文章在传统的查全率和查准率检索评价指标，以及循证研究证据的分级体系和证据转化整合理论基础上提出的饱和度和冗余度科学性评价指标，为循证社会科学领域原始研究文献证据质量的科学评价提供了理论依据。文章依据饱和度评价指标对社会科学领域特定主题原始文献证据采用多种检索方式（参考文献迭代、代表性作者检索）进行系统性检索，构建了一个文献相关度分为高度相关、中度相关、低度相关的穷尽检索文献证据饱和数据集，进而为后续文献证据检索的冗余度等科学性评价提供了基础数据。

In order toimprove the quality of the original research evidence retrieval， present study proposed the concepts of saturation and redundancy based on the traditional retrieval assessment index such as recall and precision ratio for the purpose of construct a theoretical foundation for retrieval efficiency from the evidence-based research perspective. Taking the original documents of specific research topics in the field of Social Sciences in CNKI database as samples， this paper systematically searches， analyzes and grades the original document evidence by using a variety of retrieval methods， reference iteration and representative author retrieval for example， which is expected to provide a data basis for the quality evaluation of documentary retrieval in the further research procedure.
