本文研究有孔虫在台湾海峡的分布。海峡属于东亚大陆架的一部分,长约500公里,宽150公里,水深范围到150米。本文对沉积物中有孔虫组合的趋向作了描述,对生物相及其分布做了分析。有两类生物区系。一类是与沿大陆海岸的寒流、黑潮和深水水团构成的海洋水体有关;另一类与研究区的海底地形有关。通常有孔虫数量向陆架地形低的方向增加。搬运过的标体常见于表层沉积物中。总的说来,生物相是这样;粟虫科的种类分布于海峡的浅水 This article studies the distribution of foraminifera in the Taiwan Strait. The strait is part of the East Asian shelf, about 500 kilometers long and 150 kilometers wide with a water depth of 150 meters. This paper describes the tendency of foraminiferal assemblages in sediments, and analyzes the biofacies and their distribution. There are two types of biota. One is related to the ocean water body formed by the cold currents, the Kuroshio and the deep water masses along the coast of the mainland; the other is related to the seabed topography of the study area. Generally, the number of foraminifera increases in the direction of low shelf topography. Propagated objects commonly found in surface sediments. In general, the biological phase is the case; the branch of the family of Beppu lies in shallow waters of the Channel
