经３４个表层沉积物样品的有孔虫定量分析，表明苏北辐射沙洲沿岸潮滩的有孔虫为混合埋葬群，由原地生活分子和外海的异地分子混合而成。其特点是分异度偏高，丰度变化大，壳径偏小，壳体机械破坏较明显，富含壳径细小的浮游有孔虫。这些特点反映出埋葬群在形成过程中辐射沙洲区强大潮流的搬运作用，在搬运、沉积和埋葬过程中有孔虫壳体经受机械分选和破坏作用。埋葬群与生态环境因素和埋葬环境因素均有密切关系。
Quantitative analysis of foraminifera from 34 surface sediment samples showed that the foraminifera in the tidal flats along the radiation sand bank in northern Jiangsu is a mixed burial group consisting of in-situ molecules living in-situ and off-site molecules in the open sea. It is characterized by high degree of differentiation, abundance changes, shell diameter is small, more obvious mechanical damage to the shell, rich in shell diameter flotation foraminifera. These characteristics reflect the handling of the powerful tidal currents in the sand burial area during the formation of burial mounds. The foraminifera shells undergo mechanical sorting and sabotage during handling, deposition and burial. The burial group is closely related to the ecological environment factors and burial environmental factors.
