对1992年5月取自冲绳海槽北段（水深113-1156m，东经126°58.71’-129°9.06’，北纬28°41.75’-31°40.56’）92个表层沉积物中的底栖有孔虫数据进行R型因子分析。分析表明，黑潮流系有4个不同垂直水团的底栖有孔虫群落组合。其中Pseudorotaliaindopacifica,Bolovinarobusta,Cibicidesmargaritiferus,Textulariasaggitula,Cibicideslobatulus和Quinqueloculinaspp.代表黑潮流系的表层水;Hyalineabalthica，Caribeanelladepressa,Cibicidespraecinctus，Planulinawuellerstorfi和Melonisaffinis代表黑潮流系的次表层水;Globobuliminapacifica,Globocassidulinasubglobosa和Trifarinaspp.代表黑潮流系的中层水;Oridorsalistener,Martionottiellaokinawaensis,Pulleniaquinqueloba和Uvigerinadirupta代表黑潮流系的深层水。
A total of 92 surface sediments from the northern Okinawa Trough (depth 113-1156 m, longitude 126 ° 58.71’-129 ° 9.06 ’, latitude 28 ° 41.75’-31 ° 40.56’) in May 1992 ROL data for R-factor analysis. The analysis shows that there are 4 benthic and foraminifer assemblages in the Kuroshio Current with different vertical water masses. Among Pseudorotaliaindopacifica, Bolovinarobusta, Cibicidesmargaritiferus, Textulariasaggitula, Cibicideslobatulus and Quinqueloculinaspp representatives surface water black trend lines; Hyalineabalthica, Caribeanelladepressa, Cibicidespraecinctus, Planulinawuellerstorfi and Melonisaffinis on behalf of subsurface water black trend lines;. Globobuliminapacifica, Globocassidulinasubglobosa and Trifarinaspp on behalf of the black trend line Middle water; Oridorsalistener, Martionottiellaokinawaensis, Pulleniaquinqueloba and Uvigerinadirupta represent deep water of the Kuroshio Current.
