较系统地总结了几十年来兴安岭地区奥陶纪生物地层研究的成果，以三叶虫化石为主对该区奥陶系进行了划分与对比，同时厘定了本区腕足类化石组合和笔石等重要化石层位，为兴安岭地区奥陶纪生物地层与我国华南、华北标准地区和其它地区以及与世界各区的对比提供了依据，同时为研究该区的地质问题提供了可靠的古生物资料。
The author systematically summarizes the research results of Ordovician bio-stratum in the Xinganling area over the past decades. The division and comparison of Ordovician in this area is mainly done by the trilobite fossils. At the same time, And other important fossil beds provide the basis for the Ordovician bio-stratum in the Xinganling area and the comparison of the standard areas in South China and North China and other areas in the world and with the rest of the world, and provide reliable paleontological data for the study of the geological problems in the area .
