 kg wet wt m−2。在由干净的沙子形成的波浪暴露的沙滩上，大型底栖生物的数量非常少，而且没有大型植物和其他附属形式。以大叶藻（Zostera japonica）和腹足类三角帆藻（Batillaria cumingii）为主的群落仅在伊兹梅尼湾国后岛南海岸的砂质潮间带发现。1963 ~ 1991年，伊兹梅尼湾大型底栖动物物种丰富度下降，生物量增加，这是由于该地区受到人类活动的影响。在国后岛潮间带发现大型底栖动物至少563种。太平洋低北纬和太平洋宽北纬物种占优势。与库纳希尔岛太平洋沿岸相比，伊兹梅尼湾潮间带和鄂霍次克海沿岸的温水物种更为丰富。这可能与大豆暖流的流动模式有关。库纳希尔岛潮间带大型底栖动物的种类组成和分布在低北纬潮间带具有典型的不规则日潮和半日潮。国后岛与邻近的色丹岛潮间带大型底栖生物群落的种类组成和分布格局相似。线虫、水螅、丝状棘球蚴、阴道棘球蚴、刺尾棘球蚴、相似棘球蚴、海蛞蝓、苔藓虫、三角虫和透明球蚴、海星、竹尾棘球蚴、日本棘球蚴、库氏棘球蚴、相似棘球蚴、海胆和其他无脊椎动物、各种海鞘和鱼类)。
Characteristics of vertical distribution, species composition and biogeographical structure of macrobenthos of the intertidal communities of Kunashir Island (South Kurile Islands) are described. In the rocky and bouldery intertidal zones, communities dominated by barnacle Chthamalus dalli and a gastropod species Littorina sitkana with the poor species composition of the macrobenthos are typical for the upper intertidal subzone. The middle intertidal subzone is occupied by fucoid assemblages. The dense beds of laminarian algae dominate in the lower intertidal subzone with the total macrobenthic biomass up to 100 kg wet wt m −2 . On wave-exposed sandy beaches formed by clean sand, populations of the macrobenthic organisms are very poor, and macrophytes and the other attached forms are absent. The communities dominated by eelgrass Zostera japonica and a gastropod species Batillaria cumingii are found only in the sandy intertidal zones of the southern coast of Kunashir Island, in Izmeny Bay. Reduction of species richness and increase of biomass of macrobenthos have been recorded from 1963 to 1991 in Izmeny Bay, and it is due to the fact that this area has been exposed to anthropogenic impact. At least, 563 species of macrobenthos are found in the intertidal zone of Kunashir Island. Pacific low-boreal and Pacific wide-boreal species are dominant. Warm-water species are more abundant in the intertidal zones of Izmeny Bay and on the Sea of Okhotsk coast as compared to those on the Pacific coast of Kunashir Island. It is probably associated with the flow patterns of the Soya Warm Current. Species composition and distribution of the intertidal macrobenthos of Kunashir Island are typical for the low-boreal intertidal zone with irregular diurnal and semi-diurnal tides. The intertidal zones of Kunashir Island and neighboring Shikotan Island have similar species composition and distribution patterns of the macrobenthic communities.
