摘要
DELTA系统是澳大利亚Dallwitz等人经过多年研究,开发出的一套用于分类学描述语言编码的国际标准。本文对该系统的主要功能,即自然语言描述、检索表、数据矩阵的自动生成、标本鉴定和信息检索以及分支分类运算和表征分类运算所需数据格式的转换等做了综述性介绍,以期促进该软件在我国广大植物分类学工作者中的推广与使用。
DELTA system developed by Dallwitz et al. is a flexible data-coding format for the concise representation and manipulation of taxonomic descriptions, and an associated set of programs for producing and typesetting natural-language descriptions and keys, for interactive identification and information retrieval, and for conversion of the data to formats required for phylogenetic and phenetic analysis. This paper is a general introduction to the functions included in DELTA system. We hope that it will promote the spreading and use of DELTA among plant taxonomists in China.
