1定量古生物学软件PAST及其常用功能显示文摘近半个世纪以来,古生物学涉及越来越复杂的现象与过程,难以用传统的经验科学方法来解决。伴随着相关研究引入日益增多的定量分析,古生物学逐渐成为一门可定量分析的科学。作为最早的古生物学专用的免费统计软件包,PAST功能全面、易于使用,并在过去十几年中发展迅速,目前已在相关软件中占据重要地位。本文在简单介绍该软件基本操作方法的基础上,结合古生物学应用案例,解读最常用到的几类'常规统计分析'与'多元统计分析'的使用;同时,针对古生物学相关领域中的'多样性、丰度及居群结构','形态学'和'生物地层学'问题,给出具体分析实例。在相关案例的分析介绍中,详细梳理用PAST实现这些分析的具体步骤,因而具有较好的实用参考价值。受篇幅所限,文章对软件中其他不常用但相对重要的9个模块只进行简要介绍,以供读者在偶尔涉及该类分析时参考。PAST软件不仅功能强大,而且能够针对古生物学及地层学浮现出来的最新前沿问题不断进行调整、更新,值得在古生物学界推广使用。黄冰 David A T Harper φyvind Hammer 2013古生物学报2013,52,2:28
