摘　　要：就现场提取的生物检材而言,我们除了需要准确获得DNA STR分型进行个体识别和亲子鉴定,还希望能够通过技术手段获知其遗留时间、空间定位等更多信息。本文以血迹为主要研究对象,就国内外采用光学、细胞生物学、分子生物学等方法推断生物斑迹遗留时间进行总结,并对法医微生物学这一法庭科学新领域在时空线索推断中的应用做以介绍,为现场生物斑迹遗留时间推断研究提供参考。In addition to obtaining DNA-STR typing of an evidentiary stain for individual identification and paternity tests, knowing the time since deposition（TSD） is also highly desired in forensics. To provide a reference for the research of predicting the TSD, this article reviews the reported optical, cell biological and molecular biological methods of determining the age of bloodstains domestic and overseas, and also introduces the application of microbial forensics, a new field of forensic science, to provide space-time clues of evidentiary stains.
