摘　　要：通过对浙江长兴煤山剖面长兴阶上部和二叠系三叠系界线地层进行系统切片和研究,共鉴别出小有孔虫化石18属50种。这一丰富的有孔虫动物群,不仅进一步完善了长兴阶标准剖面的化石资料,而且也为研究二叠纪末的生物灭绝形式提供了新的依据。Fifty species in eighteen genera of non-fusulinid small foraminifers are identified from the middle and upper Changhsingian Stage and the Permian-Triassic boundary strata at the Meishan Section in Changxing, Zhejiang Province, where the standard Changxing Limestone and the GSSPs （Global Stratotype Section and Point） of both base and top of the Changhsingian Stage are located, based upon high-resolution samples at the section. This abundant foraminiferal fauna provides new data for a better understanding on the mass extinction pattern at the end of the Permian.
